The problem with naked momentum
Price momentum works (see Understanding momentum investing), but on its own it is indiscriminate. Rank the entire market by trailing return and the top of the list mixes two very different kinds of stock:
- Durable businesses in a real uptrend — profitable, growing companies whose shares are leading the market because the business is genuinely compounding.
- Speculative lottery tickets — pre-profit, cash-burning, story-driven names that have tripled on hype. Some keep running; many give it all back.
A pure-momentum book buys both. The lottery tickets add wild volatility and are the first to collapse when sentiment turns. The fix is not to abandon momentum — it is to gate it.
The quality gate
Before momentum ever ranks anything, a stock must clear a durability screen. We require a name to be a real, financially healthy business:
- Size: roughly $2B+ in market value — large enough to be liquid and established.
- Profitable: positive net income and positive free cash flow. Real earnings, real cash.
- High returns on capital: double-digit return on equity — evidence the business compounds capital well, not just grows for growth's sake.
- Growing: revenue actually increasing.
- Sound balance sheet: leverage kept in check, so a downturn doesn't threaten solvency.
Everything that fails the gate — the cash-burners, the over-levered, the shrinking — is removed from consideration. What remains is a pool of genuinely good businesses. Then momentum ranks them.
Why the combination beats either piece alone
Quality and momentum are a natural pair because their weaknesses cancel:
- Momentum fixes quality's timing problem. A wonderful business can stay unloved for years. Momentum waits for the market to start agreeing — you buy the great company when its stock is already working, not while it languishes.
- Quality fixes momentum's junk problem. The gate removes the speculative names that produce momentum's ugliest crashes, leaving trends backed by real earnings and cash flow.
In our own out-of-sample testing across multiple market regimes, ranking quality names by momentum beat the broad market by a meaningful margin, with a better risk-adjusted return — and crucially, it held up in the momentum-led bull runs where a cheapness-only approach lagged badly. The two signals are close to orthogonal: quality tells you what is worth owning, momentum tells you when the market has started to reward it.
Managing the risk
The combination is not magic, and momentum's reversal risk doesn't disappear — so two guardrails matter:
- Theme diversification. Momentum naturally clusters in whatever is hot — and concentration in one theme is exactly where momentum crashes hardest. We cap the bucket at two names per broad sector, forcing at least three distinct themes even when one corner of the market is on fire.
- An honest, forward track record. Back-tests flatter every strategy. The only defensible evidence is live, un-back-dated results, so each pick is logged at its pick-time price and tracked openly on our track record.
Bottom line
Quality momentum is a simple, durable idea: start with businesses worth owning — profitable, growing, cash-generative, well-capitalized — and among those, buy the ones the market is already rewarding. The quality gate strips out the lottery tickets that give momentum a bad name; the momentum ranking solves the "great company, dead money" problem that plagues pure quality and value investing. Diversify across themes, respect the reversal risk, and let the Momentum Leaders compound.
