Each component is a diagnostic reading on its own 0-100 scale. The overall score is computed separately from the underlying financials and is not the average of the rows above — components are not equally weighted and three of them (Momentum, Value, Risk) are derived partly from price rather than from the business.

These two disagree — business quality 62, price structure 24 out of 100, so the business reads better than the price does. We publish the disagreement rather than resolving it: they answer different questions, and the gap between them is information, not an error.

TriggerWhere it stands nowWhat it would mean
IS Score reaches 75 and holds two consecutive quartersnow 62.4would move us up one band
IS Score stops falling - one quarter higher than the priorlast four: 74 → 68 → 66 → 62the direction matters more than the level

We publish these so the view can be shown to be wrong. If none of them move and our reading does, we owe you an explanation.

How to read ownership above 100%. A 13F reports the positions a manager has investment discretion over, and where two or more managers share discretion over the same block, each one reports it. Summed across filers, the total can therefore exceed the shares actually outstanding without anything being wrong. We publish the figure as filed rather than netting it down, and flag separately any quarter where the arithmetic is not merely high but impossible.

Why 2025-09 reads 141.52%. Institutions cannot hold more of a company than exists. The reported 69.5M shares exceed the 49.1M outstanding, and a single filer accounts for the excess: Lombard Odier Asset Management (Europe) Ltd reports 22,690,966 shares against 12,716 the prior quarter, a 1,784x jump, which alone would be 46.2% of the company. Excluding that filing, ownership is 95.3%. We publish both figures. 13F filings are due 45 days after quarter end and amendments keep arriving after that, so the newest quarter is provisional by construction - this is what an unsettled quarter looks like.

Method. Every figure in this factsheet is looked up from a named field computed in code. It contains no model-written text.

Not covered. Short interest as a percent of float and days-to-cover are not in this data set — the short-sale figures above are FINRA volume, a flow, and cannot support squeeze or covering analysis. Options positioning and intraday data are also absent. 13F ownership is filed 45 days after quarter end and congressional trades are disclosed on a lag, so both describe a past position, not a current one.
