By comparison, the average fund in our Morningstar World Stock peer group holds 147 different equities, over four times the number of companies held in Mundoval.1While diversifying investments can have positive effects, mutual funds that are spread too thin run the risk of diluting the returns of their top stock selections. In fact, several studies have linked concentrated portfolios to greater performance over time:
- Emory University professors found that portfolio managers who ran concentrated portfolios outperformed more diversified funds by 4% each year.2
- Yale researchers developed a measurement called “Active Share” to determine the proportion of a mutual fund that did not overlap with its index. More concentrated funds generally held fewer stocks in common with their index and scored a higher active share as a result. The study further found that concentrated, high-active share funds consistently outperformed more diversified funds and their benchmarks, even after fees.3
