Momentum strategies involve buying assets that are rising in price and selling those that are falling, capitalising on the tendency of trends to persist. Mean reversion strategies do the opposite — betting that prices will return to their historical average after moving too far away.

These two approaches suit different market conditions. Momentum performs best in strong trending markets where prices continue in the same direction. Mean reversion works better in range-bound or oscillating markets where prices repeatedly return to a central level after reaching extremes.

Being early in either strategy feels intuitive but often leads to poor results. Entering a mean reversion trade too soon exposes the position to further price deviation, causing larger drawdowns before the expected reversal. Entering momentum trades too early can result in whipsaws or missed trend strength, tying up capital with little reward.

The cost of being early includes opportunity cost, psychological strain, and the risk of multiple stop-outs. Exhaustion Model, Crash Model, and Climax-Capitulation indicator assist in avoiding being early by confirming when prices are overextended to the downside, signaling potential mean reversion opportunities.

Regime awareness determines the right behaviour. Market Monitors define whether the market is in a trending phase (favouring momentum) or an exhaustion/range-bound phase (favouring mean reversion). The VIX Decomposition Risk State and Volatility Monitors further refine this by showing whether volatility supports continuation or reversal.

In practice, traders can reduce the cost of being early by waiting for confirmation, higher volume, multiple timeframe alignment, or technical breakouts. Momentum models like MoMo, MoPB, MoEat, and Price Thrust provide exactly that confirmation, ensuring entries only when the market is already starting to move in the desired direction.

Ultimately, market conditions dictate which behavior is rewarded. Trends favour momentum; ranges favor mean reversion. Acting too early often turns a potentially profitable idea into a costly one. Systematic tools assist timing entries with greater precision.
