Golden cross patterns occur in three stages: stage one occurs at the end of a security's downturn, signaling the completion of a sell cycle. Stage two is the crossover of the short- and long-term moving averages, followed by a trading breakout. The final stage sees the security continue its upwards trajectory, with accompanying price increases. Eventually, a pullback occurs, leading to a golden cross' inverse – the Death Cross.
Golden crosses can be composed of variable moving averages, from minutes- to months long. Longer time periods typically equate to more sustained breakouts. 50-day short term and 200-day long term periods are most common for their ability to remove daily volatility from the equation, painting a more accurate picture of a security's trajectory.
Day traders will use shorter windows of time, evaluating moving averages throughout a trading day to identify and trade golden crosses – 5-period and 15-period moving averages are common for their purposes. Traders use momentum indicators like moving average convergence divergence
(MACD) and relative strength index
(RSI) in conjunction with golden crosses to gauge ideal times to buy in or sell off security.
For all their popularity, no golden cross is 100 percent reliable – a golden cross in unstable market conditions will not always result in a bull market, especially for single equities. Research indicates short-term gains may emerge but can be less substantial – around 1.31 percent for the 30-day period post-golden cross. 12-month average gains, however, were found to be around 11 percent.
