Momentum vs Value Investing: Which Wins? (2026)

Momentum vs value investing — how each works, the evidence for both, when each shines, and how to combine them. A clear, no-hype comparison.

StocksStrategyInvesting

Momentum and value are the two most studied "factors" in investing — and they work in almost opposite ways. Value buys what's cheap and unloved; momentum buys what's already winning. Both have decades of evidence behind them, and both go through long stretches of underperformance. So which should you use? This is an honest comparison of how each works, when each shines, and why the answer might be "both."

What is value investing?

Value investing buys stocks that look cheap relative to fundamentals — low price-to-earnings, price-to-book, or high dividend yield — on the thesis that the market has underpriced them and they'll revert upward. It's the philosophy of Graham and Buffett: pay less than something is worth.

  • Edge: buying undervalued assets that recover.
  • Weakness: "value traps" (cheap for a good reason) and long dry spells when growth dominates.

What is momentum investing?

Momentum buys stocks that have been going up, on the thesis that trends persist for a while as the market catches up to news. It's rules-based and trend-following rather than valuation-driven. We cover it in depth in our momentum investing guide.

  • Edge: riding established trends; one of the most persistent documented anomalies.
  • Weakness: "momentum crashes" after sharp market reversals, and higher turnover.

The evidence: both are real

Here's the surprising part — both factors have delivered long-run outperformance in academic studies across decades and markets. They're not competing theories where one is "right." They capture different behaviours: value exploits overreaction (things get too cheap), momentum exploits underreaction (news prices in slowly).

Crucially, momentum and value are negatively correlated — they tend to do well at different times. Value shines in recoveries and rotations; momentum shines in sustained trends.

When each shines

  • Momentum wins in trending markets — strong bull runs, clear sector leadership.
  • Value wins at turning points — after a crash, in a rotation from expensive to cheap.
  • Both struggle in choppy, directionless markets.

Trying to time which factor is "on" is hard. That's why many investors don't choose — they combine.

Why combining beats choosing

Because value and momentum zig and zag at different times, holding both can smooth the ride: when momentum is crashing, value is often recovering, and vice versa. A blended, rules-based approach captures both premia with less stomach-churning drawdown than either alone.

If you'd rather run one disciplined sleeve well than juggle both, a rules-based momentum portfolio is a clean, low-effort way to capture one proven factor — see how we build ours in EXCAVO STOCKS (~20 S&P 500 momentum stocks, rebalanced monthly; backtested results are historical and not a guarantee).

FAQ

Is momentum or value investing better?

Neither is universally "better" — both have long-run evidence and both underperform for years at a time. They shine in different conditions, which is why many investors combine them.

Why are momentum and value negatively correlated?

They exploit opposite behaviours: value profits when overreaction makes things too cheap; momentum profits when underreaction makes trends persist. They tend to work at different points in the cycle.

Can I use both at once?

Yes — a blended approach can reduce drawdowns because the two factors tend to offset each other's weak periods.

Conclusion

Momentum vs value isn't a fight with a winner — it's two proven, complementary edges that work at different times. Pick the one whose logic you'll actually follow, or combine them to smooth the ride.
