What Is Moving Average Crossover?
Moving average crossover is the simplest trend-following system: buy when a shorter-period MA crosses above a longer-period MA (golden cross), sell when it crosses below (death cross). Common pairs: 50/200 SMA for long-term, 9/21 EMA for short-term, 12/26 for medium.
The strategy captures sustained trends well but underperforms in choppy markets, where crossovers happen repeatedly without follow-through, generating losses on each whipsaw. Backtest data consistently shows MA crossover strategies struggle in sideways years (e.g. 2015, 2018) and shine in trending years.
The golden cross (50/200 SMA cross upward) and death cross (downward) are widely-watched market signals in financial media, though their actual predictive value at the index level is modest. On individual stocks with strong trending behavior, crossovers can be useful entries — combined with a regime filter like ADX > 25.
