What if the fund makes 25% year after year for 5 years, loses 20% year after year for 5 years, and then all the investors pull their money out?
I chose alternating 25/-20% returns because they make the math simple. Very few markets actually behave like this: instead, you're likely to get 5-10 years of excellent performance, followed by 3-5 years of incredibly depressing performance. The numbers become harder to figure with this, but qualitatively, the conclusion remains the same.
In practice, hedge funds often do well while whatever they invest in is rising, and then "blow up" entirely when they start to underperform and investors run for the exits. Think LTCM or Amaranth, and it happens regularly on a smaller scale. The managers make hefty fees in the good times, and the investors are left holding the bag when the fund blows up.
Lots of hedge funds (the good ones at least) get out of this by requiring minimum investment periods. This prevents a focus of the LP's on short term gains/losses, but also prevents the run for the door.
