The Nikkei 225 is a stock price Index published by Nikkei Digital Media, Inc. It is calculated as the average price of 225 representative stocks traded on the first section of the Tokyo Stock Exchange. The Nikkei 225 is calculated by adjusting the divisor to maintain continuity as needed, using the same method as the Dow Jones Industrial Average.

The current calculation method was first adopted in 1950, and the Index is calculated retroactive to 1949. The Nikkei Stock Average has the longest history among stock indices in Japan, and is well known by investors and others concerned with the stock market in Japan and around the world. The 225 components are reviewed annually based on market liquidity and sector balance criteria. In addition, they are reviewed in response to mergers or delisting of component issues.
