About and method

What this site is

TickerArchive is a day-by-day archive for tracked US stocks and ETFs. The question it answers is a common one in market research: a stock moved hard on some past day; what happened that day? Instead of hunting across a chart site, a filings site and a news search, the day card here puts the price move, volume, that day's SEC filings, insider filings and collected headlines on one page.

Sources

Prices and headlines: Yahoo Finance. Filings and insider transactions: SEC EDGAR, the US Securities and Exchange Commission's public filing system. Every filing entry links to the original document on EDGAR.

What is backfilled, what is collected forward

Prices and SEC filings are backfilled two years for each tracked ticker (forms tracked: 8-K, 10-Q, 10-K, 4, S-1, 424B5, SC 13D, SC 13G and DEF 14A). Volume ratio is the day's volume divided by the average volume of the prior 50 trading days.

News headlines are different: there is no honest way to reconstruct exactly which headlines ran on a past day, so headlines are collected forward starting November 9, 2026. Days before that show prices and filings only, and the day card says so.

Insider entries

Insider entries are filing-level: a Form 4 was filed that day, and the entry links to it on EDGAR, where the insider's name, role and transaction details appear in the document itself.

Update cadence

A collector runs after the US market close on weekdays. It adds the new trading day, new filings and the day's headlines to the archive. Archived days are append-only: once a day record is written, later runs add new days rather than rewriting history.

Not investment advice

TickerArchive is a research and reference tool. Nothing here is investment advice or a recommendation to buy or sell any security. Prices can contain errors; verify figures that matter against the primary source, which for filings is EDGAR.
