We examine how mutual fund flows that are correlated with subsequent fund returns can have a dilution impact on the performance of open-end funds. Active trading of open-end funds has a meaningful economic impact on the returns of passive, nontrading shareholders, particularly in U.S.-based international funds. The overall sample of domestic equity funds shows no dilution impact, but we find an annualized negative impact of 0.48% in international funds (and nearly 1% for a subsample of funds whose daily flows are particularly large). The exchange and pricing policies of mutual funds can thus have important performance-related implications.

We examine the impact deciding to route limit orders away from the New York Stock Exchange (NYSE) has on three dimensions of execution quality with methodologies controlling for market conditions and order submission strategies. Overall differences in limit order execution quality between regional stock exchanges and the NYSE are small, suggesting that the order routing decision may not affect retail limit order traders substantively. Conditioning on the distance between the limit order's price and prevailing quotes, however, reveals systematic differences in execution quality. This implies that brokers can strategically route limit orders to improve retail limit order execution quality.
