Commvault Systems (CVLT Quick QuoteCVLT - Free Report) is looking like an interesting pick from a technical perspective, as the company reached a key level of support. Recently, CVLT crossed above the 20-day moving average, suggesting a short-term bullish trend.

The 20-day simple moving average is a well-liked trading tool because it provides a look back at a stock's price over a 20-day period.
