Nikkei announced on September 4, 2026, that it will revise the constituents of the Nikkei 225 index as part of its regular review, effective October 1. The changes include the addition of JX Advanced Metals, Kokusai Electric, and Capcom to the index, while Archion, Konica Minolta, and Kanadevia will be removed [1]. The inclusion of JX Advanced Metals and Kokusai Electric is attributed to their market liquidity, whereas Capcom's addition aims to improve sectoral balance within the index [1].
In conjunction with the Nikkei 225 review, Archion and Konica Minolta will also be removed from the Nikkei 225 Climate Change 1.5°C Target Index (EU PAB) on October 1. Additionally, Konica Minolta will be dropped from the Nikkei 225 Global Exposure 50 Index on the same date [1].
The announcement reflects Nikkei's ongoing efforts to maintain the relevance and balance of its flagship index, with changes potentially impacting the market visibility and trading volumes of the affected companies. However, no specific market reactions, analyst opinions, or forward-looking statements were provided in the source article [1].
CONCLUSION
The Nikkei 225 will undergo constituent changes on October 1, with three companies joining and three being removed. The adjustments are based on liquidity and sectoral balance considerations. While the changes may affect the visibility and trading activity of the involved companies, no explicit market reactions or analyst commentary were mentioned.
