Well, I think you monitor lot of small or micro caps. As you may know, these stocks began to underperform long time before large caps. These last days, it happened the contrary : small caps outperformed. So this is normal some small caps with heavy short sellers show abnormal returns. But don't be naive : majority of these stocks will again underperform. Maybe you can find some gems, but be careful. For 1 gem, 9 big losers. Good trades. CM
