A "golden cross" is a technical analysis pattern that occurs in financial markets, particularly in stock trading. It happens when a short-term moving average, like the 50-day moving average, crosses above a long-term moving average, such as the 200-day moving average. This crossover is often seen as a bullish signal, indicating potential upward momentum in the asset's price. Traders and investors watch for a golden cross as it may suggest a shift in market sentiment. It can be a sign to buy, as it implies that the asset could continue to rise in value. However, like all indicators, it should be used in conjunction with other analysis tools.
