SJW Group (SJW Quick QuoteSJW - Free Report) reached a significant support level, and could be a good pick for investors from a technical perspective. Recently, SJW's 50-day simple moving average broke out above its 200-day moving average; this is 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.

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.
