Twilio Inc. (TWLO Quick QuoteTWLO - Free Report) is looking like an interesting pick from a technical perspective, as the company reached a key level of support. Recently, TWLO'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 is the opposite of a death cross, another technical event that indicates bearish price movement may be on the horizon.

TWLO has rallied 16.7% over the past four weeks, and the company is a #3 (Hold) on the Zacks Rank at the moment. This combination indicates TWLO could be poised for a breakout.

Looking at TWLO's earnings expectations, investors will be even more convinced of the bullish uptrend. For the current quarter, there have been 8 changes higher 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 TWLO for more gains in the near future.
