TOPIX facts via Wikinvest The index transitioned from a system where a company's weighting is based on the total number of shares outstanding to a weighting based on the number of shares available for trading (called the free float). This transition took place in three phases starting in October 2005 and was completed in June 2006. Although the change is a technicality, it had a significant effect on the weighting of many companies in the index, because many companies in Japan hold a significant number of shares of their business partners as a part of intricate business alliances, and such shares are no longer included in calculating the weight of companies in the index. The TOPIX index is traded as a future on the Osaka Exchange under the ticker symbol JTPX. The CQG contract specifications for the TOPIX Index are listed below. TSE currently calculates and distributes TOPIX every second and further plans to launch a new High-Speed Index dissemination service provided at the millisecond level starting from February 28, 2011.
