QS fell -2.9% at the last close
No obviously market-moving filing before this close. The nearest headline, “QuantumScape reports narrower Q3 loss, plans 100-MWh battery production line”, was published Oct 22, 5:24 a.m. ET, before the previous close, so earlier sessions saw it too. The 10-Q (quarterly report) was accepted 4:07 p.m. ET on Oct 23, after the close, so it cannot have caused this move.
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.
