Only about 9.3% of the 30 million defined contribution participants in the Investment Company Institute's Plan Participants' Activities study changed their allocations in 2017. In the 10-year period covered by the study, the high occurred in historically volatile 2008, when 14.4% made changes. In 2013, 10.7% made changes, and the percentage has been dropping since.
The continuing trend toward passive management and target-date funds likely played into the decline; they offer a hands-free approach to asset allocation and eliminate the fatigue, expense and volatility of chasing active returns or timing markets.
