What is momentum trading?
Momentum trading is built on a single observation: things in motion tend to stay in motion. Instead of fading a strong move like a mean-reversion trader, a momentum trader joins it — buying what's already rising, selling what's already falling — on the bet that the move persists a while longer.
Momentum overlaps with trend following but operates on a shorter, more immediate horizon: it's about the force of the current move. Traders gauge it with RSI, ROC, and Stochastic — though note the trap, since a high momentum reading means a move has been strong, not that it will continue.
The mirror of mean reversion
Momentum and mean reversion are exact opposites: momentum buys strength expecting more; mean reversion sells strength expecting a snap-back. They win in opposite regimes — momentum in trending, directional markets; mean reversion in balanced, ranging ones. Running the wrong one for the regime is the fastest way to lose, which is why a complete approach often combines both.
The risk: momentum reverses violently
Momentum's danger is that strong moves can snap back hard once they exhaust — the very extension that drew you in becomes the reversal that stops you out. Chasing late, after most of the move is done, is the classic error. Defined entries and stops are what separate a momentum edge from simply chasing.
How a system trades momentum
A system defines exactly what “enough” momentum is, enters mechanically, and exits by rule — never chasing because a move “feels” strong, never jumping in late out of FOMO. It takes the defined momentum setup identically every time, which is how the edge survives the violent reversals that punish discretionary chasers.
Momentum trading joins strong moves expecting continuation — the mirror image of mean reversion. It thrives in trends and gets punished by sharp reversals, so it lives on defined entries and stops, taken mechanically rather than chased.
