Dated prices, transparent estimates. SEC fund snapshots provide reference prices for 502 of 503 stocks. Price-dependent methods use estimated issuer market caps where share counts can be matched. Prices are historical, not live; 12–1 momentum is shown only where the dated endpoints and stock-split history have been reviewed. Understand coverage ↗

ⓘ9 of 503 listings have all 12 method results. ACN, ADBE, AMAT, CSCO, KO, GILD, HD, MA, MSFT. Other listings have missing inputs or methods that do not apply. A blank result never means zero; the table below shows actual coverage for every method.

Reference prices · SEC fund holdings

SPDR S&P 500 ETF Trust, Schwab and Vanguard N-PORT reports supply dated level-1 stock valuations. We divide USD holding value by the number of shares held. Issuer market caps are approximate: price multiplied by SEC outstanding shares from the same date or up to 100 days earlier. Reviewed share classes use dated counts and explicit economic-equivalence rules. Where listed classes have separate prices, their values are summed. Other reviewed classes use disclosed price proxies. Ambiguous classes remain excluded. Older observations use their own dated share counts; no current shares are applied backwards. Separate, date-limited split reviews enable fund-snapshot momentum for a small verified group. Other unadjusted observations remain excluded until corporate actions are checked.

JSON: records → ticker → asOf, adjustment (split or totalReturn), marketCap (USD), shares (units), history [{date, adjustedClose, marketCap}]. Dates must ascend. Market caps must cover the whole issuer.

Published records marked as historical snapshots remain usable with their dates displayed. Personal imports can opt into the same behavior with snapshot: true; otherwise market inputs older than ten days are excluded. Peer comparisons require price dates within ten days of one another. Historical multiples need at least three annual market caps. 12–1 momentum needs split-adjusted observations at the 12-month and 1-month cutoffs, plus the formation-date anchor. Month-end anchors use month-end cutoffs.

How gaps are handled

Alternative SEC tags and reviewed, sourced corrections improve coverage. Missing fields are preserved, rather than filled with zeros. A company with a new legal entity or a spin-off can lack comparable annual history. Not every unavailable metric is repairable through more searching; sector exclusions and nonpositive cash flows are intentional.

Current known gaps and manual research findings are recorded in the repository coverage audit. No paid data subscription is required to use the filing-based website. See the methodology before interpreting a scenario as fair value.
