The Nikkei Stock Average, also known as the Nikkei Index, is a price-weighted index consisting of 225 leading companies listed on the Tokyo Stock Exchange (TSE). Managed by the Nihon Keizai Shimbun (Nikkei) financial newspaper group, the Nikkei Index provides critical insights into the performance of the Japanese equity market.
Historical Context
The Nikkei Stock Average was first calculated on September 7, 1950, retroactively calculated to May 16, 1949. It quickly became one of the most-watched indices, serving as a barometer for Japan’s economic health.
In late 1991, a significant restructuring aimed to reduce the influence of futures-related trading. This restructuring was historic as it marked the first such adjustment and introduced an annual review of the index’s membership.
