As each period's own 10-K or 10-Q reported it
At the $33.34 close on Oct 9, 2026, against 256.04M shares and the balance sheet at Jun 28, 2026; earnings, sales and cash flow over the four quarters to Jun 28, 2026. A ratio is left out where its denominator is not positive. Fair value is the company's own median P/E, price to sales and price to free cash flow at its last ten fiscal year ends, applied to its trailing figures, the middle of the three: its valuation against its own past, not against its growth or its rivals.

Figures come from the company's XBRL filings as the SEC publishes them. Quarters are worked out from year-to-date figures, and a fourth quarter is the year less its first nine months, which is why it has no EPS: per-share figures do not subtract. Earlier years are on today's share basis where a split has happened since. A later restatement is not mixed into a year it was never applied to, so where a 10-K restated the year before — a business sold, say — that year's fourth quarter is left blank rather than worked out across two bases. A dash means the company did not report that line under a standard tag for that period. Every filing on EDGAR.

Short interest is every broker's short position at the settlement date, reported to FINRA and published about a week and a half later; it does not say who is short. Days to cover is the short position over the average day's trading, and the share of the company is against the shares outstanding on its latest filing. A fail to deliver is the balance of shares sold and not delivered by settlement, from the SEC: it can be a short seller who never borrowed the stock, but is as often a late delivery that clears within days.
