Which stock exchange is the primary venue for companies included in Japan’s Nikkei 225 index?

The Tokyo Stock Exchange is the primary venue for companies included in Japan’s Nikkei 225 index.

The exchange is Japan’s largest securities marketplace and is operated by Japan Exchange Group. Its listed companies include many major Japanese corporations, although the Nikkei 225 is an index of selected stocks rather than a complete list of every company traded there.

The Nikkei 225 is maintained by Nikkei Inc. and tracks 225 prominent companies listed on the Tokyo Stock Exchange’s Prime Market. It is price-weighted, meaning companies with higher share prices have greater influence on its movements.

A common mix-up is confusing the Nikkei 225 with the broader TOPIX index. TOPIX covers companies on the Tokyo Stock Exchange’s Prime Market using a free-float-adjusted market-capitalisation method, while the Nikkei 225 is a price-weighted index.
