"The S&P 500 Index has now outperformed its hedge-fund rival for ten straight years, with the exception of 2008 when both fell sharply. A simple-minded investment portfolio—60% of it in shares and the rest in sovereign bonds—has delivered returns of more than 90% over the past decade, compared with a meager 17% after fees for hedge funds (see chart). As a group, the supposed sorcerers of the financial world have returned less than inflation. Gallingly, the profits passed on to their investors are almost certainly lower than the fees creamed off by the managers themselves."
~ The Economist, from Hedge Funds: Going Nowhere Fast
Note: The expense ratio on a Vanguard S&P500 Index ETF is only 0.05%, which is 1/20th of 1 percent, or just $50 per $100,000 of investment funds, or basically almost free. So you can invest for almost free using index funds and ETFs, or pay hedge fund managers large fees to earn much lower returns.
