Read27 asset allocation to alternative investment中有这么一句话，烦请网友能帮忙解释下什么含义：Most hedge fund arbitrage strategies involve some degree of "short volatility" risk. Because of the "short volatility” risk , the volatility in an arbitrage strategy is non-symmetrical;the aggregate volatility may look muted if the period from which the data are drawn does not inclued amarket stress period.
