From a technical perspective, Astria Therapeutics, Inc. (ATXS Quick QuoteATXS - Free Report) is looking like an interesting pick, as it just reached a key level of support. ATXS's 50-day simple moving average crossed above its 200-day simple moving average, which is known as a "golden cross" in the trading world.

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.

This kind of chart pattern is the opposite of a death cross, which is a technical event that suggests future bearish price movement.

ATXS has rallied 19.8% over the past four weeks, and the company is a #3 (Hold) on the Zacks Rank at the moment. This combination indicates ATXS could be poised for a breakout.

The bullish case solidifies once investors consider ATXS's positive earnings outlook. For the current quarter, no earnings estimate has been cut compared to 5 revisions higher in the past 60 days. The Zacks Consensus Estimate has increased too.

Investors should think about putting ATXSon their watchlist given the ultra-important technical indicator and positive move in earnings estimates.
