Earnings Quality	20/100
Balance Sheet	81/100

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

16 quarters, 23 Q1 to 26 Q4. Peak 70 in 26 Q4, latest 70 — +0 since. Fell in 2 of the last 4 quarters. Dashed line marks 40 on the 0-100 scale.

BUSINESS QUALITY70 / 100IS Score 69.9 / 100 · +0.0 from peak of 70

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

PRICE STRUCTUREBEARISHTechnical Score 16 / 100 · Power -67 · 2 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.

These two disagree — business quality 70, price structure 16 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.

Trigger	Where it stands now	What it would mean
IS Score reaches 75 and holds two consecutive quarters	now 69.9	would move us up one band
IS Score stops falling - one quarter higher than the prior	last four: 63 → 62 → 66 → 70	the direction matters more than the level
Technical vote share back above 50%	now 9%	price structure no longer broken
Institutional holder count rises two quarters running	peak 1,857 → now 1,857	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 2025-09 reads 100.27%. Institutions cannot hold more of a company than exists. The reported 345.9M shares exceed the 345.0M outstanding, and a single filer accounts for the excess: VANGUARD GROUP INC reports 43,282,393 shares against 43,039,216 the prior quarter, a 1x jump, which alone would be 12.5% of the company. Excluding that filing, ownership is 87.7%. 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.

Why 2025-06 reads 105.92%. Institutions cannot hold more of a company than exists. The reported 365.4M shares exceed the 345.0M outstanding, and a single filer accounts for the excess: VANGUARD GROUP INC reports 43,039,216 shares against 42,938,495 the prior quarter, a 1x jump, which alone would be 12.5% of the company. Excluding that filing, ownership is 93.4%. 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.
