These articles are very misleading. They are implying that these funds did poorly simply because stocks sold off. The fact of the matter is many of these funds are highly concentrated in emerging markets, in debt, currency and equity. They went there chasing yield because bond yields in the US are shit and dividend yields in the S&P are shit. This is what hedge funds get paid to do. Could some of them been better hedged? Perhaps. The problem is, hedging emerging market risk many times is simply adding additional risk. It's not as straightforward s hedging US exposure.
