Exchange traded funds that invest in some of the market’s riskier sectors have seen the sharpest rallies in the bounce in stocks over the past week.

The Federal Reserve statement released Wednesday afternoon didn’t contain any real surprises on interest rates and the economy, and markets were generally muted after the decision.
