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, suggesting that the stock's long-term trend may be changing. In the case of Bank Bradesco, the formation of a golden cross could lead to an increase in its 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.
