Summer of 1000 Posts: CAPM/ Alpha Theory

August 9th, 2009 | Filed under: AAA Newsreels, Featured Post, Today's Post

CAPMToday, we bring you another installment of our “Summer of 1,000 posts” (more…)

This week we’ll be looking back through our archives to cull posts on the topic of CAPM/Alpha Theory…

How Hollywood, lotteries and mutual funds show that all risk is relative
Since the birth of the CAPM, empirical evidence has been uncooperative – showing that high risk investments produce lower returns, not higher ones.  Now one author looks beyond equity markets and finds even more evidence against the vaunted CAPM.

Real Estate Alpha
A lot of research has been conducted on real estate mutual funds.  But precious little has ever been conducted on the alpha produced by institutional funds that invest in commercial real estate – until now…

Crowds may not be so “wise” after all
A new book, an industry survey, and media reports have propelled the age-old topic of market efficiency into the spotlight this month.

Study hints that alpha may be finite (at least in the short term)
Is it a coincidence that hedge fund returns are exploding right after the biggest culling in the industry’s history?

…3.96% per annum

August 5th, 2009 | Filed under: Performance, Analytics & Metrics, Today's Post

answerYesterday, we covered the first half of an interesting academic study on hedge fund redemption terms.  We learned that the auto-correlation of monthly returns was positively related to the actual redemption terms of a fund.  Today, we cover the second half of this paper by MIT’s Amir Khandani and Andrew Lo – in which the duo estimate an actual premium associated with redemption terms.

Rather than comparing actual redemption terms to see if illiquid funds perform better than liquid ones, the duo can now compare autocorrelation to (risk adjusted) returns.  In the table from their paper reproduced below, they create 5 separate hypothetical portfolios based on autocorrelation buckets (click to enlarge).  Lo and behold (pardon the pun), the funds with the highest autocorrelation of returns generally also had the highest risk-adjusted returns.

autocorr2

Note that while  high auto-correlation is generally associated with higher risk-adjusted returns, there are some exceptions.  In particular, Khandani and Lo highlight the fact that the Global Macro funds with the highest auto-correlation (lowest liquidity) actually posted below average results.  Also, we noted that very few of the relationships were monotonic (with the best performing funds of funds, for example, being the ones with the second lowest autocorrelation).

Okay.  So you read yesterday’s post and you get the idea above.  But so what, right?

Can HF return autocorrelation actually predict how easy it will be to eventually redeem?

August 4th, 2009 | Filed under: Performance, Analytics & Metrics, Today's Post

withdrawalIf one word could sum up the multi-dimensional train wreck we’ve seen in financial markets over the past few years, it might be liquidity.  Illiquidity-driven death spirals have affected individual hedge funds, liquidity “mismatches” have hurt funds of funds and university endowments, which had long benefited from an “illiquidity premium” recently came crashing back to earth (see this recent Vanity Fair article for a great example).

Several experts have contemplated the value of liquidity on these pages.  Some have even suggested that hedge funds owe much of their “alpha” returns to illiquidity, not skill.

But what exactly is this illiquidity premium and how do you even begin to measure “illiquidity”?  You could, for example, look at the bid/ask spread.  Or, you could look at the “metrics such as the “percent of day’s-trading-volume”.  Or in the case of managed or structured vehicles, you could simply find out the redemption terms.

Each of these techniques presents complexities when applied to hedge funds, however.  But academics use a technique that might save a lot of time for those trying to measure the illiquidity of hedge funds: return autocorrelation.  The serial correlation between monthly returns can reveal a lot about the actual illiquidity of a fund according to a study by MIT’s Amir Khandani and the absurdly prolific Andrew Lo, his MIT colleague.

In “Illiquidity Premia in Asset Returns: An Empirical Analysis of Hedge Funds, Mutual Funds, and U.S. Equity Portfolio“, Lo and Khandani prove that hedge fund return autocorrelation is a proxy for actual redemption terms.  In their words:

Newsreel: Rebounds, social markets, Saskatchewan and the “Triple Lindy”

July 20th, 2009 | Filed under: AAA Newsreels, Today's Post

Canola payola?

E.M.H. R.I.P. W.T.F?

In an ironic twist, the Economist suggests that financial engineering (and by extension the hedge funds built with its outputs) are built on the shoulders of the efficient market hypothesis.  Yet the much ballyhooed demise of the EMH should, in theory, pave the way for skill-based, alpha-centric returns.  In fact, the newspaper even makes the case for hedge funds in this weeks edition:

“…In 1980 Sanford Grossman and Joseph Stiglitz, another subsequent winner of a Nobel prize, pointed out a paradox. If prices reflect all information, then there is no gain from going to the trouble of gathering it, so no one will. A little inefficiency is necessary to give informed investors an incentive to drive prices towards efficiency…”

Confirmation that fund of funds investment is a trailing indicator

Hedge Funds Review reports on S&P’s latest fund of funds asset flow data, observing that “…Investors quick to respond to disappointing returns have been much slower to react to improving performance.”

Is new 130/30 ETF active or passive?

While it’s originators, Andrew Lo and Pankaj Patel call it a “passive” strategy, the model upon which the new Proshares 130/30 ETF is built looks a lot different that a typical passive index.   Says Lo: “The quantitative model behind our 130/30 Large-Cap index is based on extensive, robust research on the real-world factors contributing to stock performance.”

(btw,did you know Lo’s first science project was to make a battery out of a lemon.  Amazing but true.)

When is a rebound not actually a rebound?

Summer of 1000 Posts: Alternative Beta and Hedge Fund Replication

July 12th, 2009 | Filed under: Featured Post, Today's Post

Today, we bring you another installment of our “Summer of 1,000 posts” (more…)

This week’s sampling from our archives covers the topic of Alternative Beta and and Hedge Fund Replication…

With hedge funds back in the black, how are the hedge fund “clones” doing?
At least one hedge fund “replicator” has recently been replicating the aspirations, if not the actual experiences of hedge fund managers.

A novel approach to monitoring daily HF returns when they don’t actually exist
Hedge fund replication is now put to a different use by researchers.  Call it “assisted hedge fund replication”.

Pendulum swinging back to investable hedge fund indices for passive HF exposure
It wasn’t long ago that investors were graduating from simple investable hedge fund indices to more sophisticated hedge fund replication products for their passive hedge fund exposure.  Now, it seems that “simple” is back as some investors are willing to stomach the high hedge fund fees in exchange for transparency and liquidity.

Summer of 1,000 Posts

June 28th, 2009 | Filed under: Featured Post, Today's Post

This week marks the publishing of our 1,000th post at AllAboutAlpha.com.  We’ve seen a lot over the past 3 years.  And despite its recent travails, the hedge fund industry remains approximately the same size now as it was back when we thought WordPress was a new type of laser printer and that blogs – like Pet Rocks and Cabbage Patch Kids before them – were another sign of the End of Times.

To celebrate this milestone, we thought we would highlight some popular posts in each topic area covered by AllAboutAlpha.com.  So throughout the summer, we’ll be pouring through the archives so you don’t have to.

(If you are a paying subscriber or a member of the CAIA Association and can’t remember your password, just hit “forgot password” at the right and we’ll have one of our army of overworked interns send you an email.)

This week, we’ll start with one of our favorite topics at AAA – CAPM/Alpha Theory.

“Beta blockers” aim to reduce the blood pressure of those facing hedge fund gates

June 7th, 2009 | Filed under: Portable Alpha & Alpha/Beta Separation, Today's Post

Linear regression models (a.k.a. factor models) have a number of emerging applications in the hedge fund industry.  One of the most often-cited here and elsewhere is hedge fund replication (see related posts).  But as we discovered recently, regression-based models can also be used to estimate the daily returns occurring between monthly hedge fund reporting cycles (see related post).  In addition, MIT’s Andrew Lo has proposed several other applications of linear factors models to address situations such as transitioning between managers and portfolio rebalancing for risk management purposes (see related post).

Now Lo has teamed up with Alexander Healy of Alpha Simplex Group (the company with which Lo is closely affiliated) and proposed yet another application of this truly alpha-centric approach to portfolio management: dealing with redemption gates.

The two suggest that when hedge fund investors are confronted with redemption gates, they can essentially remove their economic exposure to many of the underlying hedge fund betas in much the same way an executive can monetize un-vested stock options.  By basically shorting the basket of betas that make up the returns of lock-up hedge fund allocations, investors can reduce volatility dramatically and in some cases, even increase returns (i.e., if the alternative betas in question temporarily deliver negative risk premia).

Drawing on a knack for colourful metaphors, Lo says this is not unlike the strategy taken by the drugs often prescribed to those with high blood pressure:

San Francisco Day Two: President Lo’s cabinet, redemption gates and weird stuff in the Canadian water supply

May 13th, 2009 | Filed under: Today's Post

Much of today’s discussion at this “no-media” event in San Francisco centred around what, if anything, the United States can learn from the Japanese “lost decade” after that country’s economy crashed in the 1990’s.

The world’s foremost authority on that topic is probably Richard Koo, the author of The Holy Grail of Macroeconomics: Lessons from Japan’s Great Recession.   Koo is an engaging speaker who has the ear of economic leaders around the world.  His thesis is that in a “balance sheet” recession, private sector balance sheets take a bath and the private sector starts to save.  This, coupled with slower growth, leaves a hole in GDP you could drive a Mitsubishi truck through. The solution, says Koo, is to shore up lost GDP with government spending.  While it sounds like basic Keynesian economics, Koo’s take is that debt is better diverted from private sector balance sheets to public sector ones where its existence won’t necessarily lead to pulling in the spending reigns.  Once the private sector balance sheets are cleaned up, Koo argues that governments can dispose of their debt in a more orderly fashion.

But wait, won’t ballooning government spending lead to inflation?  Not so, says Koo.  He points to Japan’s low inflation rate – achieved in the midst of one of the world’s worst debt to GDP ratios.

San Francisco: Hedge fund “green shoots” among many surviving trees

May 12th, 2009 | Filed under: Today's Post

We hear a lot about “green shoots” in the economy.  From recent unemployment data to Bank of America’s Q1 results to a bottoming-out of home prices, the media is beginning to report on so-called “hopeful signs of life.”  Even the hedge fund industry is getting in on the game with solid April performance, stabilizing AUM and a “re-un-coupling” of returns from equity markets (after appearing to be attached at the hip in the fall).

But the analogy of green shoots after a harsh winter may not be the best for the hedge fund industry based on the comments from several speakers here in San Francisco at this “no-media” gathering of funds and institutional investors this week.  It’s almost as if a forest fire might be a better analogy.

As a teenager, my father spent summers as a forest ranger in Northern Ontario (not far from Timmins, childhood home of Myron Scholes).  As residents of Northern Ontario can attest, fire is devastating to humans, but is often a natural part of the forest ecosystem.  Without it, brush can build up over the years, causing Santa Barbara-sized headaches.   But with it, weaker trees die, providing more access to sunlight for their stronger surviving brethren.  To be sure, those survivors also get scorched and lose their needles.  But they soon recover; relying on the cleansing effect of forest fires to “re-set” the forest ecosystem and set the stage for future growth.

Book Review: The Heretics of Finance – Conversations with Leading Practitioners of Technical Analysis

April 5th, 2009 | Filed under: Guest Posts, Today's Post

Special to AllAboutAlpha.com by: James Burron, CAIA, ICICI Wealth Management Inc.

Ever heard of Peter Lynch, Warren Buffett or Benjamin Graham?  Sure.  But how about Robert Farrell, Alan Shaw or Stan Weinstein?  Chances are many investors have heard of most or all of members of the first group and none of the second.  What’s the difference?  Lynch, Buffett and Graham are fundamental (research) investors; Farrell, Shaw and Weinstein are technical adherents.

The striking part of reading The Heretics of Finance (Andrew Lo & Jasmina Hasanhodzic, Bloomberg Press, 2009) was that upon opening it up to the table of contents, I could only find one interviewee I recognized (Laszlo Birinyi Jr., if you were wondering – and only because he was often on Wall Street Week). This made me think: was I missing out on something, or was technical analysis really just a rather obscure investment style more akin to astrology?

I tried to keep an open mind as I readied myself for talk of head & shoulders (not the shampoo), double and triple tops, pennants (whatever those are) and breakouts.  I’ll admit to being a somewhat of a skeptic of technical analysis.  But as I read Heretics, I gained an appreciation for what drives these highly intelligent – if not quirky – individuals.

Newsreel: Kitzbuhel, talent for a song, hand-me-down hedge funds, and mending lending

March 26th, 2009 | Filed under: AAA Newsreels, Today's Post

Double Black Diamond:

How bad was 2008’s decline in hedge fund assets under management?  According to the chart below from Pensions & Investments, it was somewhere between a single black diamond run and the storied Hahnenkamm at Kitzbuhel.  Still, this only puts the industry back to mid-2006 – hardly the very bottom of the slope (and not remembered as a particularly horrendous year for the industry).

But the bottom of this particular run may be near.  According to some pundits, we should know which scenario above is playing out pretty soon (the “Bullish”, “Base”, or “Bearish” case).  The head of hedge fund firm Thames River Capital told a conference audience recently that he thought the shakeout would end in June.  MIT’s Andrew Lo also suggests the same.  But other industry players say right month, but wrong year.  In any event, the head of UBS prime brokerage services says:

A graphical look at hedge fund leverage

March 5th, 2009 | Filed under: Featured Post, Today's Post

Britain’s Financial Services Authority (FSA) recently found that hedge fund leverage was nearly extinct (for now).  In what is billed by the FT as the “only authoritative data on the opaque industry”, the FSA found that the average hedge fund had leverage of 1.15x, down from about 2x a year ago and 1.44x as late as last spring.  According to the FT, the FSA defined leverage as long positions over NAV, “ignoring short positions.”

But what happens when you account for shorts?  Regular readers may remember the chart below left from a recent European Central Bank report (see post).  The ECB reported gross leverage (longs plus absolute value of shorts) from Hennessee Group and found leverage levels around 1.5x.  (To compare to the FSA’s estimate, note that longs over NAV was under 1.0 – likely due to the fact that only lower-leveraged long/short equity funds were counted.)  This seemed to back up what managers were telling Merrill Lynch in a survey cited by the ECB (right panel) – that a majority of managers were actually using no leverage at all.

Battle of the Quants III: Blow-by-blow

February 5th, 2009 | Filed under: Today's Post

We have moved the cast and crew of AllAboutAlpha.com down the street today from the Metropolitan Club to cover the “Battle of the Quants III“, an increasingly popular event that attracts both financial rocket scientists and mere mortals like your humble scribe.

Ray Kurzweil is billed by Wikipedia as an “inventor and futurist”.  And they’re not making it up.  He invented one of the first music synthesizers, the first flat-bed scanners and the first speech recognition software and has been recognized by three US Presidents, has written 4 best selling books and has several honorary doctorates to his name.  He also runs what he calls “a high frequency quant fund”.  He addressed the crowd of 100 on the topic of “accelerating pace of change” and “21st Century Technology and financial markets”.

Kurzweil is also well known for his views on “technological singularity” – the increasing frequency of so-called “Paradigm Shifts” over the past billion years and the ensuing exponential growth of information technologies.

On technological advancement: “Health and medicine is now an information technology.  The Human Genome is the software.  Now health – like other information technology – will begin to advance exponentially.”

On faxing physical objects: “In the future everything will be an information technology.  Someday, we’ll

Exclusive results from our second annual 130/30 poll: Despite recent distractions, underlying interest remains

November 18th, 2008 | Filed under: 130/30, Today's Post

Thank you to those who participated in this year’s AllAboutAlpha/Terrapinn 130/30 poll.  Despite being distracted by market events of the past month, response rates were largely the same as last year across most categories and geographies.  We just finished re-counting the “pregnant” and “hanging” chads last week and can now provide you with the results.

Before we dive into the highlights below, the usual caveats should be issued.  Like last year’s survey, the respondents to this year’s edition are 100% self-selected.  As a result, they may likely be biased toward 130/30 investing already.  On the other hand, this was also the case last year.  So comparisons between the two polls may still be somewhat instructive.

Demographics

To fully understand the results, it’s helpful to quickly tell you about the broad demographics of the 100+ respondents.  Asset managers comprised a larger proportion of this year’s respondents due to a drop in the number of end investors filling out the survey.

This drop could be a result of the recent market calamities (filling out online surveys may not be at the top of most investors’ priority lists right now), or it could mean that investors are just not into 130/30.  However, analysis of the (smaller) sample of investors suggests that interest remains significant.

Response was also higher from North America and Europe than it was last year. This may have simply been a result of the particularly mailing list used to alert people about the survey.

AllAboutAlpha Exclusive: An interview with one of the witnesses called to testify at the Congressional hedge fund hearings this week

November 13th, 2008 | Filed under: Featured Post, Today's Post

Last summer, we told you about an academic article on hedge fund regulation by Houman Shadab of George Mason University, just outside of Washington D.C.   Shadab’s cogent and balanced analysis of hedge fund regulation stood in stark contrast to calls to prevent most investors from purchasing hedge funds.  He argued that “financial sophistication” and wealth level are not synonymous and that wealth-based investing limits actually hurt, not helped, most truly “sophisticated” investors.

Today (Thursday) Shadab testified in front of the US Congress’ Committee on Oversight and Government Reform along with George Soros, Ken Griffin, John Paulson, Andrew Lo, Jim Simons and other hedge fund industry participants.

Anyone involved with the hedge fund industry needs to read Shadab’s written testimony or watch the video of his verbal remarks.  He has brought together over two years of research to address a variety of topical issues such as the extent to which hedge funds were actually involved with CDSs and CDOs, systemic risk and even hedge fund compensation.  We’d also recommend you check out his working paper to be published next year in the Berkeley Business Law Journal called “The Law and Economics of Hedge Funds: Financial Innovation and Investor Protection” (available here).

We spoke with Shadab after the hearing today and asked him to elaborate on a few of the points raised in his testimony.

AAA: As you pointed out in your testimony, hurdle rates and high water marks act as a governor on manager compensation – a feature that traditional executive compensation schemes may lack. But isn’t a performance fee still asymmetrical in the manager’s favor?  Or is that even a problem?

Shadab: Given how competitive the hedge fund industry is, I’m not sure the asymmetric nature of the performance fee is a problem. There is strong pressure on managers to deliver results satisfactory for investors, meaning: perhaps managers’ greatest incentive to strike the right balance between risk-taking and risk management is preventing investor redemptions down the road.  As we are currently witnessing, hedge fund investors aren’t satisfied to simply do less bad than the market. If the hedge fund manager can’t weather the storm, redemptions will follow.

AAA: Did hedge funds start (or at least act as a catalyst for) the mortgage crisis?

Shadab: Hedge funds only started really investing in securities whose value was in some way related to mortgages by sometime in 2004, according to the numbers I have seen. By that time, the housing bubble was in full swing, and interest rates were quite low by historical standards. Even when hedge funds did arrive on the mortgage-related security scene, they limited themselves primarily to the equity tranche, or riskiest slice, of security issued in a typical collateralized debt obligation deal. This type of activity didn’t fuel the credit crisis, since the primary purpose of such deals to get investment grade tranches issued that paid higher yields than bonds having same rating. It was pensions, money market funds, insurance companies, and banks fueling these deals, not hedge funds.

AAA: You describe short sellers as “watch dogs” over public companies. But is it possible for these watch dogs to ever bite their owners?   In other words, have short sellers ever caused a company to fail?

Shadab: I have not read about a case where an otherwise healthy company was forced into bankruptcy merely because their stock was repeatedly sold short. Remember, its not like short-selling has the power to move stocks, at least not without massive fraud in the form of abusive naked shorting. Short-selling by itself riskier than going long, because the short-seller will have to cover at some point, which could in principle cause far more losses than the initial investment. And if a trader keeps shorting a healthy company, they keep exposing themselves to more risk: the farther a stock drops, the higher it could potentially come back, which would be ruinous for a short-seller.

AAA: In your view, what are regulators’ top 3 biggest misconceptions about hedge funds?

Shadab: One: Hedge funds are “risky.” Risk is the most important concept in all of finance. Unfortunately, its one of those concepts used far more than its understood. Regulators think that hedge funds are risky because they’re non-traditional. But traditional, long only buy-and-hold investments are more risky, because, as we all should know, they are undiversified, not with respect to companies in which they invest, but with respect to strategy.  Hedge funds’ non-traditional investment strategies are less risky, at least in principle, because they do not necessarily commit the manager to one single way of making gains for investors, and one way of thinking about markets. When viewed from the perspective to outcomes, and not hypotheticals, hedge funds are less risky than traditional investments.

Two: Transparency will reduce risk. Too many seem to believe that hedge funds can simply disclose their leverage and investment positions, and from that information we will know all we need to know about the risks that hedge funds pose. That’s just too simplistic. To get an accurate picture of hedge fund risk, we would need confidential information from virtually every financial institution, and on a daily basis, at least. Two questions arise: what regulator has the expertise to process that information? and what is the appropriate response to discovering that a fund or group of funds has a risk exposure deemed too great?  It’s just not clear that regulators will have sufficient manpower and expertise in finance to make sound judgments about what risks hedge funds pose, to whom, to what extent, when, and what should be done when the response itself could cause a financial disruption. I worry that increasing transparency will decrease due diligence, and lull parties into complacency. This financial crisis is partially a crisis of complacency: too many parties relied on ratings agencies to evaluate credit risk, and the Securities and Exchange Commission to keep an eye on investment banks. It would be a shame if hedge fund investors, prime brokers, counterparties, or creditors began to relax their oversight and instead relied upon, for example, the Federal Reserve to make calls about which funds are too risky. If anything, we need more market discipline, not the opposite.  The solution, however, is not to “do nothing.” Rather, policymakers should look at some of the underlying causes of assets bubbles, such as monetary policy, bank supervision and capital requirements, off balance-sheet and mark-to-market accounting, the power of ratings agencies in credit markets, and how restrictions permitting mutual funds to pursue alternative investments may bring additional volatility-dampening strategies to markets.

Three: Hedge funds are “highly leveraged”: Although many hedge funds do employ large amounts of leverage, as high as 10 or 15 to 1, high leverage is not a defining feature of hedge fund industry. The latest estimation I have found is that hedge funds in 2007 were leveraged up to 3.9 times assets, and this includes all types of leverage, whether from borrowings or through shorting or derivatives exposure. Indeed, hedge fund leverage seems to primarily come from using derivatives, not borrowings. I think that is important, because leverage obtained through derivatives seems to be of the type that is used to reduce and manage risk, not increase it.

AAA: You warn that “changing how hedge funds are regulated could actually undermine the interests of investors and increase economic instability.” Can you give us an example of a form of regulation that has the potential to do this? If hedge funds have nothing to hide, why do they resist regulation?

Shadab: Hedge funds don’t have anything to hide, but certainly do have something to protect: their intellectual property, in the form of investment positions and trading strategies. This is not to say that every hedge fund manager is sitting on the equivalent of the formula to Coca-Cola. Many hedge fund investment strategies are in fact quite mundane, and investors must be sure they are paying their manager for genuine value.  So, for example, by employing leverage to benefit from very small spreads between two different debt instruments, a fixed-income arbitrage hedge fund can help all market participants realize the true credit risks to which they are exposed. In this sense, hedge funds reduce bad surprises for other parties.  Now, if limitations on leverage are placed upon hedge funds, the ability of such funds to make these types of revelations to the marketplace–so that others can make  better investment decisions that relate to credit quality–may be hampered.

AAA: If you’ll permit me to ask a self-interested question, I see you cited AllAboutAlpha.com in your written testimony.  How long have you been a reader?  Why do you read it?

Shadab: How long? Not long enough! It’s now my one-stop-shop for keeping up on the developments and ideas driving the world of hedge funds.

AAA: That’s great to hear.  Thank you for your time.

There are plenty more observations and statistics in the 26-page paper Shadab submitted to the committee yesterday.  Let’s hope that this type of dispassionate discussion catches on as regulators perform the post mortum on the recent financial chaos.  (Note to Italian and German hedge fund managers fighting for their regulatory lives: Shadab’s contact information is on his website…)
