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