On August 7, 2026, Nikkei and JPX Market Innovation & Research announced revisions to the JPX-Nikkei 400 and the JPX-Nikkei Mid and Small Cap Index. The JPX-Nikkei 400 will add 45 stocks, including T&D Holdings and Furukawa Electric, while removing 39 companies like KDDI and Asahi Group Holdings. The Mid and Small Cap Index will add 49 stocks and remove 43. The changes, effective August 31, reflect an annual review process where additions typically outweigh removals due to some companies having been excluded previously. The index updates occur annually in late August.
