Increased allocation to equity long-short strategy during extreme volatile markets is precisely the worst thing to do. Thats where some hedge-funds have made mistake.
Much of the problem this year has come from extreme price movements in different markets. The S&P 500 has moved by 1 percent or more on about half of all trading days this year, according S&P. The last time the percentage hovered at that level was in 1938. Commodities prices have also moved wildly. This year, crude oil has fallen below $90 a barrel twice and jumped to a high of $110 a barrel. U.S. dollar has lost 4.13 percent this year against a trade-weighted basket of currencies tracked !!!
No hedge is perfect. In periods of unusual volatility, hedges are more likely to fail. They are much more likely to outperform in a low-volatility bear market than in a high-volatility messy market. Much of their "black-box" complex algorithamic models start to behave abnormally during volatile markets as they are unable to forecast anything clearly & bad trades happens... I have heard - at times of extreme volatility, some Hedge Funds does wise thing - put algors to rest :)
If Hedge Funds are investing in a relative-value play, then volatility works against them. It's only the noise traders who really make money from volatility, and they're actually a minority in the hedge-fund world. Anyhow, if a Fund hasen't blown up yet, money will keep pouring !!
