From a technical perspective, Teradyne, Inc. (TER Quick QuoteTER - Free Report) is looking like an interesting pick, as it just reached a key level of support. TER'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.

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

TER could be on the verge of a breakout after moving 30.3% higher over the last four weeks. Plus, the company is currently a #2 (Buy) on the Zacks Rank.

Looking at TER's earnings expectations, investors will be even more convinced of the bullish uptrend. For the current quarter, there have been 7 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 TER for more gains in the near future.
