TOKYO — Nikkei 225 recorded 64,136.25, +0.33% versus the provider previous close, for the completed 2026-09-17 cash session. The observation came from Yahoo Finance public chart. Nikkei 225 data time is retained separately from CapKet’s later publication time, preventing an editorial timestamp from masquerading as a market tick.

Nikkei 225: How to read this instrument
Because the Nikkei is price weighted, a high-priced constituent can affect the headline more than a much larger company with a lower share price. The yen, exporters and chip-related shares are useful follow-up checks, but the index move alone does not prove which input dominated.
the instrument owner’s reference page supplies the formal identification. The reference page fixes what Nikkei 225 represents. That boundary prevents a related derivative, spot series or consumer price from being silently substituted.
Nikkei 225: Checks before the next report
Compare the closing auction with Tokyo breadth and the yen before assigning a cause; keep the cash index separate from CME Nikkei futures.
CapKet will not assign a Nikkei 225 cause until a dated primary record overlaps the move closely enough to support the claim.
