STRK was little changed (-1.7%)
No obviously market-moving filing before this close. The nearest headline, “Strategy rises for second straight session, climbing 8%”, was published Oct 21, 5:38 p.m. ET, before the previous close, so earlier sessions saw it too.
End-of-day prices (Databento) + SEC EDGAR filings + headlines. We surface the real signals on file and name the likely driver — correlation, not a guaranteed cause. Filings are placed by the time EDGAR accepted them and headlines by when they were published, so anything that went public after the close is marked after the move and never named the driver. Not investment advice.
