Hedge fund managers are the new "masters of the universe." The best earn more than $1 billion a year and are so sought after that they can afford to turn investor money away. The funds they run have, to some extent, established an alternative financial system, replacing banks as lenders to risky companies, acting as providers of liquidity to markets and insurers of last resort for risks such as hurricanes, and replacing pension funds and mutual funds as the most significant investors in many companies—even in some cases buying companies outright. The revised and updated second edition of this lively guide sheds much needed light on the world of hedge funds by explaining what they are, what they do, who the main players are, the regulations affecting them, the arguments as to whether they are a force for good or bad, and what the future holds for them.
