Resideo Technologies, Inc. (REZI Quick QuoteREZI - Free Report) is looking like an interesting pick from a technical perspective, as the company reached a key level of support. Recently, REZI'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.

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

Over the past four weeks, REZI has gained 26.5%. The company currently sits at a #1 (Strong Buy) on the Zacks Rank, also indicating that the stock could be poised for a breakout.

Once investors consider REZI'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 1 revisions higher, and the Zacks Consensus Estimate has increased as well.

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