During the last few years, there has been growing interest in the use of factor models for performing risk and exposure analysis of hedge funds. While interpreting directional and spread related factors in this context is fairly straightforward, interpreting non-linear options exposures often is not. Given the variety of activities that can produce options exposures, the interpretation of multi-factor output in this regard can be more of an art than a science. This paper explores the variety of hedge fund manager activities that can drive options exposures in multi-factor analysis.

In its response to the CEIOPS consultation on the preliminary technical specifications for the fourth quantitative impact survey (QIS4), EDHEC argues that the main risk faced by life insurance companies is not taken into account in the standard formula. This risk is that following market (or other significant) losses, a wave of surrenders leaves shareholders bearing the entirety of losses. This is the phenomenon that led to such bankruptcies as that of Executive Life, where losses made public by rating agencies and the media triggered a wave of surrenders and bankruptcy–even though the losses...

In a context of moderate performance in the stock and bond markets in 2007, Funds of Hedge Funds, which are often taken to give an aggregate view of the industry’s performance, returned 10.07% on average for the year, compared to 3.53% for the S&P 500 and 4.14% for the Lehman Global US Treasury Bond index.

This paper studies the temporal variations in the conditional correlations between REIT returns and equity, bond and commodity returns. While REITs are often presented as useful tools for diversification, little is known of the way their returns correlate with the returns of other asset classes over time and in periods of high volatility. This paper addresses this issue and draws two conclusions. First, the correlations between REITs and equity returns rose over the period analyzed, while the correlations with bonds and commodities fell. This indicates to equity portfolio managers that real...

The article studies the temporal variations in the conditional return correlations between commodity futures and traditional asset classes (global stock and fixed-income indices). It reveals that the conditional correlations between commodity futures and S&P500 returns fell over time, a sign that commodity futures have become better tools for strategic asset allocation. The correlations with equity returns also fell in periods of above average volatility in equity markets. We see this as welcome news to long institutional investors as they need the benefits of diversification most in...

As part of its ongoing policy of monitoring asset management practices and comparing them with the results of academic research, the EDHEC Risk and Asset Management Research Centre undertook an in-depth survey of the risk management, portfolio construction, strategic allocation, and performance measurement practices of European asset managers and investors. The EDHEC European Investment Practices Survey is built on a sample of 229 institutional investors and asset managers who, with respect both to the nationality of survey respondents and to the amount of assets under management, are largely...

Recent studies find that a position in at-the-money (ATM) straddles consistently yields losses. This is interpreted as evidence for the non-redundancy of options and as a risk premium for volatility risk. This paper analyses this risk premium in more detail by i) assessing the statistical properties of ATM straddle returns, ii) linking these returns to exogenous factors and iii) analysing the role of straddles in a portfolio context. A revisited version of this paper was published in the Fall 2009 issue of the Journal of Derivatives.

Hull (2007) writes: “For an asset manager the greatest risk is operational risk”. In 2008, however, asset management companies came under severe pressure not from operational risk, but from market risk. What had been seen as an annuity stream that was thought to expose firms to little or no earnings risk turned out to be directional stock market exposure combined with high operational leverage. A revisited version of this working paper was published in the Fall 2010 issue of the Journal of Applied Corporate Finance.

In this paper we analyze the conditions under which the presence of a multiplicative background risk induces a more “prudent” behavior. We show that the results from Kimball (1990) concerning the convexity of the marginal utility are no longer sufficient with multiplicative risk. An agent is multiplicative risk prudent when the coefficient of relative prudence is greater than two. We introduce the concept of quintessence in order to guarantee the decrease of relative temperance. Both decreasing relative prudence and decreasing relative temperance are sufficient to guarantee more “prudent”...

Hedge funds are often referred to as absolute return strategies, yet investors are aware that most hedge funds do in fact take on a variety of systematic and quasi-systematic exposures. If a manager of a fund of hedge funds (FoF) finds that the exposure of the FoF to a certain systematic exposure or the risk level broadly has become excessive, then the FoF manager may want to hedge. The purpose of this article is to outline the major issues involved with overlay hedging in a fund of funds portfolio and to provide relevant solutions to these issues. These include the determination of whether...

This paper develops a capital asset pricing model based on the production side of a monetary economy. Relying on a general version of the standard Real Business Cycle model with cash and credit goods, we find that the factors determining the mean excess returns on financial assets are i) real capital growth, ii) the nominal interest rate and iii) the capital-to-wealth ratio. Our model is parsimonious in that the results rely neither on any particular specification of the production function nor on capital adjustment costs. Empirical evidence gives strong support to the presence of the...

Not all insiders are the same; some are more effective than others in processing the information they have access to, and invest their own wealth accordingly. We used a database with transactions from the U.K. market to identify insiders with superior market timing abilities. For the period 1994 to 2006 we showed that informative insider trades can be identified ex ante through certain characteristics of the transactions and the firm itself. Moreover, we showed how outsiders could benefit from this information.

The EDHEC Risk and Asset Management Research Centre has released a new survey that is drawn from its research programme in asset allocation and alternative diversification. This programme has led to extensive research on the benefits, risks, and integration methods of alternative classes and instruments in asset allocation.

Fund ratings are a widely used tool for fund promoters and fund subscribers. They serve to evaluate fund performance on a risk and return basis in an easily understandable way, and allow the performance of different funds to be compared. In this context, the quality and the robustness of the ratings is a critical subject for both investment management firms and investors. Though the predictive capability of fund ratings has not been proved, numerous studies performed on US mutual funds have concluded that fund subscribers are widely influenced by fund ratings in making their choice. A...

This paper investigates why traders hide their orders and how other traders respond to hidden depth. Using a logit model, the authors provide empirical findings suggesting that traders use hidden orders to manage both exposure risk and picking off risk. Using probit models, they show that hidden depth increases order aggressiveness. The authors' interpretation of this empirical evidence is threefold. First, hidden depth detection is possible and frequent. Second, when traders detect hidden volume at the best opposite quote, they strategically adjust their order submission to seize the...

The article looks at the performance of 56 momentum and contrarian strategies in commodity futures markets. The authors build on the research of Erb and Harvey (2006) who focus on one momentum strategy. While contrarian strategies do not work, 13 momentum strategies are found to be profitable in commodity futures markets over horizons that range from 1 to 12 months. A revisited version of this paper was published in the June 2007 issue of the Journal of Banking and Finance.

A recent publication by the EDHEC Risk and Asset Management Research Centre has drawn conclusions that highlight the shortcomings of well known capitalisation- or price-weighted stock market indices and argues that the choice of benchmark for asset allocation or performance measurement is a task requiring particular care. In a call for reactions to this publication, EDHEC finds that the answers of the more than eighty respondents (asset management firms, pension funds, insurance companies, private banks, etc.) tend to reinforce the conclusions drawn by the original publication. Although it...

European leaders, eager for an explanation absolving them of responsibility, have once again laid blame on the seemingly detrimental role played by hedge funds in this summer’s crisis. This crisis is the result of a sudden fall in asset prices, combined with increased aversion to risk on the part of investors. To suggest that hedge funds are to blame for this crisis is simplistic but tempting, as their speculative, unregulated, and opaque nature make them easy targets - all the while, more delicate market and regulatory issues are avoided. So, as a counterpoint to these accusations that often...

This paper compares a number of different approaches for determining the Value at Risk (VaR) and Expected Shortfall (ES) of hedge fund investment strategies. The authors compute VaR and ES through completely model-free methods, as well as through mean/variance and distribution model-based methods. Among the models considered certain specifications can technically address autocorrelation, asymmetry, fat tails, and time-varying variances which are typical characteristics of hedge fund returns. They find that conditional mean/variance models coupled with appropriate distributional assumptions...

In a reply to the CESR Issues Paper on the eligibility of hedge fund indices for the purpose of UCITS, the EDHEC Risk and Asset Management Research Centre argues that hedge fund indices should not be required to offer more controls and more transparency than existing financial indices such as stock market indices. Likewise, their construction should not be subjected to detailed rules for choosing constituents and implementing rebalancing and weighting mechanisms.

Hedge fund indices have been criticised for a lack of representativity and for their biases, to the point that serious doubts about the usefulness of hedge fund indices have been raised by investors and regulators. This paper examines whether the problems that are outlined for hedge fund indices also exist for other indices that seem to be widely accepted. The drawbacks of hedge fund indices pointed out in the literature do indeed exist. However, in this paper, the authors point out that there are possible solutions to these problems. A revisited version of this paper was published in the...

Many investors do not know with certainty when their portfolio will be liquidated. Should their portfolio selection be influenced by the uncertainty of exit time? In order to answer this question, we consider a suitable extension of the familiar optimal investment problem of Merton (1971), where we allow the conditional distribution function of an agent’s time horizon to be stochastic and correlated to returns on risky securities. In contrast to existing literature, which has focused on an independent time horizon, we show that the portfolio decision is affected. A revisited version of this...

This brief article suggests three approaches for how to benefit from structural opportunities in the commodity markets, drawing from the recently published book, “Intelligent Commodity Investing.” The author notes how over long time horizons, the term structure of a commodity futures curve becomes the dominant driver of return for individual futures contracts. For shorter time horizon opportunities, the author discusses mean-reverting commodity spread trades that have approximately seasonal frequencies.

On September 18th, 2006, market participants were made aware of a large hedge fund’s distress. On that date, Nick Maounis, the founder of Amaranth Advisors, LLC, had issued a letter to his investors, informing them that the fund had lost an estimated 50% of their assets month-to-date. By the end of September 2006, these losses amounted to $6.6-billion, making Amaranth’s collapse the largest hedge-fund debacle to have thus far occurred. There were (and are) many surprising aspects of this debacle. A revisited version of this paper was published in the Spring 2008 issue of the Journal of...

Several studies have put forward that hedge fund returns exhibit a non-linear relationship with equity market returns, captured either through constructed portfolios of traded options or piece-wise linear regressions. This paper provides a statistical methodology to unveil such non-linear features with the returns on any selected benchmark index. It estimate a portfolio of options that best approximates the returns of a given hedge fund, accounts for this search in the statistical testing of the contingent claim features, and tests whether the identifed non-linear features have a positive...

In the last decade, economists have produced a considerable body of research suggesting that the historical origin of a country's laws is highly correlated with a broad range of its legal rules and regulations, as well as with economic outcomes. This paper summarizes this evidence and attempts a unified interpretation. It also addresses several objections to the empirical claim that legal origins matter. Finally, it assesses the implications of this research for economic reform. A revisited version of this paper was published in the June 2008 issue of the Journal of Economic Literature.

The relevance of the information ratio and the alpha, two leading performance measures for multi-index models, depends on the type of portfolio held by investors. This paper compares these measures with the generalized treynor ratio (GTR) on the quality of the rankings they produce. A precise measure yields similar rankings with alternative benchmarks. A revisited version of this paper was published in the Summer 2007 issue of the Journal of Portfolio Management.

In this study, EDHEC-Risk Institute, while recognising that the directive allows the conditions in which investment companies can operate on the regulated markets or over-the-counter to be harmonised, warns of the eventual adverse effects relating to the obligation of transparency for systematic "internalisers" and the obligation of "best execution". The authors find, in the case of the obligation imposed on systematic “internalisers” to maintain a public spread of prices, that it is prejudicial for this restriction to be removed for the least liquid securities. This provision will lead, in a...

This paper examines the role of non-normality risks in explaining the momentum puzzle of equity returns. It shows that momentum returns are not normally distributed. About 70 basis points of the annual momentum profits can be attributed to systematic skewness risk. This finding is pervasive across nine strategies and is reinforced when time dependencies in abnormal returns and risks are explicitly modeled. The analysis also reveals that the market and skewness risks of momentum portfolios evolve over the business cycle in a manner that is consistent with market timing and risk aversion. A...
