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