It is the oldest stock index in Asia, and the sheer size of the Japanese economy makes the Nikkei 225 a key measure of stock market activity in Asia. It has been calculated daily by the Nihon Keizai Shinbun (The Nikkei) newspaper since 1950. It is a price-weighted index, operating in the Japanese yen, and its components are reviewed once a year.Nikkei 225 was introduced in 1950, but it was retroactively calculated to May the previous year. Originally, the index was administered by the Tokyo Stock Exchange, but was taken over by the Nikkei financial newspaper in 1970.Since January 2010, the index is updated every 15 seconds during a session.The index was established as part of the rebuilding and industrialisation of Japan after the Second World War. Constituent stocks are ranked by share price, rather than by market capitalisation, as is common in most indexes, while valuations are denominated in Japanese yen. The composition of the Nikkei is reviewed every September, and changes take place in October.
