  "account": "The Tokyo Stock Exchange plans to overhaul its Topix index, reducing the number of constituent stocks by nearly 40 percent to under 1,000. This change aims to attract more investment, according to the exchange operator. Starting October 30, the weighting of 683 stocks currently in the index will be decreased on a quarterly basis, while 35 new companies, such as McDonald's Japan and Toei Animation, will be added on the same day. Stocks that fail to meet the criteria during a reassessment in October 2027 will be permanently removed by July 2028. The selection of stocks will be based on factors like market capitalization and trading volume. Initially, the Topix index included all stocks listed in the First Section of the Tokyo Stock Exchange. However, after a market reorganization in 2022, these stocks were reclassified primarily into the newly created Prime Market. Beginning October 2028, the index's constituent stocks will be reviewed and replaced annually.",
