The level above is where the Nikkei 225, Japan's best-known stock index, is trading. Unlike most modern benchmarks it is price-weighted: the constituents with the highest share prices move the index most, regardless of how large those companies actually are. It also carries a strong currency link, because a weaker yen lifts the exporters that make up much of the index — which is why the Nikkei and the yen so often move in opposite directions.
What is the difference between the Nikkei 225 and TOPIX?
The Nikkei tracks 225 selected companies and weights them by share price, while TOPIX covers a far broader slice of the Tokyo market and weights by market value. TOPIX gives the better picture of the whole market; the Nikkei is the more quoted headline.
What does price-weighted mean?
Each stock's influence comes from its share price rather than its size, so a high-priced share can sway the index more than a much larger company with a low share price. The Dow Jones Industrial Average is built the same way.
When is the Tokyo Stock Exchange open?
It trades on weekday mornings and afternoons Japan time with a midday break, and closes for Japanese public holidays. Outside those hours the level shown reflects the last traded print or the futures market, depending on the source.
