Earnings season has been unkind to a number of recent leaders like Taser International (TASR), but it has spurred plenty of other stocks to breakouts or big gains. The market uptrend is still under pressure, but these stocks aren’t letting that get in their way. The IBD 50 index rose 0.4% for the week. Ellie Mae (ELLI), No. 2 in Wednesday’s issue, posted the biggest gain in the IBD 50 Friday after gapping up 13% to a new high.
