Gamida Cell Ltd. is looking like an interesting pick from a technical perspective, as the company reached a key level of support. Recently, GMDA's 50-day simple moving average crossed above its 200-day simple moving average, known as a "golden cross."

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 contrasts with a death cross, another widely-followed chart pattern that suggests bearish momentum could be on the horizon.

GMDA could be on the verge of a breakout after moving 8.4% higher over the last four weeks. Plus, the company is currently a #3 (Hold) on the Zacks Rank.

Once investors consider GMDA's positive earnings outlook for the current quarter, the bullish case only solidifies. No earnings estimate has gone lower in the past two months compared to 3 revisions higher, and the Zacks Consensus Estimate has increased as well.

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