An industry suffers, and regulators have not helped
HEDGE funds are supposed to hedge. This year, they haven’t. The fund-weighted composite index compiled by Hedge Fund Research, a firm that tracks the industry, fell by 4.7% in September, the second-worst month on record. Since the start of the year it has lost 9.4%. The industry’s promises of “absolute returns” for investors now ring rather hollow.
To be fair to them, hedge funds have not been allowed to hedge. The restrictions on short-selling (betting on falling prices) imposed by regulators round the globe have played havoc with managers’ strategies in recent weeks.
Take the worst-performing strategy, convertible arbitrage, which lost the average fund 12% in the month. Convertible bonds are fixed-income securities that can be exchanged for shares in the issuing company. Historically, these bonds have been underpriced, because too low a value has been placed on the right to convert them to equity. So arbitrage managers have tended to buy the bonds and sell short the shares. Thanks to the Securities and Exchange Commission’s ban on the shorting of more than 900 stocks from September 19th to October 8th, that strategy no longer worked. And since the managers could not short the shares, they had to sell the bonds. As a result, the bonds’ prices plunged.
Perversely, issuing convertible bonds would have been one way for banks to raise capital. But that route has been cut off, a typical example of the unintended consequences of meddling with the markets in response to populist pressures.
Another strategy that has suffered is statistical arbitrage, known in the trade as “stat arb”. Such funds use computer models to look for anomalies in the market, and exploit these wrinkles by buying and selling shares very rapidly. By doing so, they provide liquidity to the system, in effect acting as marketmakers.
Without the ability to short many shares, stat-arb models have been disrupted. The cost of trading in such stocks (defined by the difference between the bid and offer prices) duly rose, more than doubling according to Credit Suisse. The market became less liquid, adding to the volatility of share prices in recent weeks.
And then there is the most popular type of hedge fund, long-short equity. Such funds rely on the stockpicking ability of their managers, buying their favourite shares and shorting companies they dislike. If the managers make the right selections, they can protect investors from a falling stockmarket. In the first half of the year, for example, a popular strategy was to buy commodity-related stocks (such as miners) and short the banks.
Again, the shorting ban disrupted that strategy, forcing managers to cut their long positions as well as their shorts. Because many in the market were well aware of the favourite positions of hedge-fund managers, prices of some of those shares have fallen rapidly–another unintended consequence of the shorting ban.
Nor is that the end of the hedge funds’ problems. As an investment bank, Lehman Brothers was active in prime brokerage, a vital source of finance for hedge funds. When prime brokers lend money to hedge funds, the funds are required to put up collateral (Treasury bonds and the like). Lehman then used this collateral as security for its loans, a standard industry procedure known as “rehypothecation”. But the result has been that assets belonging to some hedge funds have been ensnared by Lehman’s bankruptcy. One leading lawyer describes this as “an unmitigated disaster”.
In addition, the remaining prime brokers have become more cautious about their exposure to hedge funds. This week the IMF cited figures showing that funds are now required to put up collateral of 25-40% of the capital when trading in high-yield bonds, against 10-15% in April 2007.
All this means that hedge funds have been unable to ride to the rescue of global markets. According to the IMF, the average cash balance of hedge funds has risen from 14% last year to 22%, while the amount of leverage (borrowed money) they use has fallen from 70% of capital to 40%. In theory, that gives them the firepower to buy now that prices have fallen; in practice, they may need their cash to repay clients that want to redeem their holdings. Charles MacKinnon of Thurleigh, a fund manager for private clients, says it has given notice on some 70% of its hedge-fund positions.
Individual hedge funds will doubtless be brought down by this crisis. Their fall will have far less economic impact than that of either Lehman or Bear Stearns, although if they are forced to sell assets that will not help the banks. But the industry can feel justifiably aggrieved. It has not only been clobbered by a crisis that started in a regulated industry (investment banking), but it has been given a good kicking by the regulators too.更多精彩文章及讨论,请光临枫下论坛 rolia.net
