Tokyo, Japan – The Yomiuri Shinbun, a major Japanese newspaper, announced plans to launch a new stock index called "Yomiuri 333" in March 2025. This index aims to provide investors with a new benchmark for tracking the Japanese stock market.

The Yomiuri 333 will be composed of 333 leading Japanese companies and will employ an equal-weighting methodology. This means that the price performance of each of the 333 constituent companies will have an equal impact on the index, making it less susceptible to the influence of a few large or high-priced stocks.

In contrast, the existing TOPIX and Nikkei 225 indices use market-capitalization weighting and price weighting, respectively, making them more sensitive to the movements of large-cap or high-priced stocks. The Yomiuri 333, on the other hand, provides a more broad-based representation of the overall stock market.

This new index is expected to enable investors to gauge the long-term growth prospects of the Japanese economy. Furthermore, the development of investment products based on the Yomiuri 333 is anticipated to expand investment options for investors.

The Yomiuri Shinbun plans to promote the use of the Yomiuri 333 within the new NISA (Nippon Individual Savings Account) framework. The company also intends to develop investment trust products based on this index. By offering an index that aligns with long-term, diversified investing, the Yomiuri Shinbun aims to support investors in building their wealth over the long term.
