Nikkei 225
a.k.a. Nikkei, JP225
Japan's best-known stock index, tracking 225 big companies listed in Tokyo.
In plain English
Japan's best-known stock index, tracking 225 big companies listed in Tokyo.
The Nikkei 225 follows 225 large companies on the Tokyo Stock Exchange. Unusually, it is price-weighted: a company with a high share price moves the index more than one with a low share price, regardless of how big the company actually is.
It has a famous yen connection. A weaker yen makes Japan's exporters' overseas profits worth more at home, so the Nikkei often climbs when USD/JPY rises, and vice versa.
