After reaching an important support level, AMETEK, Inc. (AME) could be a good stock pick from a technical perspective. AME recently experienced a "golden cross" event, which saw its 50-day simple moving average breaking out above its 200-day simple moving average.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.AME could be on the verge of a breakout after moving 8.8% higher over the last four weeks.
