Hedge Funds: Myths and Limits
Click to Enlarge
  In a little more than a decade, hedge funds have ceased being institutions understood only by specialists, though popularly credited with the capacity to wreak occasional havoc in financial markets, and are gradually assuming the position (through funds of hedge funds) of vehicles for retail investment. The books reviewed here have different aims. That of de Brouwer is concerned with broader issues of public policy raised by the behaviour of hedge funds, and draws on experience acquired as part of his membership of the Study Group on Market Dynamics, which reported to the Financial Stability Forum's Working Group on Highly Leveraged Institutions set up in the aftermath of the Asian financial crisis and the rescue orchestrated by the United States Federal Reserve of the hedge fund, Long-Term Capital Management (LTCM).Lhabitant's book, by contrast, belongs to the more abundant line of books oriented primarily towards practitioners. Early books of this kind, often by authors with close connections to the industry as advisers or investment managers, tended to be largely descriptive and anecdotal, though they often succeeded in transmitting a good feel for their subject[1]. Lhabitant is more ambitious and, in addition to reviewing the institutional
structures and strategies of hedge funds, regulations governing their relations with investors, transactions employed by hedge funds, and information available concerning hedge funds, deploys in an accessible way more technical academic research, including his own, in his discussion of asset allocation and performance measurement.

Definition and origins

De Brouwer and Lhabitant devote considerable attention to the issue of definition. Both locate hedge funds' origin in the private investment partnership set up at the end of the 1940s by Alfred Winslow Jones, which aimed to generate profits with reduced market risk by combining long positions in undervalued stocks with short positions in overvalued ones. But both describe the difficulty of arriving at a precise definition sufficiently inclusive to cover all the institutions and strategies usually covered under the term,"hedge fund". Definitions which are mentioned in their books include the flexible and serviceable one of Goldman Sachs and Financial Risk Management:

"The term 'hedge fund' is historically rooted and has evolved over time to include a multitude of skill-based investment strategies with a broad range of risk and return objectives. The common element among these strategies is the use of investment and management skills to seek positive returns regardless of market direction."

The fee structures of the funds reflect this objective with the result that a low or zero return reduces fees correspondingly and higher returns lead to higher fees, the incentive part typically being in the range of 15-25 per cent of annual realised performance.

This looser definition brings out similarities between hedge funds and certain categories of investment companies in earlier periods. As Nicholas notes in the manual cited above, the lineage of hedge strategies used by hedge funds today, particularly those involving arbitrage and hedging, stretches back to those of the celebrated investor and writer on security analysis, Benjamin Graham, as early as the 1920s[2]. Indeed, in his celebrated popular treatise on investing, The Intelligent Investor, Graham notes that the operations of the Graham-Newman Corporation during its life from 1926-1956 included merger arbitrages and "related hedges", namely, the purchase of convertible bonds or preferred shares and the simultaneous sale of the common stock into which they were exchangeable, both of which are included among hedge-fund strategies (for example, among those discussed by Lhabitant[3]). The definition of Goldman Sachs and Financial Risk Management accommodates several features of the operations of proprietary trading desks of banks, investment firms and insurance companies as well as of hedge funds (though, as de Brouwer notes, certain important constraints on aggressiveness in trading such as the use of leverage tend to be less binding for the latter). The difficulty of clearly distinguishing hedge funds from other institutions carrying out similar operations explains the now current use of the term, "highly leveraged institution" (HLI), in discussion of regulation and the focus of such discussion on transactions, applicable jurisdictions, balance sheets and transparency rather than on the type of firm.

Structures, operations and strategies

Unsurprisingly in view of his focus on the role of hedge funds in Asia, under the heading of strategies de Brouwer devotes special attention to macro hedge funds whose operations involve assessment of countries' macroeconomic indicators in order to profit from imbalances in exchange rates, bond yields and short-term interest rates, and the prices of asset classes. For his part Lhabitant not only ranges at greater length over the different major strategies pursued by hedge funds but also gives a good concise account of their structures including one of the key relationship with prime brokers, the major investment banks which clear the funds' trades, act as their custodians, provide the margin financing essential to their leverage, and lend the securities required for taking short positions. His review of strategies benefits from lucid descriptions of the transactional techniques such as the use of derivatives which hedge funds employ. In boxes in the text he also discusses a number of cases which exemplify various points. But for extended profiles of the often unusual or eccentric personalities among hedge funds' founders and managers fuller sources are the writings of financial journalists which also illustrate the risks and rewards of the different strategies historically followed by hedge funds[4].

Asset allocation and performance
Both authors provide overviews of the industry's performance. But as is appropriate for a book intended to guide investors, Lhabitant's coverage is much more extensive and includes a survey of hedge-fund indices and research providers together with some useful observations on various statistical biases to which the data are subject[5]. Lhabitant's review of hedge funds' performance leads naturally to his treatment of investing in hedge funds including through funds of hedge funds. Here Lhabitant dwells on limitations of the conventional approach to portfolio selection based on means and variances of returns as applied to hedge funds. Some of his points are technical such as the ways in which variances of investment returns are affected by hedging through derivatives. But scattered through his discussion are a number of more general critical observations on the tendency to to give too much emphasis to the statistical measure of risk as variance/volatilty of returns. Only in his annex on statistical techniques useful in analysing hedge funds' performance does he bring his concerns on this subject together when he writes (p.246):

"It is difficult to reach a consensus on how to define risk. Indeed different investors will have different concerns, depending on the nature of their portfolio and/or the nature of the institution that employs them. They will therefore perceive risk differently. A pension fund may see risk as the failure to face his liabilities. An asset manager may perceive risk as a deviation from its benchmark. A statistician may define risk as potential deviations from the average. And a private investor may consider the probability of missing a target return and by how much.[6]"

Hedge funds during the Asian crisis
The heart of de Brouwer's book concerns the role of hedge funds in the Asian financial crisis of 1997 and the subsequent controversy concerning a subject which has become a sensitive issue in relations between the world's traditional financial powers and several countries in the region. After allegations that hedge funds had contributed to the crisis an IMF study of spring 1998 downplayed their role[7]. The grounds for this conclusion were the small weight of hedge funds compared with other institutional investors in global financial markets, estimates - admittedly uncertain - of the scale of hedge funds' participation in the market for the Thai currency, the baht, and comparisons of the funds' leverage (and thus their capacity to take large positions in the markets for currencies and other assets) with that of the proprietary trading desks of other financial firms. Research by United States economists at the same time, which used data on hedge funds' returns from different asset classes and on their net assets values to make inferences about their positions, tended to support the first of the points of the IMF study. The work from these sources benefitted from being first in time and thus exerting a disproportionate influence on the subsequent debate, for example, serving as the source of Lhabitant's skimpy treatment of the subject. However, governments in the region continued to be concerned by the destabilising influence of hedge funds and other speculators in their financial markets, that of Hong Kong buying stock in its own market in August 1998 to thwart the so-called "double play[8]" and that of Malaysia imposing capital controls to restrict offshore operations in its currency, the ringgit.

The next major report from an international source, that of Working Group of the Financial Stability Forum (FSF) on Highly Leveraged Institutions in April 2000, expressed a more nuanced view as to the role played by hedge funds and other HLIs[9]. Acknowledging the difficulty of assessing the separate influences of more general market pressures on vulnerable features of some Asian economies, on the one hand, and of the operations of HLIs, on the other, the report none the less drew attention to "the potential" of "large and concentrated HLI positions…to influence market dynamics". This cautious conclusion, reflecting in part the need for compromise within the Working Group, was based on the findings of a Study Group of which de Brouwer was a member and which are also the principal base for the more detailed examination in his book of market dynamics in selected Asian economies around the time of the Asian crisis and its aftermath.

De Brouwer believes that the operations of macro hedge funds and to a lesser extent financial institutions' proprietary trading desks, though only one of many factors in the events of this crisis, were at times an important source of instability in the region's financial markets in 1997-1998 and contributed to the overshooting of exchange rates and other asset prices,. He is critical of the focus in the IMF study on the relative global size of hedge funds and other types of financial firm. What matters in his view is the size of their positions in relation to those of other actors in particular markets in the region. He also believes that too little attention has been paid to leader-follower patterns of behaviour in these markets: groups of hedge funds sometimes appear to act as if in packs and, vis-à-vis other firms, assume the role of leaders owing to their willingness to take large positions in particular assets and currencies based on what is widely regarded as superior knowledge. To exemplify his points de Brouwer reviews developments during this period in the markets of Thailand, Hong Kong, Indonesia, Malaysia, Singapore, Australia and New Zealand.

Concerning the Thai case de Brouwer gives estimates of the scale and timing of HLIs' short positions in the baht which differ from those of the IMF (larger and taken over a more extended period). In Hong Kong hedge funds assumed exceptionally large short positions in a wide range of assets, four large funds, for example, accounting for most of the doubling of short open positions in HSI (stock) futures in May and June 1998. Elsewhere hard data on market dynamics during 1997-1998 are less available and de Brouwer has relied heavily on his consultations with national authorities and market participants. He focusses primarily on exchange rates, and his findings as to the role of HLIs in cases of overshooting vary: for example, their influence was swamped by that of domestic residents in Indonesia in 1997 but was important in the depreciation of the Australian dollar in the early summer of 1998 (their large positions here being partly due to the depth and liquidity of the market for the Australian currency which faclitated its use for proxy hedges and other transactions with no connection to the economy's fundamentals).

De Brouwer also criticises the research on hedge funds mentioned above which attempts to infer their positions in different asset classes from data on the funds' aggregate returns and net asset values, whch, unlike their market positions, are publicly available information. The basic assumption here is that since the aggregate return of a fund is a weighted sum of the returns on its constituent assets, positions in these assets can be inferred through the multiplication of its net asset value by the coefficients estimated from a regression of the aggregate return on the returns of assets thought to be in its portfolio and thus serving as asset weights. De Brouwer has a number of technical objections to this approach, not least the arbitrary choice of indicators for returns on the assets assumed to be in the portfolio. Perhaps more importantly he tests the accuracy of the method by applying it to an artificial portfolio consisting of United States equities, yen, ringgit, Australian dollars, Singapore dollars, and the Indonesian rupiah. On the basis of historical data the aggregate monthly return on this portfolio is regressed on those of the six assets to estimate coefficients to be used as just described to calculate asset positions, which are then compared with actual positions. De Brouwer's finding is that the inferred positions differ substantially from the actual ones, often proving misleading with respect to magnitude, sign, and the timing of significant changes.

Regulation
As befits his practitioner focus, Lhabitant's discussion of regulation concerns rules bearing directly on firm structure, relations with investors, and transactions. For the United States he provides lucid and succint accounts of the key major laws dating from the period of the New Deal and of the 1996 National Securities Markets Improvement Act, all of which involve the oversight of the SEC, and of the rules which are the responsibility of the Commodity Futures Trading Commission and are relevant to hedge funds owing to their involvement in trading derivatives on organised exchanges. He notes that hedge funds are usually structured to take full advantage of various features of the United States regulatory and fiscal regimes (including gaps concerning subjects such as disclosure requirements). The book also includes briefer accounts of regimes in Switzerland, Germany, Italy, France, Ireland, and other offshore centres. However, the cut-off date for these accounts is not specified, and they do not include recent regulatory changes in several European countries sanctioning the sale of funds of hedge funds to retail investors.

De Brouwer's review of regulation is designed primarily to highlight areas where the crises of 1997-1998 indicated weaknesses of existing rules. Since many of these weaknesses involved cross-border operations, he believes that the approach to strengthening these rules should be international but, as a former official of the Reserve Bank of Australia with experience of the process of international policy making, is well aware of the problems of achieving international agreement on changes. His proposals are directed at various obectives: to reduce the potential of HLIs to be a source of systemic financial risk or otherwise destabilise financial markets; to ensure that all economic actors in financial markets are subject to supervision and market discipline which are adequate; and to ensure that decision makers – both supervisory authorities and market participants – have the necessary information for these purposes. In practical terms these objectives overlap, as is evident from de Brouwer's review of several initiatives and proposals since 1997-1998. De Brouwer examines at length the issue of greater disclosure concerning hedge funds' positions. This subject has proved more contentious than one might have expected. In December 1998 the Committee on the Global Financial System[10] set up a Working Group on Aggregate Positions (the Patat Group) to examine the scope for collecting and disseminating aggregate data on financial markets, but according to de Brouwer the initiative was eventually dropped largely under pressure from the Federal Reserve. This might be considered surprising in view of the existence in the United States of its own system for the reporting of foreign-exchange and derivatives positions and of the key role attributed to transparency in the functioning of its financial system[11]. Other topics considered by de Brouwer include the tightening of margin requirements on hedge funds (a subject of much attention after the LTCM crisis), a code of conduct for participants in the foreign-exchange markets, the regulation of electronic broking in these markets, and selective controls over capital transactions. Many of his reflections here bear not only on policy towards hedge funds but also on the broader issue of practical steps for improving international financial stability more generally.
