How to read these bars and different assessments

Council is a separate blend of available disciplines; MoonshotScore above remains the five-pillar research rating.

Bars show each model's ordered assessment on its own scale, not a probability or a comparable investment return. The adjacent words give the assessment; more filled segments indicate a stronger model reading.

On Apr 29, 2026, the Munger lens read the price at that time as fairly valued against its own estimate of value.

Readings on this page are from Oct 5, 2026, except a card that shows its own read date.

Sources — records for every figure on this page (19 figures)

The 19 rows below are exactly the facts the evidence-backed sections of this page printed — the 10-second verdict, the MoonshotScore, price and market value, the five questions with their receipts, and the records behind this page. Known dates and sources are recorded on their own rows; an em dash or UNRECORDED tier preserves a stored observation without inventing either. The quarterly income statement is provider-standardized (FMP) under one row, and scale definitions — a 0-100 rating, the band ladder, the Piotroski 0–9 range — are fixed rather than measured. No number in those sections was generated by a model. The register does not cover quoted third-party headlines, the dated council readings, or the Frequently Asked Questions; each of those says where it came from where it stands.

"As of" is the date the value is true for where the source carries one — a quarter end, a filing date, a price close, the day the score was computed. A cached observation with no source date remains undated; the page publication date is not used as a substitute.
