From a technical perspective, CubeSmart (CUBE Quick QuoteCUBE - Free Report) is looking like an interesting pick, as it just reached a key level of support. CUBE's 50-day simple moving average crossed above its 200-day simple moving average, which is known as a "golden cross" in the trading world.

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.

There are three stages to a golden cross. First, there must be a downtrend in a stock's price that eventually bottoms out. Then, the stock's shorter moving average crosses over its longer moving average, triggering a positive trend reversal. The third stage is when a stock continues the upward momentum to higher prices.

This kind of chart pattern is the opposite of a death cross, which is a technical event that suggests future bearish price movement.

Shares of CUBE have been moving higher over the past four weeks, up 19.7%. Plus, the company is currently a #3 (Hold) on the Zacks Rank, suggesting that CUBE could be poised for a breakout.

Once investors consider CUBE'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 2 revisions higher, and the Zacks Consensus Estimate has increased as well.

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