Momentum Factor
The momentum factor captures “strength begets strength”: assets that outperformed over recent months tend, on average, to keep outperforming. One of the most thoroughly validated factors in both academia and live trading.
Momentum measures the persistence of returns: rank assets by their past 3–12 month performance, buy the strong, avoid (or short) the weak — and excess returns have historically shown up across equities, commodities, currencies, almost every asset class. Since being systematically documented in 1993, the effect has survived three decades of out-of-sample testing.
Why does it exist? The mainstream explanations are behavioral: investors underreact to news, so prices absorb good information gradually, creating drift; herding then amplifies the continuation. Because the root cause is human nature rather than a market glitch, momentum has proven hard to arbitrage away.
Its Achilles’ heel is the momentum crash: when markets snap into reversal — especially the violent rallies off bear-market bottoms — prior winners can lead the decline, handing momentum portfolios deep drawdowns. Mature momentum strategies therefore always pair with volatility control and cycle-state filters rather than running naked.
Within CycleMaster, momentum casts one vote in multi-factor resonance: a symbol in an Uptrend, ranking high on momentum, with macro at its back — that triple stack is precisely the high-confidence setup the system highlights. When momentum and cycle state diverge, the contradiction is surfaced explicitly instead of averaged away.
FAQ
Similar direction, opposite discipline. A momentum strategy has fixed ranking windows, holding periods, rebalance rules and risk controls; emotional chasing has no exit plan. Same phenomenon — one harvests it with rules, the other gets harvested.
The classic sweet spot is a 3–12 month formation window with weeks-to-months holding. Very short horizons (days) actually show reversal effects, and very long ones (3–5 years) drift toward mean reversion — momentum is a medium-term phenomenon.
