The Central News Agency (CNA) reported on April 21st that legislators had previously proposed changing Taiwan's stock trading unit from the current 1000 shares to 1 share, to bring Taiwan's stock market closer to international standards. The Taiwan Stock Exchange stated today that such a system adjustment is a significant matter and will initially focus on optimizing odd-lot trading.
Du Huijuan, Deputy General Manager and spokesperson for the Taiwan Stock Exchange, told CNA that Taiwan's stock market's trading unit of 1000 shares per lot is indeed the largest in the world. Currently, most stock markets in Europe and the US use 1 share as the unit, and many Asian markets like Japan use 100 shares per lot. The adjustment of relevant systems is a future direction, and the Taiwan Stock Exchange is internally collecting relevant data on foreign experiences for evaluation.
However, Du Huijuan also stated that such system adjustments are a major undertaking with broad implications. For instance, investors' trading habits must change, otherwise they might place wrong orders. The number of transactions for securities firms could surge, requiring expansion of their computer information systems. Additionally, there are many low-priced stocks, the trading costs of which, along with regulatory legal frameworks, must be considered simultaneously.
Du Huijuan mentioned that the Taiwan Stock Exchange is collecting data and discussing plans, and the progress is not very fast. At this stage, optimizing odd-lot trading will be prioritized. For young investors who may have insufficient funds, odd-lot trading in Taiwan stocks is already quite active. In the future, efforts will be made to equalize the trading restrictions between odd-lot trading and regular trading.
Chen Junhong, Chairman of the Securities Dealers Association, also stated that regarding the change in Taiwan's stock trading unit from 1000 shares per lot to 1 share, the relevant supporting measures and regulations from the Taiwan Stock Exchange have not yet been released, so it is not possible to comment at this time. The Securities Dealers Association has not yet proposed or discussed this matter. (Editor: Lin Jiaxian) 1150421
