Investor–Stock Decoupling in Mutual Funds
研究了共同基金中投资者与股票持有地分离的现象，发现这种分离能带来自然对冲，减少市场波动时的资金流动，并提升基金业绩，尤其在金融危机期间更明显。
We investigate whether mutual funds whose investors and stocks are decoupled (i.e., investor location does not coincide with that of the stock holdings) benefit from a natural hedge as they have fewer outflows during market downturns and fewer inflows during upturns. Using a sample of equity mutual funds from 26 countries, we find that funds with higher investor–stock decoupling exhibit higher performance, and this is more pronounced during the 2007–2008 financial crisis. We also find that decoupling allows fund managers to take less risk, be more active, and tilt their portfolios toward smaller and less liquid stocks.
