What a Calculation Date Tells You That a Score Cannot

A stock score without a date is a photograph without a timestamp. It may be accurate, but you cannot tell whether it shows this quarter or the last one. The calculation date is the smallest piece of metadata on a score and, in practice, the one that prevents the most mistakes.

Two inputs, two clocks

A sector-relative score mixes two kinds of data that age at different speeds. Prices refresh every trading day, so the momentum pillar is never more than a day old. Fundamentals refresh only when a company files, so the quality, safety, valuation and growth pillars can sit unchanged for three months and then jump in a single day. A score computed the day before a filing and a score computed the day after can differ sharply while the price has barely moved.

Three questions the date answers

Is the fundamental half stale? If the calculation date is earlier than the company's most recent quarterly report, four of the five pillars are describing the previous quarter. Treat the total as provisional until it is recomputed.

Are two scores comparable? Comparing a stock scored on Monday with a peer scored three weeks later is comparing two different snapshots of the sector. The ranks were computed against different peer distributions. Only scores with close dates should be ranked against each other.

Did the score change, or did the data? When a score moves and the price did not, the date lets you check whether a new filing, a restatement or a data-provider correction is the cause, rather than a change in the business.

Why free data makes this more important, not less

Free and low-cost data sources post fundamentals days or weeks after the filing, and they occasionally restate earlier figures. A platform that hides the calculation date hides that lag. A platform that shows it lets the reader decide whether the number is fresh enough for the decision at hand.

On Stock Expert AI, every MoonshotScore is published with its calculation date next to the five pillar scores, and the refresh rules for each input are described on the methodology page.
