Technical analysis tells you what the market is doing. Fundamental analysis tells you whether it should be doing it. A stock can rally on hype, but it can only sustain a rally with earnings, margins, and institutional backing.
The Research Foundation
Piotroski (2000) demonstrated that simple fundamental signals — earnings trends, margin improvement, balance sheet health — significantly predict future returns, especially among value stocks. Fama & French (2015) expanded their famous three-factor model to five factors, adding profitability and investment as return predictors.
The message is clear: fundamentals matter. Not as a standalone signal, but as a structural foundation that determines whether a technical setup has staying power.
Four Dimensions of Fundamental Quality
Alpha Pulsx evaluates fundamentals across four key areas:
- Valuation — Where does the stock sit relative to its own history and its sector? P/E, P/S, and PEG ratios in context. A high P/E in a high-growth sector means something different than the same P/E in a mature industry. We evaluate valuation relative to expectations, not in absolute terms.
- Earnings Quality — Not just whether the company beat earnings, but the quality of those earnings. Surprise history, guidance trajectory, revenue vs. earnings beats. A company that consistently guides up has a different fundamental profile than one that consistently disappoints.
- Margin Trends — Are profit margins expanding or contracting? Margin expansion is the hallmark of a company gaining operating leverage. Margin contraction, even with revenue growth, is a warning sign.
- Institutional Ownership — Who owns the stock, and are they buying or selling? Rising institutional ownership validates the thesis. Smart money moving out — even while price holds up — is an early warning that the fundamental story may be changing.
Fundamentals as a Filter
In our six-pillar model, fundamentals serve a critical filtering role. A technical breakout in a stock with deteriorating margins and falling institutional ownership has a much lower probability of success than the same breakout in a stock with expanding margins and rising ownership.
We don't use fundamentals to pick stocks. We use them to validate — or invalidate — what the other five pillars are telling us.
