A crossover involving a security's short-term moving average (such as 15-day moving average) breaking above its long-term moving average (such as 50-day moving average) or resistance level.

As long-term indicators carry more weight, the Golden Cross indicates a bull market on the horizon and is reinforced by high trading volumes. Additionally, the long-term moving average becomes the new support level in the rising market.

Technicians might see this cross as a sign that the market has turned in favor of the stock.
