Atour Lifestyle Holdings Limited Sponsored ADR (ATAT Quick QuoteATAT - Free Report) is looking like an interesting pick from a technical perspective, as the company reached a key level of support. Recently, ATAT's 50-day simple moving average crossed above its 200-day simple moving average, known as a "golden cross."

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.

There are three stages to a golden cross. First, there must be a downtrend in a stock's price that eventually bottoms out. Then, the stock's shorter moving average crosses over its longer moving average, triggering a positive trend reversal. The third stage is when a stock continues the upward momentum to higher prices.

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, ATAT has gained 8.5%. The company currently sits at a #3 (Hold) on the Zacks Rank, also indicating that the stock could be poised for a breakout.

The bullish case only gets stronger once investors take into account ATAT's positive earnings outlook for the current quarter. There have been 1 upwards revisions compared to none lower over the past 60 days, and the Zacks Consensus Estimate has moved up as well.

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