Vulcan Materials Company (VMC Quick QuoteVMC - Free Report) reached a significant support level, and could be a good pick for investors from a technical perspective. Recently, VMC'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.

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 contrasts with a death cross, another widely-followed chart pattern that suggests bearish momentum could be on the horizon.

VMC has rallied 14.1% over the past four weeks, and the company is a #1 (Strong Buy) on the Zacks Rank at the moment. This combination indicates VMC could be poised for a breakout.

Once investors consider VMC'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 7 revisions higher, and the Zacks Consensus Estimate has increased as well.

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