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

Considered an important signifier for a bullish breakout, a golden cross is a technical chart pattern that's formed when a stock's short-term moving average breaks above a longer-term moving average; the most common crossover involves the 50-day and the 200-day, 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.

Over the past four weeks, SPTN has gained 7.4%. The company currently sits at a #2 (Buy) on the Zacks Rank, also indicating that the stock could be poised for a breakout.

The bullish case solidifies once investors consider SPTN's positive earnings outlook. For the current quarter, no earnings estimate has been cut compared to 1 revisions higher in the past 60 days. The Zacks Consensus Estimate has increased too.

With a winning combination of earnings estimate revisions and hitting a key technical level, investors should keep their eye on SPTN for more gains in the near future.
