How to read a stock rating: what a score tells you and what it does not
A stock rating compresses many facts about a company into one number or one word. That is useful for comparing companies quickly, and misleading when it is read as more than it is. This guide explains what such a score is made of and how to read it with the right amount of trust.

What a rating is
A rating is a summary of facts that were true on a given date: how profitable the business is, how its price compares with its own history, what its financial position looks like. It describes the present and the recent past. It does not know the future, and it does not know you.
A good rating shows its date, shows its parts and says how it is built. If any of the three is missing, the number cannot be checked, and a number that cannot be checked deserves less weight.
How a composite score is built
Most composite scores work the same way. Each fact is turned into a sub-score on a common scale, for example 0 to 100, and the sub-scores are combined into one total by a method chosen in advance. Because the method is fixed, the same facts always give the same score, and a change in the score can be traced to the fact that changed.
Quality: how profitable the business is, how indebted, whether it produces free cash.
Valuation: what the market asks for the business compared with the company's own range over recent years.
Momentum, risk and liquidity: how the price has behaved and how easily it trades.
Outside opinion: what analysts as a group say, where a licensed source provides it.
Fit with a portfolio: how a stock's sector and country compare with the mix a person already has.
Words for ranges
Words such as Strong, Good, Neutral and Weak are only names for ranges of the score. A word says where the number falls, nothing more. It is not a statement about what to do, and two companies in the same range can look very different once their parts are opened.
What no rating can tell you
- Where the price goes next. A rating is not a forecast and not a probability.
- Whether a company suits your goals, your time horizon or your tolerance for loss.
- Events that have not happened yet: a lawsuit, a takeover, a change of management.
- How reliable the underlying data is for a small or foreign company with thin coverage.
How to use a rating sensibly
Compare scores of different companies on the same date, not a score today with a score from a different time.
Open the parts. A high total can come from one strong component while the others are weak.
Check the date of the data. An old rating describes an old situation.
Treat the rating as a place to start reading, and read the company's own reports for the rest.
Common questions
No. A score summarises facts that were true on a date. It is not a forecast and not a probability of any outcome.
They use different facts and different methods. The scores are comparable only inside one method, on one date.
A component without data is left out rather than guessed, and the score is built from the others; a score that rests on too little data is not shown at all.
