A reform is under way to advance the replacement of TOPIX constituents, ultimately narrowing the number of constituent companies from approximately 1,700 to around 1,000. The aim is to establish an investment vehicle that is not overly dependent on the Nikkei Average, expand individual wealth-building, and encourage investment in the Japanese economy as a whole.
The Tokyo Stock Price Index (TOPIX) has begun a major overhaul, with a policy outlined to narrow its constituents from the current approximately 1,700 stocks to around 1,000 in the end. The aim is to reselect companies representing Japan based on criteria such as trading activity and free-float market capitalization.
The true significance of the reform is said to lie not simply in replacing constituents, but in creating an investment vehicle to direct Japan’s vast pool of household financial assets toward the growth of Japanese companies. The backdrop is the spread of the New NISA, and the reform also seeks to correct the Nikkei Average’s susceptibility to price movements in particular sectors.
What lies beyond the reform is an expanded role for TOPIX-based indices as a new investment vehicle and the development of a market environment that directs growth capital for Japanese companies into the domestic market. The first installment explains the background and significance of the reform, while related information has drawn attention to developments ahead.
The pitfalls of the Nikkei Average, and the TOPIX reforms intended to complement it, are said to have the potential to change the way investors approach Japanese stocks. The finalization of the official constituent composition and the market’s response will continue to attract attention in subsequent reports.
