Russell 2000 ETF (IWM) lagged the larger S&P 500 ETF (SPY) by nearly 9 percentage points since the end of the third quarter of 2018 as investors worried over the possible ramifications of rising interest rates and escalation of the trade war with China. The hedge funds and institutional investors we track typically invest more in smaller-cap stocks than an average investor (i.e. only 298 S&P 500 constituents were among the 500 most popular stocks among hedge funds), and we have seen data that shows those funds paring back their overall exposure.
