On Friday, the S & P 500 closed below its 200-day moving average for the first time since March 17.

Still, the fund's rule tied to the 200-day moving average is an example of how the move of a stock or index across a widely-followed indicator can cause volatility. Year to date, the fund is up just under 5% — well below the gain of more than 11% for the SPDR S & P 500 ETF Trust (SPY) .
