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

A golden cross is a technical chart pattern that can signify a potential bullish breakout. It's formed from a crossover involving a security's short-term moving average breaking above a longer-term moving average, with the most common moving averages being 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 contrasts with a death cross, another widely-followed chart pattern that suggests bearish momentum could be on the horizon.

Shares of ETR have been moving higher over the past four weeks, up 12%. Plus, the company is currently a #3 (Hold) on the Zacks Rank, suggesting that ETR could be poised for a breakout.

The bullish case only gets stronger once investors take into account ETR's positive earnings outlook for the current quarter. There have been 2 upwards revisions compared to none lower over the past 60 days, and the Zacks Consensus Estimate has moved up as well.

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