Alphanume

Alphanume — Point-in-time equity-registration / dilution event dataset built from EDGAR: every S-1-family registration statement is stamped with its filing date as the event date and carries the issuer's market cap as of one trading day before the filing, shares registered in the filing, and four vendor-created classification flags — dilutive versus not, resale versus new supply, effective once declared effective, and withdrawn with the withdrawal date. Lifecycle fields (effective date, days-to-effective, days-to-withdrawal) plus exact Eastern-time filing timestamps let a filing be reconstruc…

Alphanume offers (Alternative, Price, Reference, Fundamental) — 28 datasets in the catalogue, each a separate point-in-time table; the dilution SKU covers the full US registration-statement stream (S-1-family filings across all EDGAR filers), which historically implies order tens of thousands of filing-event rows with 10-plus documented columns each plus derived lifecycle and sizing fields. The public preview exposes only the last several days (a 6-row window spanning 28 September to 1 October 2026), so the visible slice understates licensed depth.

Short-candidate screens from dilutive filings with resale excluded, ranked by shares offered against market cap at filing (the vendor's stated primary workflow); long-book filtering so no position is carried unknowingly into a registered offering; event studies using the filing date as the event with same-window non-dilutive rows as controls; small- and mid-cap capital-structure risk monitoring; supervised learning on the pre-built dilutive-versus-non-dilutive and resale labels; and backtesting on genuinely point-in-time data — the scarce property here, since the dataset stores the pre-filing market cap rather than the current one
