Below we highlight the average short interest as a percentage of float for stocks in each S&P 500 sector. As shown, Consumer Discretionary stocks in the S&P 500 are the most heavily shorted, with an average of 5.74% of shares sold short. Materials, Technology, and Financials are the three other sectors with short interest numbers higher than the S&P 500 as a whole. Unsurprisingly, given their high yields and low volatilities, Utilities stocks are the least shorted in the S&P 500. But it is somewhat surprising to see the Industrial sector as the second least shorted sector in the S&P 500.
