Arcturus Therapeutics Holdings Inc. (ARCT Quick QuoteARCT - Free Report) is looking like an interesting pick from a technical perspective, as the company reached a key level of support. Recently, ARCT'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.

Golden crosses have three key stages that investors look out for. It starts with a downtrend in a stock's price that eventually bottoms out, followed by the stock's shorter moving average crossing over its longer moving average and triggering a trend reversal. The final stage is when a stock continues the upward climb 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.

Shares of ARCT have been moving higher over the past four weeks, up 38.3%. Plus, the company is currently a #3 (Hold) on the Zacks Rank, suggesting that ARCT could be poised for a breakout.
