After reaching an important support level, Pure Storage, Inc. (PSTG Quick QuotePSTG - Free Report) could be a good stock pick from a technical perspective. PSTG recently experienced a "golden cross" event, which saw its 50-day simple moving average breaking out above its 200-day simple moving average.

There's a reason traders love a golden cross -- it's a technical chart pattern that can indicate a bullish breakout is on the horizon. This kind of crossover is formed when a stock's short-term moving average breaks above a longer-term moving average. Typically, a golden cross involves the 50-day and the 200-day moving averages, since bigger time periods tend to form stronger breakouts.

A successful golden cross event has three stages. It first begins when a stock's price on the decline bottoms out. Then, its shorter moving average crosses above its longer moving average, triggering a positive trend reversal. The third and final phase occurs when the stock maintains its upward momentum.

A golden cross is the opposite of a death cross, another technical event that indicates bearish price movement may be on the horizon.

PSTG has rallied 34% over the past four weeks, and the company is a #3 (Hold) on the Zacks Rank at the moment. This combination indicates PSTG could be poised for a breakout.

Looking at PSTG's earnings expectations, investors will be even more convinced of the bullish uptrend. For the current quarter, there have been 10 changes higher compared to none lower over the past 60 days, and the Zacks Consensus Estimate has moved up as well.

Given this move in earnings estimates and the positive technical factor, investors may want to keep their eye on PSTG for more gains in the near future.
