Update : Apr. 22, 2005
Trading units are the minimum amount of each individual stock that may be traded, and are determined by each individual listed company. Currently the majority of domestic listed companies use a trading unit of 1,000 shares. Stocks' trading units are identified in newspapers' market pages.
TSE is working to encourage listed companies with high prices and large trading units to reduce the size of their trading units to allow greater access to individual investors, who are currently put off by the expense involved in buying even one unit.
