Mean Reversion vs Trend Following: Which Is Better?

Compare mean reversion and trend following styles, learn when each works best, and how to combine them in a diversified trading approach.
Every trading strategy broadly falls into one of two camps: betting that prices will revert to the mean, or betting that prices will continue in the same direction. Knowing when each style works is essential for building a robust portfolio.
Mean Reversion
Mean reversion assumes extreme price moves are temporary and prices eventually return to an average. Tools include RSI, Bollinger Bands, and z-scores. This style thrives in sideways, range-bound markets.
Trend Following
Trend following assumes that prices that have been rising are more likely to keep rising, and vice versa. Tools include moving averages, MACD, and breakout systems. This style thrives in strong directional markets.
Combining Both
No single style works in every regime. Many professional traders run both mean-reversion and trend-following systems so that at least part of the portfolio performs well regardless of market conditions.
