Sector leaders are the stocks that outperform their own sector, the names fund managers rotate into when money flows to the group. The Industrial Select Sector SPDR ETF (XLI) tracks the large industrial companies of the S&P 500, so beating XLI means beating the sector itself. This list shows NYSE and Nasdaq industrial stocks whose price gain over the last month (21 trading days) is greater than that of XLI, the top 100 by one-month gain, with the lead over XLI in percentage points. Penny stocks and illiquid names are excluded.
