Valuation State vs. Action Label: Why "Expensive" Does Not Mean "Sell"
"This stock is expensive" and "you should sell" are two different things. The engine separates "what it is worth" from "what you should do."
Beginners often read "this stock is judged Expensive" as "the engine is telling me to sell." In fact the engine deliberately separates two things: the valuation state (what it is worth) and the action label (what you should do).
Valuation State: Purely Mechanical
The valuation state (deeply undervalued / undervalued / fairly valued / somewhat expensive / expensive / bubble territory) is determined mechanically by the Return Spread, with no subjectivity mixed in. It describes "whether the return from buying at the current price is enough relative to your pass/fail bar"—an objective characterization of the asset itself.
Action Label: Layering in Your Situation
The action label (buy / hold / do not add / trim / avoid, and so on) sits on top of the valuation state and further considers: whether you already hold it, how large the position is, portfolio concentration, downside risk, and the reliability of this particular conclusion. The same "expensive" verdict might be "wait and watch" for someone with no position, and "consider trimming" for someone heavily concentrated—while for a great company judged "expensive," a long-term holder may perfectly well choose to keep holding.
“Valuation answers "what it is worth," action answers "what you should do right now"—do not conflate the two.”— Institutional Research Principle
Why This Matters
Separating the two avoids two kinds of error: buying mindlessly because something is "cheap" (ignoring position size and downside), or panic-liquidating because something is "expensive" (ignoring taxes, frictions, and the fact that it is still a good company). The engine gives you an objective characterization of value and leaves the final judgment of "what to do" to rational decision-making that accounts for your situation.
How It Shows Up in the Report
The report gives both the valuation state and the action label, and explains why the action label is constrained by position / risk / reliability. Once you grasp this distinction, you will not misread the word "expensive."
The valuation state is a mechanical "expensive/fair/cheap"; the action label further layers in your position, portfolio, risk, and reliability—the two must not be conflated.
Put the discipline to work—let the engine produce an auditable, institutional-grade valuation of a US stock.
