The Tokyo Stock Exchange (TSE) has today trimmed the interval of real-time dissemination of TOPIX, and its sub-indices(“Indices”)*(1) to securities firms, news media, information vendors, etc. through the Market Information System from 15 seconds to 1 second *(2).
TOPIX, etc. are widely used as indicators of price movements in the Tokyo stock market. With this improvement, these indices will reflect market movements in a more timely manner, thereby enhancing their function as indicators.
In addition, the TSE plans to launch a new High-Speed Index Dissemination Service in February 2011, which provides millisecond-level distribution of TOPIX and other indices calculated and published by the TSE.
*(1) Indices: TOPIX, TOPIX Core30, TOPIX 500, TOPIX 1000
*(2) After this improvement, indices calculated by TSE other than those
mentioned above will be disseminated at the same 15-second interval as currently
employed.
