How to Read a 0-100 Stock Score Without Fooling Yourself

A single number is seductive. Give an investor a stock score between 0 and 100 and most will treat 82 as "good" and 31 as "bad" without asking the only question that matters: good compared to what?

This post is a short field guide to reading composite stock scores, including the one we publish at Stock Expert AI, so that the number helps you instead of replacing your judgment.

1. Ask what the score is relative to

A score built on absolute thresholds (P/E under 15 is "cheap") will systematically favor banks and punish software. A score built on sector-relative ranks compares each company only to its own peer group. The second kind is comparable across industries; the first is not. Our own methodology page explains why every MoonshotScore input is ranked inside its sector before it is combined.

2. Look at the components, not just the total

Two stocks can both score 70. One is a 95 on momentum and a 45 on everything else. The other is a 70 across the board. They are different situations and deserve different position sizes. If a score does not show its components, treat it as a headline, not an analysis.

3. Check the date stamp

Fundamentals update quarterly, prices update every second. A score computed on two-quarter-old filings looks identical to a fresh one. Always find the "as of" date before acting.

4. Separate the AI from the arithmetic

When an AI model writes the commentary around a score, make sure it is not also inventing the numbers. We keep the two channels separate: figures are rendered verbatim from market data providers, and the model is only allowed to explain them. If a tool cannot tell you where its numbers come from, that is the answer.

5. Audit the score against outcomes

The honest test of any scoring system is what happened afterward. We published an audit of 6,213 of our own score records to show what a high or low score has historically meant. Ask the same of any score you use.

A score is a filter, not a verdict. Use it to shorten the list, then do the work on what is left.
