Inside the Momentum Stock Score: The Fundamental Filter

A price breakout is easy to spot after the fact. The harder question is: which breakouts are worth trusting, and which are noise? Before answering that, it helps to step back and look at how different investors approach the market in the first place.

Value investing looks for businesses trading below what they're believed to be worth, buying on the assumption that price will eventually catch up to intrinsic value. Growth investing does the opposite, paying a premium for businesses expected to grow revenue and earnings faster than the market, betting on where the company is headed rather than where it stands today. Quality investing cares less about either cheapness or growth rate and more about the durability of the business itself, strong returns on capital, low debt, a moat that holds up over time. Dividend investing prioritizes steady, often growing payouts from mature, cash-generative businesses, aiming for income over capital appreciation. High beta investing leans into stocks that move more sharply than the broader market, seeking amplified returns in exchange for amplified risk. Momentum investing does something different again: it follows strength that's already showing up, on the belief that a stock already in motion, backed by real demand, tends to stay in motion longer than the market expects.

Look closely at any of these approaches, though, and momentum is quietly the thing all of them are chasing in the end. Value investing is really a bet that price momentum will eventually catch up to a fundamental one. Growth investing is a bet that today's momentum in revenue and earnings continues into tomorrow's momentum in the stock. Quality investing bets that durable businesses eventually attract durable buying interest. Dividend investing is momentum of a slower, steadier kind, cash flow compounding quietly year after year. High beta investing simply amplifies whatever momentum is already present. Momentum investing is just the one approach that names this directly instead of arriving at it sideways.

But momentum without a foundation is just noise with a direction. The foundation, for us, is fundamentals, and reading them properly isn't something every investor can do at a glance. A rising sales number can mean genuine demand growth, or it can mean a company is discounting hard to move inventory. A profit spike can mean real operating leverage, or a one-time gain that won't repeat. Understanding which is which, and what it signals about a company's growth or the challenges building underneath it, takes a working knowledge of how a business actually functions, not just an ability to read a number on a screen. Fundamentals, read correctly, act as a barometer: they tell you whether the underlying business is genuinely strengthening or just putting on a good show for a quarter.

That's the layer our fundamental filter is built to test, before momentum ever enters the picture. It narrows a broad universe of stocks down to a shortlist worth watching for a technical trigger.

At a high level, the filter looks for businesses where sales and profit are both moving toward new highs together, not just one of the two, after a genuinely long stretch of quiet consolidation rather than a single good quarter. A one-off record is easy to dismiss as a fluke. A business steadily building toward new highs over several years, while its stock price goes nowhere or drifts sideways, is a very different story, and the market often hasn't caught up to it yet. That gap between quiet fundamental progress and a still-dormant stock price is exactly where this framework hunts.

Consistency matters more than any single number ever could. A business that spiked once off a large one-time order or an asset sale isn't what we're after. What earns a closer look is a trend that has genuinely been stepping upward, year after year, rather than lurching to a high point off one unusual year. The balance sheet gets checked too, because growth that's been financed with rising debt tells a very different story than growth that's actually been earned.

Why this order, and why fundamentals come first

Each of these checks works as a filter, not a score you can average your way past. A stock can look attractive on most of them and still get set aside if one reveals rising debt propping up the story, or a single freak year masquerading as a trend.

The purpose of running this filter before any chart is even opened is to remove the temptation to fall in love with a pattern first and rationalize the fundamentals afterward. Only once a name clears the filter does it earn a place on the shortlist, where a separate, purely technical trigger, a price breakout to a new all-time high, ahead of the broader index doing the same, decides if and when it's actually time to act. What happens after entry, including when a position is exited, is governed by its own separate set of rules, kept apart from this fundamental filter entirely.

Fundamentals decide whether a stock deserves attention at all. Price action alone decides when.

Updated every quarter, on purpose

This filter isn't a one-time pass. Every time quarterly earnings season comes around, the entire universe gets run through it again. A name that cleared the filter two quarters ago can quietly drop off if growth stalls or debt starts creeping up, and a name that wasn't ready before can newly qualify once its numbers catch up.

The effect is a shortlist that's constantly re-earned rather than grandfathered in. In practice, it works like picking the best of the best each quarter, businesses whose numbers are clean, whose growth is real, and whose fundamentals are still pointing the right way, quarter after quarter.
