Recently, the Japanese stock market has been incredibly strong, so I took some time to understand the rules of the Japanese stock market. I didn't realize how different it is from the Taiwanese stock market until I looked into it. Taiwan: Calculated using "multiplication" (fixed at 10%) Japan: Calculated using "addition" (according to a specified table, adding a fixed amount) The Japanese stock exchange has a "tier table" that determines the price range of stocks, and the maximum increase or decrease for the day is limited to a "fixed amount in yen" based on that range. For example, the "step-style" price limit in the Japanese stock market: If the stock price is between 500 and 999 yen, the maximum increase or decrease is limited to 100 yen. If the stock price is between 5,000 and 6,999 yen, the maximum increase or decrease is limited to 1,000 yen. Example 1: For a mid-low priced stock, let's say there is a Japanese stock that closed at 800 yen yesterday. According to the table: 800 falls within the "500 ~ 999" range, so the maximum increase or decrease today is 100 yen. Limit up price: 800 + 100 = 900 yen Limit down price: 800 - 100 = 700 yen (If converted to a percentage, the maximum increase for this stock today actually reaches 12.5%) Example 2: For a high-priced stock, let's say another Japanese stock closed at 6,000 yen yesterday. According to the table: 6,000 falls within the "5,000 ~ 6,999" range, so the maximum increase or decrease today is 1,000 yen. Limit up price: 6,000 + 1,000 = 7,000 yen Limit down price: 6,000 - 1,000 = 5,000 yen (If converted to a percentage, the maximum increase for this stock today reaches 16.6%) ...
