A hedge is an investment made solely to reduce the risk associated with another investment. The classic example of a hedge is a pairs trade. Let's say that you hear that GM is coming out with three new cars in 2007 and you are convinced that they are going to start making money. (Note: this is hypothetical.) You might feel confident about GM but lack confidence in the auto sector. You may be concerned, for example, about the price of gas or the economy in general. Your confidence is that GM will outperform the rest of the auto sector. What do you do? The easy answer is that you buy GM and you short Ford. You have "hedged" your GM investment.
Hedge Funds are created to use hedging techniques to make money. They are not about risk mitigation. Hedge funds are all about greed. They are geared to achieve a greater return than mutual funds but they do so by taking larger risks than mutuals. This risky activity is attractive at the present time because equities have been flat since 1999 and savings interest rates are modest.
Two-thirds of all hedge funds assets are registered offshore. This even despite the fact that hedge funds are lightly regulated. Hedge funds are not required to register with the SEC.
In general, hedge funds are places where fairly wealthy folks park their money to make some more. Hedge funds, generally speaking, do not own real assets but rather derivative assets. Many of them do what the example cited above suggests. They go long in one stock and short in another. They also may make incredibly complicated derivative trades based of computerized modeling.
Hedge funds tend to be organized as partnerships and steer well clear of SEC regulation. The SEC had ruled that not hedge funds but most hedge funds advisers had to register with them but that rule was recently tossed by a US Appeals Court.
The most notorious example of a hedge funds gone bad is LTCM. LTCM (Long Term Capital Management) had a diversified portfolio and an incredibly sophisticated model. It made one simple mistake. It assumed that markets would behave in the future as they had in the past. Perhaps more accurately it failed to associate a probability with a particular unlikely event. The failure of LTCM was due to various factors but unquestionably it was the fact that In August 1998 Russia defaulted on its bonds. That was an eventuality that the model never foresaw. Four days after the Russian default LTCM lost $500 million in one day.
It's Worse Than That
LTCM was highly leveraged. The amount of money that it had "in play" was vastly larger than its assets. In short, it was losing borrowed money. It had $4.72 billion of equity but leveraged that to $125 billion. Fixed income securities markets (among others) offer much more leverage than equities markets do.
Derivative investments are zero-sum things like poker games. The fact that some fat cats lost money meant that some other fat cats made money. No problem. But when the fat cats lose BORROWED money they are creating systemic risks in both the banking and brokerage industries. LTCM had counterparties: banks and broker/dealers who could have lost vast sums concomitant to LTCM's losses. It LTCM could not meet its obligations then its banking partners, the broker/dealers who executed the transcations for LTCM and the banks of those broker/dealers would suffer the losses.
The Federal Reserve Bank of New York rapidly recognized that the LTCM debacle threatened banks and security brokers and arranged a $3.5 billion infusion of cash to LTCM in exchange for a gigantic dilution of LTCM ownership. Note that the Fed did not bail out LTCM with public money. It helped to arrange financing for the LTCM dilution. LTCM had lost $4.6 billion in 4 months. This company which collapsed in 1998 had on its board of directors 2 guys who won the Nobel Prize in Economics in 1997. The Fed was not bailing out LTCM it was protecting the banks and the broker/dealers. That is of substantial concern to the Fed.
What is This All About?
Good question. I don't see LTCM as anything resembling the Solomon Brothers disasters on the 1980's. Those involved, among other things, phony bids on US Treasuries. LTCM was about a computer model that folks became too enamored with. It was one of those situations where the model was correct 99.9% of the time but that 1 in a thousand thing happened and, essentially, wiped them out.
So What Are the Risks?
The risks generated by hedge funds may in fact be too complex to understand. There may be situations where hedge funds increase market volatility and exacerbate losses. The real dangers created by hedge funds are to the counterparties. The counterparties are the banks that provide financing for their leveraging and the broker/dealers who clear their transactions.
I believe that these risks were well addressed by Bernanke in his speech in Atlanta on May 16, 2006. As an aside it is worth reading this relatively short paper because, unlike his predecessor, Bernanke speaks in comprehensible English.
Bernanke address the issue of regulation of hedge funds by implying that regulation of hedge funds is not practical but risk mitigation is best achieved by getting the counterparties which provide the leverage to hedge funds (banks and securities broker/dealers) to better understand what their customers are doing and to minimize the risks.
Part of the problem is that for a hedge fund to function it must not reveal its entire portfolio or strategy outside its circle of investors. To some extent this is a high stakes poker game and the casino can't ask the players to show their cards.
Another issue with hedge funds is that some of the things which they trade - credit derivatives for example. - are relatively new and we do not have a good collective understanding of what can happen with these. A credit derivative is a type of derivative security whose value at maturity is dependent on some credit event. Private Mortgage Insurance once common to the mortgage industry would be an example.
In essence credit derivatives are vehicles whereby banks can pass the credit risk to someone else at a cost.
There are arguments to be made on both sides as to whether or not credit derivatives are healthy for the economy or potential sources of massive disaster. Warren Buffet referred to credit derivative as "weapons of mass destruction." This was after a company he purchased - Gen Re - suffered substantial losses in credit derivatives. Greenspan said regarding credit derivatives "that benefits have materially exceeded the costs.”
For me the answer is that these derivatives and other hedges have a purpose which well serves the folks who should be using them but that there may well be a large number of relatively ill-informed, greedy folks who misuse these and have the potential of creating disasters which spread beyond merely their own funds but also to the banking system and the security dealers who clear these transactions.
More Potential Trouble
The potential for viral problems to spread from hedge funds collapses is simply unknown but hardly trivial. The problem is that, being highly leveraged, a collapsing hedge fund could create second order market shocks. Hedge funds could be forced to liquidate positions creating fire-sale scenarios. While there are certainly massive opportunities to make a profit by those who are liquid and can buy those assets at low prices there may well be other individuals and funds who because they are moderately leveraged are forced to sell their positions because they have their margins called.
As in 1998 with the default of Russian debt the trigger for such an event could come from many places.
In a nutshell, a hedge fund says: "If you model the economy correctly there is always a play where you can make a buck. It matters little how the market actually moves." Left unsaid is that if you model it incorrectly you can lose your butt with remarkable speed.
The Real Problem
The real problem may be no more than an intellectual one. It is simply hindsight bias. We can construct models which perfectly describe the past and feel confident that they are very likely to describe the future. The true difficulty is ascribing probabilities to events which we might anticipate as being probable but unlikely. There is a scholarly piece on this by Eliezer Yudkowsky. The problem is that it is often difficult or impossible to ascribe a correct probability to a low probability event. In short, if the long-term success of a model depends on one ability to correctly estimate whether the probability of a nation defaulting on its debt in a give year is is 1/1000 or 1/100,000 the process may be intellectually futile.
It is a facet of human nature that we are inclined to be overconfident in estimating that which we do not really know. That little sentence may be the heart of the matter.
Ascribing probabilities to casino games is simple because these involve the activities of sterilized systems. The dice are manufactured with an exactness to assure the predictability to the randomness. Ascribing a probability to an event such as an 8.5 earthquake in a major California city or a category 5 hurricane hitting Miami at least has some data to go on. Ascribing a probability to an outliner event such as 9/11, the Russian debt default or a large comet striking the earth is a more daunting task.
Hedges are important economic tools to mitigate the risk to valid investments. Hedge funds are about nothing other than greed. Their main economic purpose and the reason they are tolerated is that they provide profitable business to the broker/dealer community and also additional participation to the trading of derivative thus mitigation the volatility of those. Volatility is always diminished by additional market participation. Unfortunately the price of that day-to-day mitigation of volatility may be a disaster every couple of decades. It is not hard to imagine that for the sake of keeping what may be one of its best customers a broker/dealer would give less than a thorough inspection of the practices of a hedge fund.
In brief, calculating the correct probability that a hedge fund triggered event causes massive harm to the US economy is, unfortunately, impossible.
