The golden cross is a technical indicator that occurs when a stock's 50-day moving average crosses above its 200-day moving average. This is generally considered a bullish signal, as it may indicate a change in the long-term trend. In the case of Constellation Brands, the formation of a golden cross could lead to an increase in the stock price in the short term. However, it is important to note that seasoned investors use the golden cross as a signal to start looking for long positions based on other factors, such as price levels and company fundamentals.
