Understanding active share
Active management is a style that fundamentally rejects benchmark hugging and closet indexing. One key criteria of truly active management is active share: the percentage of stocks in a portfolio that are different from those in the benchmark.
When it comes to active share a higher number means more of the portfolio stand out from its index.
It tells us just how active a manager really is; rather than mirroring the benchmark, it measures how far the manager goes beyond it. The fees that you pay for active management should get you exactly that: high active share can help deliver benchmark-beating performance.
Many Dynamic equity fund overviews include the fund’s active share percentage to show how the portfolio manager is actively exploiting opportunities beyond the index.
High conviction portfolio management
Historically speaking, investment portfolios that have high industry concentrations typically outperformed their less concentrated benchmarks and peers.
The simplest way to measure a portfolio’s concentration is by the number of holdings it has. The lower the number of holdings, the higher the concentration. Portfolios with low concentration, in other words, a high number of holdings, are more likely to display muted portfolio performance.
Portfolio concentration by the numbers
Research shows that concentrated U.S. larger-cap equity portfolios outperformed their less concentrated counterparts by 115 bps, U.S. small-cap by 96 bps and EAFE 166 bps annually, after fees.
