摘要：我们发现，当投资组合集中在每一个行业的前一个或两个股票时，积极管理的股票型共同基金的业绩会增加🙍🏽‍♀️。由一个基金经理管理的基金有更集中的投资组合，其表现往往更好，并且比由多个经理管理的基金有更高的费用比率。我们还发现，当一个基金的管理设计从单一管理者转变为多个管理者时👨，投资组合内部以及跨部门的集中度📻、绩效和费用比率会降低。

ABSTRACT

We show that the performance of actively managed equity mutual funds increases when portfolios are concentrated in the top one or two stocks within each industry sector. Funds managed by a single manager have much more concentrated portfolios, tend to perform better, and have higher expense ratios than funds managed by multiple managers. We observe that when a fund’s management design is changed from single manager to multiple managers, the portfolio’s within- and cross-sector concentration, performance, and expense ratios decrease.
