How to read the data
| Item | Details |
|---|---|
| How the change is calculated | Closing price ÷ previous close − 1, shown as a percentage. On days with a stock split or reverse split, the figure may differ from what brokers show. |
| Stocks covered | About 3,650 stocks listed on the Tokyo Stock Exchange, excluding TOKYO PRO Market. Besides domestic stocks on the Prime, Standard and Growth markets, foreign stocks and the Bank of Japan's subscription certificates are included. TOKYO PRO Market is left out because trades are rare and a single trade can swing the rate sharply. ETFs, ETNs and REITs are not included. Stocks listed only on the Nagoya, Sapporo or Fukuoka exchanges are also outside the scope. |
| Update timing | The table is built automatically after the close on each trading day, once closing prices for all stocks are in. Until then, the previous trading day's table stays up. |
| Trading value | Stocks are sorted by percentage change only, with no filter on trading value or volume, so a thinly traded stock can rank high on a tiny trade. The closing price and the change in yen are shown so you can tell. |
| Company links | Where an English page of our message board exists for a stock, its company name links there. |
| Disclaimer | This page is for information only and is not a recommendation to buy or sell any stock. Accuracy is not guaranteed. Please make investment decisions at your own risk. |
