Peter Urbani looks at Cornish Fisher and modified VaR as a function of skewness.

Intuition (codified by many models) suggests that investors have to be bribed to accept risk, so that there ought to be a positive link for any given class of security between the amount of risk, and thus the measurement of volatility, on the one hand, and expected return on the other. A puzzle arises, then, from empirical research indicating that “idiosyncratic” volatility, that is, the volatility due to the characteristics of a specific security, is negatively correlated with return once one passes the mid-point of the range of volatility.

The latest version of a yearly analysis tells the same old story about performance, now backed up by fifteen years of data. And the potential rewards of investing with smaller funds go beyond what you see in the database statistics.

By Christopher Faille A new report on hedge fund inflows indicates that the rate at which money is coming into the hedge fund industry reflects that industry’s improved performance, but that if these figures are segmented by strategy or geography, the different rates at which they are attracting money do not very accurately reflect their different [...]

The second in a three-part series on private equity from SEI shows that alpha is a bit slippery these days.

By Christopher Faille Passive and active investments are often contrasted as if the distinction is self-evident. It isn’t. Even for an unambitious long-only equity indexed fund, trades have to be executed in order to maintain the desired balance, and these trades can be executed either well or poorly, in ways that help or hurt the investor. [...]

By Christopher Faille A presentation by Samuel Kunz, chief investment officer of the Policeman’s Annuity and Benefit Fund, Chicago, to the CFA Institute 2011 Asset and Risk Allocation conference addressed the pros and cons of “risk parity.”  His presentation makes it seem that risk-parity portfolios (RPP) and the Capital Asset Pricing Model (CAPM) are sibling rivals. [...]

By Christopher Faille It might be the subject of a Sesame Street episode.  “R is an important letter.  It stands for Rate and Return and Risk-Free and lots of other words!”  Yet, like Oscar the Grouch if deprived of his garbage can, R has lost its fixed abode. Much of the mathematics of finance over the last [...]

By Christopher Faille One of the scariest things about hedge funds is the loss of liquidity that such an investment involves, with lock-up periods, redemption suspensions, wonder about what is in the “side pockets,” and worry about getting caught in the clanging gates.

When academics from other disciplines turn their attention to finance, they sometimes make some quite startling discoveries. These may at first sight seem to resonate with behavioural finance but they are in fact quite different – and this research has not gone unnoticed by some of the most senior central bankers, financial regulators, and legendary hedge fund managers.

By Christopher Faille The press still seems to be discovering “fat tails” and “black swans.”  In July, news outlets gave admiring coverage to the International Monetary Fund’s expression of interest in the ideas of Nassim Taleb, the perhaps-overexposed philosopher who made the phrase “black swan” a cliché upon the success of his 2007 book of that [...]

Professor Neil Johnson talks about the DNA of financial markets with AllAboutAlpha's Vikas Shah

As if there wasn't enough confusion in the roiling U.S. capital markets and regulatory environment, the U.S. Second Circuit Court has issued a decision that will make alpha that more elusive for hedge funds involved in shareholder activism.

Hedge fund assets have bounced back from 2008 to make a new high above two trillion and many performance measures have also more than recovered their losses. Yet it seems most of the inflows are being hogged by the Billionaire's Club, despite studies shouting "Small is Beautiful."

A CMRA/IAFE study of the AXA Rosenberg case shows that model risk may not be on the radar screens of many quant funds.

The European Central Bank’s latest regular financial stability review uses the word “normalisation” a lot. But what does that mean?

Nobody seriously thinks hedge fund returns have a normal distribution, so why does old fashioned optimization continue to dictate portfolio construction? Just as prisms in lenses are used to correct some eye defects, do allocators need to look through more statistical windows?

Managed futures and hedge funds aren't exactly best friends, but a new report suggests investors should have the two together as a way to generate alpha the next time a black swan shows up.

A new study finds that the downside to providing position-level transparency (to some investors at least) is basically zero. Good news if you're a hedge fund offering managed accounts.

It's tough to find a benchmark that fits snugly but doesn't cause blisters.

Some types of alpha have a sting in the tail: they hibernate or head south when tail risks appear, while other types of alpha thrive on panics. Crisis alpha is about celebrating low Sharpe ratios, and looking beyond price volatility to gauge risk.

The arbiters of quality investment reporting have released a new set of draft guidelines of hedge fund managers. Most of it is simply a restatement of existing guidelines, but some is designed specifically for hedge funds.

For some investors, the hedge fund world is assumed to be riddled with potential land mines and threats of heavy gunfire. Which is why finding managers who stick to the "Green Zone" is good practice, according to a new white paper.

A new study of stocks with high hedge fund ownership claims that something fishy is going on at the end of every month.

What the Dickens?! Although financial bubbles look pretty similar on the outside, it turns out that they may be more like snowflakes: no two are the same.

Do hedge funds really care about being the "best"?

A recent academic paper takes issue with the common view of what drawdowns mean for hedge fund performance.

The ubiquitous Sharpe ratio ignores those pesky "higher moments." But evidently, that's not all it lacks.

Hedge fund indexes are often said to contain inherent biases - biases not shared by their investable counterparts. Now, new research sheds light on one source of the divergence between these two types of indexes.

Gone are the days when figuring the crowd affected the pricing and spreads along various parts of the credit market structure. According to a recent report by Standard & Poor's, hedge fund traders and other market participants make measuring credit risk a lot more difficult than it used to be.
