For over 60 years, Nikkei has calculated the Nikkei Stock Average (Nikkei 225), the most widely followed index of the Japanese stock markets. Calculated continuously since September 1950; by Tokyo Stock Exchange (TSE) until 1970, the index consists of 225 of the most liquid companies in the 1st section of the TSE. And in 1993, Nikkei launched the Nikkei 300 index, a market capitalisation index for the TSE.

As the calculators of the Nikkei indices, we provide data of the highest accuracy for index benchmarking and tracking; daily constituent pricing, weights, number of outstanding shares, index divisor and index value. These data are supplied via NEEDS BULK format, which can be used to populate proprietary database or system, or via Nikkeifs third party supplier Markit, a leading global provider of financial information services.

Nikkei 225 Index Calculation
The index is different to market capitalisation indices such as the S&P 500 or the FTSE100, which take into account the price and number of outstanding shares, so that the index value is affected more by market capitalisation movements from larger companies. Cash weighted indices such as the Nikkei 225 or the Dow Jones Average take just the share price and its predetermined par value. The par value* is used as a base for the shares, which for most stocks in the Nikkei 225 is 50 yen; stocks with a different par value have their share price converted to a 50 yen par value base. A divisor is then used to ensure continuity in the index; events such as stock splits, dividends and changes in constituents do not distort the index. 

* Due to the revision of Commercial Law in Oct. 2001, "Par Value" system was abolished. For this reason Nikkei uses “presumed par value” which succeeds the ex-par value and adjust the constituent prices to the presumed par value of 50 yen base.
