From a technical perspective, Pure Storage (PSTG Quick QuotePSTG - Free Report) is looking like an interesting pick, as it just reached a key level of support. PSTG recently overtook the 20-day moving average, and this suggests a short-term bullish trend.

A well-liked tool among traders, the 20-day simple moving average offers a look back at a stock's price over a 20-day period. This is very beneficial to short-term traders, as it smooths out short-term price trends and gives more trend reversal signals than longer-term moving averages.

Like other SMAs, if a stock's price is moving above the 20-day, the trend is considered positive. When the price falls below the moving average, it can signal a downward trend.
