For nearly 60 years, Nikkei has calculated the Nikkei 225, the most widely followed index of the Japanese stock markets. Calculated continuously since September 1950, the Nikkei 225 consists of 225 of the most liquid companies in the 1st section of the Tokyo Stock Exchange. In 1993, Nikkei launched the Nikkei 300 index, a market capitalisation index for the Tokyo Stock Exchange. As the calculators of the Nikkei indices, we provide data of the highest accuracy for index benchmarking and tracking.

Nikkei supplies the data to calculate the indices via NEEDS BULK and via our third party supplier MarkIT. We provide daily constituent pricing, number of outstanding shares, index divisor and index value in either NEEDS BULK format, which can be used to populate proprietary databases or systems, or via an existing MarkIT connection.

We also supply data covering Nikkei derivatives traded on the Osaka Security Exchange - such as Nikkei 225 Futures and Options. Data for Nikkei index derivatives is available via NEEDS BULK or NEEDS Financial QUEST.

The index is different to market capitalization 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 capitalization 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 to ensure that events such as stock splits, dividends and changes in constituents do not distort the index.

The divisor value is published along with the price values of the Nikkei constituents
