How to use this page

Financial shorthand is compressed rather than complicated. Almost every term below is a ratio, and almost every ratio is one number divided by another number that puts it in context.

If you meet an unfamiliar abbreviation anywhere on Pythia, it is here, and the metric popover on the number itself carries the same definition plus the inputs that produced that specific value.

Three that cause the most confusion

TTM and LTM mean the same thing — trailing (or last) twelve months. They exist because a fiscal year is an accounting convenience and rarely ends when you happen to be looking. A TTM figure sums the last four reported quarters, so it is always current to the most recent filing rather than to a year end.

Enterprise value is not market cap. Market cap prices the equity; enterprise value prices the whole business by adding debt and subtracting cash. Two companies with identical market caps can have very different enterprise values, and any multiple built on EV is comparing something different from one built on price.

A z-score is a position, not a quality. It says how many standard deviations a value sits from the mean of its comparison group. It carries no opinion about whether high is good — that depends entirely on the metric, and it is why a low valuation z-score is favourable while a low profitability z-score is not.

Where the sector labels come from

Sector and industry on Pythia follow GICS, the classification MSCI and S&P maintain jointly. It matters more than a taxonomy usually would, because every sector-neutral comparison — the z-scores behind PAS, the peer sets behind percentile ranks — is computed within a GICS sector and country.

Companies we cannot classify are marked Unclassified and get no PAS — rather than being placed in a peer group they do not belong to, or scored by some other method that would not mean the same thing.

Check yourself

4 questions. Nothing is recorded unless you are signed in, and nothing here affects anything else.

1. Why is enterprise value, rather than market cap, the right measure of what a whole business would cost to own?
2. A stock's valuation z-score within its sector is -1.5. What does that tell you?
3. The company already reports a full fiscal year. Why does a TTM figure exist at all?
4. A company cannot be classified into a GICS sector. Why does it get no PAS at all, rather than a score computed some other way?

4 questions left. An unanswered question counts as a miss, so the check waits for all of them.
