Nikkei 225

Price-weighted index of 225 large Japanese companies listed on the Tokyo Stock Exchange Prime Market, dating back to 1950 and calculated by the Nikkei newspaper group since 1970. It is Japan's most widely quoted equity benchmark.

This asset is calculated on the venue linked above — a typed relationship in the dataset, not a name that happened to match. The parties named after it (Nikkei Inc. (index provider)) matter to how it trades but are not entities here.

No live level is shown for this asset: our open, keyless sources cover crypto, major FX crosses, the ECB policy rate, the US 10-year yield and US CPI — index levels and commodity prices are only available from licensed vendors, and we do not publish figures we cannot source openly. What we do carry.
