Why Are Quantitative Funds Losing Coin These Days?

The New York Times today has an article close several well-known quantitative hedge funds incurring pregnant losses inwards recent months. I was quoted inwards proverb that traders running like quantitative models could contribute to marketplace position volatility. This is for sure truthful if the strategies are trend-following. What puzzles me, however, is that most statistical arbitrage strategies are mean-reverting: they purchase during investors' panic, together with sell during investors' euphoria, together with should move richly rewarded inwards this volatile marketplace position yesteryear providing sorely needed liquidity. And indeed, from my ain sense besides equally hearing from other traders, mean-reverting strategies are performing rattling good recently. So where did those losses come upward from? My approximate is that, equally I bring observed before, many traditional stat arb strategies are getting tiresome together with generating diminishing returns, together with thus many of the quantitative researchers are driven (by their ain professional person pride or their bosses) to come upward up alongside to a greater extent than exotic together with higher-return strategies that ultimately may non stand upward the exam of time. For us quants, remembering Occam's razor together with that our project is to generate returns equally opposed to producing vivid mathematical models is oft a difficult lesson to learn.

An Update On Why Quantitative Funds Are Losing Coin Recently

A even out only came through Dow Jones newswire ("How Black Boxes Became Pandora's Boxes" past times Spencer Jakab) suggesting that recent losses are due to element models gone bad. Given my expressed distaste for such models, that should convey been my begin estimate instead of blaming the "exotic" models!

A Reader's Comment On Quant Funds' Losses

A reader of mine (who want to rest anonymous) pointed out that virtually of the losses appear to come upwards from low-frequency trading models, piece high frequency models popular off along to perform superbly. This too confirms my ain experience. My enthusiasm for high frequency trading was expressed previously here as well as here.

Cnbc Interview

Folks, I volition endure appearing on CNBC tomorrow (Tue, August 14) for a alive interview virtually quantitative trading amongst Maria Bartiromo. The segment volition endure aired to a greater extent than or less 3:20 pm ET.

Cnbc Interview Video

Here is the link to my interview on why quantitative models are losing coin of late:

The Robin Hood Regime

It has move apparent to me inward the final calendar month that in that location has been a massive transfer of wealth from the gigantic hedge funds running ingredient models to many day-traders amongst accounts less than $10M. I telephone phone this the Robin Hood authorities (regime being a mutual technical term referring to a detail trading environment, every bit inward "this is a mean-reverting regime"). Many, many day-traders that I heard from get got had i of their best months inward a long while. Is this exactly luck, or is in that location a deeper explanation?

I believe that in that location is a philosophical divergence betwixt ingredient models as well as many of the mean-reverting strategies that day-traders similar to employ, a divergence that plant to the day-traders' favor. I scream upwards a wise musing from i of my one-time bosses: he believes that a trading strategy volition survive profitable inward the long run exclusively if it performs a service for other marketplace participants. The service that mean-reverting strategies performs is the provision of liquidity, inward particular, short-term liquidity. What service does ingredient models provide? They appear to survive exactly arrogant bets on the correctness of the managers' convictions. For e.g. I believe that stocks amongst skilful earnings volition rising inward value. Or, I believe that stocks amongst increasing toll momentum volition hold inward that momentum. True, close of the fourth dimension the convictions of the best managers are correct, as well as many of these convictions are truly mean-reverting too (for e.g. the "value" factors). But on average, a ingredient model may convey away every bit much liquidity from the marketplace every bit it provides. And sooner or later, exactly about of these convictions are wrong. Maybe non incorrect for really long, but long plenty to displace investors' panic. This may survive business office of what nosotros are seeing recently.

Now am I advocating that every gigantic fund but exactly switch from ingredient models to pure mean-reverting strategies? No: that would survive impractical when the portfolios involved are inward the tens of billions. If everybody run mean-reverting strategies, in that location volition hardly survive whatever mean-reversion left to net from. (Look what happened to pair-trading inward the final few years.) When y'all are an investor inward a multi-billion fund, as well as y'all hold off the fund to deliver higher returns than the risk-free rate, y'all exactly get got to convey that high short-term returns volatilities volition survive business office of the bargain, exactly similar whatever long-term investments.

The Failed Factors Convey Reverted

As I said inwards my CNBC interview, investors merely got to hold out patient amongst the component subdivision models. Sure enough, nosotros are seeing reports that the large drawdown suffered past times these models has already reverted every bit of Friday.

Further Fighting On Element Models

A reader from a hedge fund (who wishes to rest anonymous) sends me about thoughtful comments almost element models. He has graciously allowed me to reprint them here:

"With regards to your weblog entry, 'The Robin Hood regime': this weekend I was truly too thinking almost the philosophy behind element models which y'all allude to inward the post. I am wondering if y'all own got whatever other thoughts equally to what service element models provide? Relegating them to 'just arrogant bets on the correctness of the managers' convictions' isn’t completely intellectually satisfying to me.

I facial expression at factors equally such: the returns I acquire for exposure to diverse factors tin hand notice come upward either because the marketplace is inefficient as well as systematically misprices those factors (alpha), and/or because I am providing about service via the exposure (and collecting about variety of guide chances premium associated amongst that service). My query #1 to y'all is, are y'all convinced that all of the returns to element models are indeed exactly from guide chances premiums as well as non alpha? If alpha exists, it’s less clear that a service needs to live on provided to the market, at to the lowest degree to me.

However, let’s assume (as I believe your boss did) that inward the long run, the marketplace is efficient. Then, y'all volition live on compensated for element exposure entirely past times bearing about guide chances or providing about service. In my mind, about detail conviction of a managing director doesn’t necessarily qualify for a guide chances element inward as well as of itself - I recall nosotros concur on that point. But are at that topographic point possible fundamental, valuation-based explanations behind these factors? Perhaps depression VALUE companies are mostly those companies amongst bad recent surgical procedure but which are expected to turnaround / mean-revert (as y'all somewhat propose inward your post) as well as the guide chances y'all conduct when buying a depression P/E fellowship is “turnaround risk”. Or mayhap high MOMENTUM companies are companies riding an manufacture tendency as well as y'all are bearing “trend continuation risk”. So, my query #2 to y'all is, are y'all convinced that at that topographic point are no such explanations?

If element models produce indeed work, it seems to me that at that topographic point must either live on existent risks behind the factors, or alpha, or both."

And hither is my response:

"I believe the service that about value factors render is the efficient resources allotment of uppercase to those companies that deserve them, exactly similar whatever value investors do. In this case, the factors promise to position these companies faster than humans can, as well as hence select uppercase to them sooner. I own got no declaration amongst these factors equally they too render liquidity, albeit on a longer time-scale. However, amongst regard to diverse momentum factors, they are inward fact exactly betting on for certain behavioral characteristics of investors, or on the ho-hum dissemination of news, etc. You tin hand notice debate that they render a service past times improving the efficiency amongst which data almost companies disseminate. But the work is that i time everybody are using these momentum factors, the marketplace becomes efficient as well as whatever farther bets generate losses.

So I am quite willing to select that many of these (momentum) factors stand upward for alpha, but these factors are generating to a greater extent than losses equally to a greater extent than investors employ them. I am too willing to select that many of the (value) factors stand upward for guide chances premia. As to a greater extent than investors employ these, the net goes to zero, but fortunately non negative equally the guide chances too disappears."

The Perils Of Momentum Strategies

Not as well as then long agone I was an agnostic with honour to choosing betwixt mean-reverting as well as momentum models: I felt that depending on the item model or environment, each tin live profitable. Lately, however, I am increasingly skeptical nigh the long-term profitability of momentum models. The principal ground is the increasing contest with traders, algorithmic or otherwise.

As I mentioned inward my previous post, when to a greater extent than as well as to a greater extent than traders create upwards one's psyche to adopt mean-reverting strategies, all they exercise is to eliminate the trading opportunity. The marketplace becomes efficient, as well as nobody makes whatever money, but nobody loses either. In contrast, when to a greater extent than as well as to a greater extent than traders create upwards one's psyche to adopt momentum strategies, the momentum volition live established sooner as well as sooner. For e.g. inward the instance of event-driven strategies which are mostly momentum-based, the novel equilibrium cost volition conduct keep been established almost instantaneously afterwards the number is publicly disclosed. Under this circumstance, whatever momentum trades that are entered merely a footling fleck belatedly volition non alone endure zilch profit, but volition probable endure losses equally mean-reversion almost inevitably takes over. But how before long exercise nosotros take away to motility into inward gild to avoid this fate? (It can't live likewise before long either because frequently a tendency take away to live established outset inward gild to trigger an entry signal.) It is unfortunately a moving target equally contest increases: 1 24-hour interval before mightiness move now, but may non live sufficient a few months from now. (The move out merchandise also suffers the same problem, equally nosotros don't know how long the momentum volition last.) It is a unsafe game to play.

Indeed, fourth dimension is frequently a friend of the mean-reversion trader: the longer s/he waits, mayhap the to a greater extent than profitable the trading opportunity. And if s/he enters likewise early on as well as suffers a loss, s/he tin e'er double the position. As I explained inward a previous article, stop-loss should to a greater extent than frequently than non not live applied to mean-reverting trades on a brusque time-scale. So fifty-fifty if the trader does non double-up the position, an eventual re-couping of the loss is to a greater extent than than likely. On the other hand, fourth dimension is an enemy of the momentum trader: if s/he loses the first-mover payoff as well as suffers heavy loss, I argued inward that article that a stop-loss is advised, as well as therefore the loss is forever locked-in.

Given this asymmetry, it is no wonder that algorithmic traders conduct keep been alarm me long agone that it is difficult to discovery a profitable momentum trade. And I was giddy plenty non to pay psyche to them until now.

Cio Magazine Project Design Together With It Strategy Blog

Ms. Elana Varon who writes the CIO Magazine's article of mine is an elaboration of my sentiment on this.

Whatever Happened To The Xle-Uso Spread?

Recently Mr. Teetor, a subscriber of mine, has posted an enthusiastic comment on trading the XLE-USO spread that I suggested. While Mr. Teetor has a lot of success trading this spread, I must tell that I bring lost religious belief inward the cointegrating feature of this spread because of ii reasons:

1) The spread appeared to bring experienced a regime-shift since the historic backtest menstruation earlier August 2006: the out-of-sample functioning of the spread since so did non back upwards cointegration; and

2) The key declaration inward back upwards of cointegration betwixt XLE as well as USO cruel apart upon closer investigation.

The ii reasons are, I believe, intertwined. Unlike GLD (part of a much to a greater extent than cointegrating spread that I discussed as well as tracked inward my premium content area), USO does non genuinely concur commodity assets inward its portfolio. It holds nearby futures contracts inward oil. When the USO fund started trading inward Apr 2006, its cost per portion was really around the spot petroleum price. Now, however, USO is trading at virtually $53, acre spot petroleum cost is at virtually $70.6. How tin give the sack a fund that is supposed to reverberate petroleum cost diverge so much from it subsequently a yr as well as five months? The ground is that the petroleum futures marketplace has been inward contango since 2005 or so, i.e. far calendar month futures costs to a greater extent than than the nearby contracts, which results inward negative roll-yield for long seat inward petroleum futures. In the age from which the XLE-USO cointegration relation was established, petroleum futures marketplace exhibited backwardation: far calendar month futures cost less than nearby futures. This authorities shift partially explains the breakdown of the cointegration relation inward the acquaint out-of-sample period.

The lesson I bring learned from all these is to avoid analyzing cointegration relation when either side of a spread involves futures contracts at dissimilar points of the frontwards curve, at to the lowest degree on a time-scale when the shape of that crease mightiness change. (I argued earlier that XLE, the other side of the spread, tin give the sack hold out modeled every bit an average over the entire frontwards curve.) Meanwhile, the fund managing director of USO would genuinely bring done investors a much meliorate favor past times getting their hands dirty, leasing some petroleum storage tanks as well as buying some existent petroleum assets rather than keeping their hands build clean as well as dealing inward futures contracts alone. After all, retail investors similar myself tin give the sack simply every bit easily purchase petroleum futures ourselves, but nosotros can't really good become out as well as rent an petroleum tank.

More Give-And-Take On Returns, Opportunity Together With Leverage

Previously I discussed an of import debate on whether it is amend to growth a portfolio's provide past times taking on to a greater extent than risks (e.g. belongings high-beta stocks), or past times increasing leverage precisely belongings low-risk assets. H5N1 reader Mr. F. Sudirga has kindly mail me another interrogation papers supporting the decision that increasing leverage is the preferred way.

In a newspaper titled "Risk Parity Portfolios", MD Edward Qian at PanAgora Asset Management argued that a typical 60-40 property resources allotment betwixt stocks as well as bonds is non optimal because it is overweighted amongst risky assets (stocks inwards this case). Instead, to laissez passer on a higher Sharpe ratio land maintaining the same endangerment score equally the 60-40 portfolio, MD Qian recommended a 23-77 resources allotment land leveraging the entire portfolio past times 1.8. The stock-bond dichotomy is for example alone -- the results tin live on improved farther past times including other property classes such equally commodities.

The alone reservation I accept amongst all this enthusiasm amongst increasing leverage is i that many risk-managers are aware of: virtually of the interrogation uses concepts such equally measure deviations to mensurate risk. But equally the LTCM debacle also equally the recent subprime mortgage meltdown has reminded us, risky events accept fat-tailed distributions. Therefore, i should live on really wary of using measure difference equally the sole determinant of leverage.

Hedge Fund Replication

I wrote about how hedge fund returns tin forcefulness out survive replicated alongside uncomplicated ingredient models. I but larn that IndexIQ, a fellowship inward Rye Brook, NY, has just launched such products available to retail investors every bit managed accounts.

So How Much Did Quantitative Strategies Genuinely Lose Final Quarter?

The numbers convey started to come upwards in: Morgan Stanley lost $480MM concluding quarter due to quantitative trading -- close 10% of operating profits.

How A Mean-Reversion Strategy Performed Inward August

Prof. Andrew Lo in addition to Mr. Amir Khandani at MIT of late wrote a newspaper on "What Happened To The Quants In August 2007?" (Hat tip to my reader Mr. J. Rigg for the article). Most of their conclusions confirm what many observers already suspected: that the loss is probable due to the simultaneous forced liquidation of portfolios belongings similar positions past times diverse quantitative funds. What is noteworthy, however, is that they constructed a mean-reversion strategy in addition to observed what happened to it during August. This strategy is really simple: purchase the stocks amongst the worst previous 1-day returns, in addition to brusk the ones amongst the best previous 1-day returns. Despite its speak simplicity, this strategy has had corking functioning since 1995, ignoring transaction costs. The Sharpe ratio was an astounding 53.87 inwards 1995, gradually decreasing to 4.47 inwards 2006. However, the strategy also had a disastrous few days on August 7-9, suffering a cumulative (arithmetic) furnish of -6.85% inwards those 3 days. Then on August 10, it rebounded, similar the remainder of the quant funds, amongst a furnish of 5.92%, most reversing all of its previous losses. For me, this experiment reveals 3 interesting points: 1) a uncomplicated cost element seems to capture most of the functioning of the complex element models hold out past times the gigantic hedge funds; 2) fifty-fifty technical mean-reverting factors endure losses, non only momentum (growth) factors based on fundamentals; in addition to 3) if i wants to avoid disasters in addition to taste spectacular returns, fifty-fifty a one-day belongings menstruum is besides long. I haven't done the experiment myself yet, but I bet that if nosotros were to liquidate the portfolio at marketplace unopen each day, non alone would nosotros avoid the loss of -6.85% inwards those 3 days, but would in all likelihood cease upwards amongst a positive furnish of a similar magnitude!

Emerging Markets Stocks Vs. Natural Resources Stocks

Emerging marketplace stocks convey been reaching novel highs nigh everyday (see this proposed before, its value is at an all-time-low these days -- it was at -6.77 touchstone deviations. Given their historical cointegration, I wouldn't survive surprised if it volition revert to a to a greater extent than sane value inward the close future.

Economist Article On Quant Funds

The media seems to bring an endless fascination amongst quant funds. Here is the latest article from the Economist magazine, summarizing the postmortem published yesteryear several researchers. (Hat tip, in 1 lawsuit again, to reader Mr. J. Rigg.)

The telephone substitution points are equally follows:

1) Quant funds are immediately becoming the mind marketplace makers inwards many securities, which commonly would render liquidity as well as decrease volatility.

2) Unlike ordinary marketplace makers, however, quant funds are highly leveraged.

3) Because of the high leverage, inwards the confront of large losses these market-making quant funds are forced to liquidate their assets instead of buying them, hence behaving inwards a mode contrary to ordinary marketplace makers simply when the involve for liquidity is direst.

4) Thus quant funds are truly contributing to instability of the marketplace despite their apparent market-making function.

Fortunately, when all else has gone wrong, at that spot is alway Mr. Bernanke to count on ...

Seasonal Trades Inwards Stocks

Readers of this weblog convey seen my discussions of diverse seasonal trades inward commodities futures (e.g. come across this article). Recently, Mark Hulbert of the NYTimes drew our attending to a seasonal merchandise inward stocks. The strategy is really simple: each month, purchase a lay out of stocks that performed the best inward the same calendar month a twelvemonth earlier, in addition to brusque the same lay out of stocks that performed poorest inward that calendar month a twelvemonth earlier. The average annual provide is to a greater extent than than 13% before transaction costs, in addition to since it is marketplace neutral, this already considerable provide tin post away survive leveraged to ii or three times higher. Also, since it turns over the stocks exclusively in i lawsuit a month, transaction costs should non survive a major problem. The strategy was developed past times Profs. Steven Heston in addition to Ronnie Sadka, in addition to details tin post away survive establish online here. Besides its simplicity, the strategy is non every bit affected past times survivorship bias inward the information laid every bit a mean-reverting strategy, since survivorship bias would tend to lower its backtest surgical physical care for past times excluding really poorly performing stocks that nosotros would short. All inward all, it seems to survive a marketplace neutral strategy made for retail trading!

A Body Of Body Of Water Of Pain

This Economist Magazine article confirms my personal sense that value investing is inwards a bounding main of hurting at the moment. The reasons are quite dissimilar from the final fourth dimension (during the dotcom era) when value investing was inwards the doldrums. This fourth dimension around, people are non amount of euphoria most the prospects of increase stocks -- they are merely getting increasingly gloomy of value stocks which look to last getting cheaper past times the minute.

Are Quant Strategies Inward Problem All The Same Again?

There were reports that quant strategies convey been suffering 1 time again inward January, given the marketplace set turmoil generated partly past times the Societe Generale scandal. Mr. Matthew Rothman of Lehman Brothers pinned the blame on momentum strategies (Hat tip: previous post, Dec has been a disastrous calendar month for value (or mean-reverting) strategies, based on both populace commentaries in addition to personal experience. Yet, every bit always, mean-reverting strategies bounced dorsum inward Jan in addition to all the hurting is gone. In fact, the Societe Generale scandal in addition to the subsequent 1/22 Fed bailout has been a huge bonanza to mean-reversion traders, but similar the August disaster had been. (Remember: mean-reversion traders net turn a profit from providing liquidity during marketplace set panic.) Meanwhile, though Dec has been a skilful calendar month for momentum strategies, Jan has acquire increasingly inhospitable to them. But 1 should non live on surprised at all. As I convey explained before, momentum strategies by in addition to large tend to live on to a greater extent than unstable in addition to convey lower Sharpe ratios than reversal strategies. Any wise quantitative portfolio managers would ever allocate a lower proportion of working capital missive of the alphabet to momentum strategies than to reversal strategies. Hence it is no excuse at all to say that a quant portfolio has been wound past times losses inward momentum trading -- they are to live on expected quite frequently!

Looking For Momentum? Banking Concern Lucifer Exterior The Us

Momentum vs. mean-reversion has been a perennial subject inward investing, non to the lowest degree quantitative investing. My disceptation has ever been that momentum strategies are by together with large less reliable than mean-reversal strategies. (See here or here.) My reader Mr. J. Rigg told me virtually a recent article inward the Financial Times suggesting that momentum strategies are hold out together with well, according to the research yesteryear Prof. Elroy Dimson et al at the London Business School. The strategy is really simple: purchase the stocks amongst the highest returns in, say, the terminal 12 months, brusk the ones amongst the lowest returns, together with concur for, say, 1 month. If y'all run this strategy for the summit 100 Great Britain stocks from 1900 to 2007, the average annualized homecoming earlier costs is virtually 10%.

There are, however, a publish of caveats worth noting inward this study:

First, it is really transaction-costly to implement momentum strategies for small-scale or fifty-fifty mid-cap stocks. If y'all element inward costs, 10% tin easily move 5% -- non an impressive publish fifty-fifty for a dollar-neutral strategy. (Though i should complaint that the infrequent rebalancing renders transaction costs consideration less important.)

Second, the drawdown durations are quite lengthy -- sometimes exceeding two years. This is non acceptable functioning for many hedge funds. Such lengthy drawdowns induce got been a mutual characteristic of many momentum strategies that I induce got personally studied together with traded.

Third, together with most interestingly, inward the menstruum 2001-2007, this momentum strategy has stopped working altogether for the U.S.A. market, acre continuing to deliver positive returns inward other markets!

What may hold out the argue for this dichotomy betwixt U.S.A. together with international markets? Momentum strategies by together with large derive their ability from the dull diffusion together with analysis of information: if all investors are simultaneously aware of all the relevant fiscal data virtually a companionship together with tin analyze the significance of the data instantaneously, they volition induce got come upwards to a consensus fair marketplace position value instantaneously together with no momentum inward the cost volition result. Hence mayhap the disappearance of momentum inward the U.S.A. equity marketplace position way what most people know already: that it is the most efficient equity marketplace position of all.

Had It Been Actually That Bad?

According to Eurekahedge Hedge Fund Index, hedge funds had the worst surgery inwards 8 years during this by January. And long-short equity funds had the poorest surgery amid them all.

5 Steps To Managing Adventure Equally A Microfinancier

It powerfulness surprise to a greater extent than or less of yous that lending coin to middle-class American abode owners to purchase houses may live on much riskier than lending coin to Bangladeshi farmers to purchase their get-go cellphones. (The beauty of diversification at operate here?)

5 Steps to Managing Risk equally a Microfinancier

By Heather Johnson

Microfinancing is a growing tendency amidst investors, equally it offers low-risk coin opportunities as well as a agency to convey social modify to poverty-stricken communities. "Low-risk" doesn't equal "no risk," of course, thence many potential microlenders are corking to larn the ins as well as outs of credit run a jeopardy administration inwards this arena. After all, most microborrowers select pitiable credit or no credit at all. Influenza A virus subtype H5N1 villager who needs $200 for starting a third-world chicken farm isn't going to fare good inwards that department, equally yous tin ship away imagine.

The adept intelligence is, fifty-fifty inwards the effect of a loan delinquency, yous won't live on losing a substantial total of money. Most microloans hit from a few hundred to a few chiliad dollars. Any losses are unfortunate, though, thence yous volition desire to create out your microlending risks as well as expire along loan delinquencies to a minimum.

Here are 5 steps to managing your run a jeopardy equally a microfinancier:

1. Research Your Borrower – If you're lending through a site, such equally Prosper, as well as then yous volition select access to your borrower's profile as well as credit reports. However, don’t live on afraid to inquire to a greater extent than questions if yous select whatever doubts most this person's powerfulness to repay the loan. If yous are lending the coin through other channels, definitely start amongst the credit reports as well as interview the borrower.
2. Lend With a Group – Though this won't brand your borrower whatever to a greater extent than probable to repay a loan, lending amongst a grouping volition assist to spread out the toll as well as part responsibility. In other words, yous volition live on risking less coin as well as volition select other people amongst the same interests to consult with.
3. Use Analytical Tools – Third-party applications tin ship away assist yous create upwards one's heed what is working best amongst your microlending. Both seasoned microlenders as well as newcomers are highly encouraged to utilisation such tools. Microfinance sites that come upwards amongst fantabulous built-in tools include Trickle Up, Opportunity International as well as Heifer International.
4. Provide Incentives – Consider an incentive plan for those who pay on time. Influenza A virus subtype H5N1 small, cheap gift volition live on real appreciated past times those living inwards third-world countries. Lenders select used food, such equally rice or corn meal, equally a bonus.
5. Be Proactive inwards Collecting – This doesn't hateful yous should harass your borrowers. However, yous should enquiry your delinquent accounts equally presently equally payments are late, rather than letting them expire into default. There could live on a elementary breakdown inwards communication or an emergency on the borrower's end.

One of the biggest draws of microfinancing is the relatively depression run a jeopardy involved. However, that doesn't hateful that yous volition select a 100% success rate. The best agency to acquire your feet moisture is to start amongst a pocket-size loan. Something equally depression equally $100 volition permit yous larn the procedure as well as allow yous to acquire to a greater extent than comfortable amongst the system. Microfinancing isn't for everyone, but yous may but honour your niche amongst this sort of investment.

A Combination Momentum Together With Hateful Reversal Model Based On Lucre Annoucements

Mark Hulbert of the New York Times only discussed ii momentum strategies investigated past times professors David Aboody, Brett Trueman in addition to Reuven Lehavy.

Strategy A: option stocks inward the elevation percentile of 12-month returns. Buy them (individually) five days earlier their earnings announcements in addition to sell them only earlier the announcement.

Strategy B: option stocks inward the elevation percentile of 12-month returns. Buy them (individually) five days right away later their earnings announcements in addition to agree them for five days.

Strategy Influenza A virus subtype H5N1 is really profitable: the annualized excess furnish is 47% earlier costs. (To survive taken alongside a grain of tabular array salt due to the large transaction costs associated alongside trading momentum strategies, peculiarly if small-cap stocks are involved.) Strategy B is really unprofitable: the annualized excess furnish is -43% earlier costs.

So what are the ways nosotros tin reach the axe brand best locomote of this research?

Naturally, instead of buying the elevation percentile later the earnings announcements, nosotros should hit got shorted the stocks, so making Strategy B a reversal strategy instead.

Furthermore, what virtually the bottom percentile of stocks? Should nosotros hit got shorted them prior to the announcements, in addition to bought them later the announcements? If so, nosotros would hit got a really dainty dollar-strategy for you lot statistical arbitrageurs out there!

5%: An Of Import Position Out For Existent Estate Investors

Equity investors similar to cheque out a company's price/earnings ratio earlier they invest inwards its stock. Likewise, existent estate investors should produce the same earlier buying a house. The equivalent of price/earnings ratio for existent estate is the price/rent ratio, or inversely, the rent/price yield.

What is a reasonable rent/price yield for USA residential existent estate? According to Morris Davis of the University of Wisconsin-Madison, in addition to Andreas Lehnert in addition to Robert Martin of the Fed, the long-term average is 5% (i.e. the annual rent of a household should last virtually 5% of its marketplace lay value). As the Economist magazine has reported, at the peak of the USA housing boom, this figure dropped to equally depression equally 3.5%.

Currently, this ratio is at virtually 4.3%, which implies that average USA housing toll has to drib approximately other 14% inwards society to furnish to its historical fair value.

Can quantitative traders net turn a profit from this prediction? Well, nosotros tin e'er curt the S&P/Case-Shiller Home Price Indices futures at the Chicago Mercantile Exchange.

Are High Crude Prices Due To Hedge Fund Speculation?

The economist Paul Krugman advances an interesting declaration today inwards the New York Times against the thought that high fossil oil prices are due to hedge fund speculation.

He believes that speculative buying tin Pb to persistent high prices (which has been the illustration for the end few years) solely if at that topographic point is physical hoarding. Yet fossil oil inventory degree has been normal for this period.

Indeed, I convey been trying to honor a mean-reverting strategy to merchandise fossil oil in addition to oil-related assets for to a greater extent than or less fourth dimension now. So far, none convey outperformed (even on a risk-adjusted basis) merely buy-and-hold unloosen energy stocks for the long term!

Machine Learning + Authorities Switching = Profitability?

My article on a trading strategy based on authorities switching as well as machine learning techniques is immediately available on Automated Trader magazine (subscription required). The software I used to query this model is Alphacet Discovery, an industrial-strength backtesting, optimization, as well as execution platform.

Parameterless Trading Models

A portfolio managing director that I used to piece of job for similar to pronounce that his trading models convey "no complimentary parameters". As is customary inwards our secretive industry, he would non elaborate farther on his technique.

Lately, I get to empathise what a trading model amongst no complimentary parameter means. It doesn't hateful that it does non incorporate whatever lookback menses for calculating trends, or thresholds for entry or exit. I recall that would hold upward impossible. It merely agency that all such parameters are dynamically optimized inwards a moving lookback window. This way, if you lot ask: "Does the model convey a fixed net turn a profit cap?", the trader tin honestly reply: "No, net turn a profit cap is non an input parameter. It is determined yesteryear the model itself."

The wages of a parameterless trading model is that it minimizes the danger of overfitting the model to multiple input parameters. (The so-called "data-snooping bias".) So the backtest functioning should hold upward much closer to the actual frontwards performance.

Now, it is quite computationally challenging to optimize all these parameters just-in-time for your side yesteryear side order, but it is oft fifty-fifty to a greater extent than hard to produce that inwards a backtest, given that a multidimensional optimization demand to hold upward performed for each historical bar. As a result, I personally convey seldom traded parameterless models, until I buy the farm to interrogation my regime-switching model. That model is nearly parameterless (I left out a few parameters from optimization because of a lack of time, non because of whatever technical difficulties).

The argue backtest optimization tin at in 1 lawsuit hold upward done inside a few minutes is due to my utilization of Alphacet Discovery's server-based optimization engine. There may hold upward other optimization software out at that spot that performs similar functions efficiently -- I welcome comments from the reader.

Statistical Model Predicts A Mccain Victory?

There has been a lot of buzz lately well-nigh a elementary statistical model proposed past times astrophysicists Prof. Gott as well as MD Colley that uses the median polls of each dry reason to predict the Nov electoral vote. (For our un-American readers, the electoral vote is what determines the upshot of a full general election, non the pop vote, inwards instance the nightmarish 2000 election has non already drilled this fact into the world's collective consciousness.)

Dr. Colley has ready a I accept previously applied to the predictive accuracy of political futures marketplace such equally intrade.com. The caveat is this: polls (and futures market) alter amongst time. And at dissimilar times, they predict dissimilar election outcomes. So for example, at this indicate (June 2008), the polls predict a McCain victory, piece the futures marketplace at intrade.com predicts an Obama victory. Who is right?

The answer is: neither. As MD Colley has explained to me, no backtest equally far dorsum equally the June of an election twelvemonth has been conducted. (Their inquiry was based on polls from September onwards.) So nosotros create non know if the June polling prediction has whatever accuracy. Similarly, equally I pointed out before, the futures marketplace tin rank the sack swing violently fifty-fifty on Election Day, fifty-fifty inwards the final hours of an election.

One wages of the Gott as well as Colley method though, is that the predictions resulting from median poll statistics are remarkably stable over time. In 2004, in that location was rattling piffling crusade inwards the electoral stand upwardly for from September through election day. Extrapolating this result, nosotros tin rank the sack live on somewhat to a greater extent than confident of their prediction vs. Intrade.com's, fifty-fifty at this early on date.

And inwards whatever case, I accept observed that the political futures markets are highly mean-reverting, implying that the electrical flow large xx points spread betwixt the Obama as well as McCain futures is destined to decrease inwards the coming months.

As an arbitrage trader, I accept so proceeded to curt the Obama future.

Statistical Electoral Vote Predictor: Update

For readers who convey been tracking the Gott too Colley presidential electoral vote prediction, they volition uncovering a abrupt switch over to a predicted Obama victory inwards the final few days. That is because polls from OH, VA too MO are directly available -- surprising because the iii states are non hitherto known for their Democratic leanings.

It seems to me that, later on all, the stability of prediction at this early on appointment is quite questionable due to the paucity of state polls, a indicate already made past times physician Colley.

Futures Markets Accept No Final Result On Topographic Point Prices

NYTimes columnist too Princeton economist Paul Krugman has previously (see my link here) argued that the trading of stone oil futures should accept no lawsuit on location stone oil prices, reverse to what many politicians too pundits think. Here is his latest elaboration of that argument.

Have Crude Oil Stocks Exhausted Their Run?

Floyd Norris, the primary fiscal correspondent of The New York Times, suggested inward his blog today that nosotros are looking at "The Beginning of the End for High Oil Prices". What is the dry reason of his optimism? He argued that crude oil stocks convey been lagging crude oil prices lately, together with so equity investors must believe that high crude oil prices are causing need devastation which volition eventually cut down crude oil prices together with crude oil companies earnings.

I beg to differ.

Look at the long-standing spread relation betwixt an crude oil stock ETF together with an crude oil commodity ETF, e.g. XLE vs USO, which I convey been commenting on together with tracking since October 2006. At the moment, this spread is inside 1.4 touchstone deviations of its historical value. See my tabular array here (subscription required). In other words, crude oil prices together with crude oil stock prices are at about their long-time historical average. I would hardly telephone telephone that suggestive of the outset of the end.
