Momentum Investing

Momentum investing buys assets that have been rising and avoids those that have been falling, on the well-documented tendency for trends to persist.

In one line: Momentum investing buys assets that have been rising and avoids those that have been falling, on the well-documented tendency for trends to persist.

What it is

Momentum investing is the strategy of buying what's strong and avoiding (or shorting) what's weak, based on one of the most robust findings in finance: over intermediate horizons (roughly 3–12 months), winners have historically tended to keep winning and losers to keep losing. It is the disciplined cousin of 'the trend is your friend.'

How it works

A systematic momentum approach ranks a universe by trailing return or relative strength, buys the top performers, and periodically rebalances — rotating out of names that lose their leadership. It's the opposite instinct of value investing, which buys what's cheap and out-of-favor.

Momentum is closely tied to trend and breakout techniques on shorter timeframes, and to breadth for gauging whether momentum is broad or narrow.

Worked example

Example

A simple monthly momentum rule: rank the large-caps in an index by their trailing 6-month return, hold the top 20%, and re-rank each month. A name that has led for two quarters stays in the basket until its relative strength fades and it drops out of the top group. The system never tries to call a bottom — it simply follows leadership and cuts laggards, letting the trend do the work.

Why it matters

Momentum has been documented across decades, countries, and asset classes — it's one of the few effects with strong academic support. But it carries a specific danger: momentum crashes. When leadership violently reverses (often at market turning points), momentum strategies can suffer sharp, fast losses. That's why exit discipline and sizing matter as much as the entry.

FAQ

Is momentum investing the same as day trading?
No. Momentum is a strategy about direction persistence and can be applied over any horizon — from multi-month systematic rotation to shorter swing trades. Day trading is about holding period (intraday). You can trade momentum on a monthly rebalance or across a few weeks.
What is the biggest risk of momentum?
Sharp reversals — 'momentum crashes.' Because momentum buys what has already risen, it is most exposed when a strong trend suddenly reverses, which tends to happen fast at market turning points. Risk management (stops, sizing, diversification) is what makes momentum survivable.
