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.

IS Score Trend — quarterly

14 quarters, 23 Q1 to 26 Q2. Peak 57 in 26 Q2, latest 57 — +0 since. Fell in 1 of the last 4 quarters. Dashed line marks 40 on the 0-100 scale.

BUSINESS QUALITY57 / 100IS Score 57.0 / 100 · +0.0 from peak of 57

Fundamental factor model, quarterly. Measures how the business is doing - not where the price is going.

PRICE STRUCTUREBULLISHTechnical Score 87 / 100 · Power +74 · 21 of 22 indicator votes bullish

Vote share across trend, momentum, volume, volatility and pattern families. Describes where the price is, not where it is going.

Both readings sit above the midpoint — business quality at 57 and price structure at 87 out of 100 — so they are not in conflict. The fundamentals and the tape are saying the same thing, which is the case in which either one alone would have been enough.

Trigger	Where it stands now	What it would mean
IS Score reaches 75 and holds two consecutive quarters	now 57.0	would move us up one band
IS Score stops falling - one quarter higher than the prior	last four: 53 → 50 → 55 → 57	the direction matters more than the level
Technical vote share back above 50%	now 91%	price structure no longer broken
Institutional holder count rises two quarters running	peak 1,841 → now 1,754	fewer institutions willing to hold is our clearest warning

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 2025-12 reads 101.89%. Institutions cannot hold more of a company than exists. The reported 474.9M shares exceed the 466.1M outstanding, and a single filer accounts for the excess: VANGUARD GROUP INC reports 63,757,586 shares against 63,640,168 the prior quarter, a 1x jump, which alone would be 13.7% of the company. Excluding that filing, ownership is 88.2%. 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.
