Third Quarter 2016 Review

The third quarter saw ebbs and flows in trading activity for 401(k) investors. The quarter began with high trading activity driven by market volatility in the wake of the Brexit vote. August was one of the lightest trading months on record while September saw more of a return to normal activity.

Trades in the third quarter generally favored fixed income over equities with GIC/stable value, bond, and money market funds receiving the majority of the inflows and large U.S. equity funds, company stock, and small U.S. equity funds having the most outflows.
