聯一光 Listed as Disposition Stock, Matching Changed to Once Every Two Minutes
The Taipei Exchange announced on Oct 28 that 聯一光 (3441) showed abnormal trading indicators recently and will be listed as a disposition stock from Oct 29 to Nov 6, during which trading will be matched once every 2 minutes. The disposition is related to factors including its P/E ratio, price-to-book ratio, turnover rate, and the trading value share of specific brokerages, with multiple trading figures reaching relevant regulatory thresholds.
P/E Ratio of 82.10 Times, Turnover Rate Reaches 52.22%
According to the announcement, 聯一光 recorded a P/E ratio of 82.10 times on the day, with a price-to-book ratio of 9.63 times, approximately 4.37 times the price-to-book ratio of its industry category; its turnover rate reached 52.22% on the day, indicating very active trading. In addition, Yuanta Securities bought approximately NT$1.091 billion of 聯一光 on the day, accounting for 26.02% of the stock's total trading value, while its sell amount was approximately NT$1.077 billion, accounting for 25.68%. The competent authority therefore decided to impose disposition measures to cool short-term trading activity and maintain market order.
冠西電 and 東台 Listed as Watch Stocks for Two Consecutive Days
In addition to 聯一光 being formally listed as a disposition stock, 冠西電 (2466) and 東台 (4526) also showed abnormal trading signals. According to the TWSE announcement, the two stocks were listed as watch stocks on Oct 27 and 28 for two consecutive trading days and have entered the potential disposition watch list, with market attention on whether they will be further upgraded to disposition stocks. Inclusion in the potential disposition list does not mean disposal is certain, and remains subject to subsequent trading conditions and announcements by the competent authority.
Watch Stock and Disposition Stock Mechanisms, Investors Should Note Risks
The Taiwan stock market has regulatory mechanisms such as watch stocks and disposition stocks, aimed at strengthening management of sharp price fluctuations, abnormal trading volumes, or high turnover rates. Generally, when a stock's price movements or other trading indicators reach prescribed thresholds within a specific period, it may first be announced as a watch stock; if it repeatedly triggers relevant standards in subsequent periods, it may be further listed as a disposition stock. Disposition measures may include reducing matching frequency and extending trading intervals. As matching methods during the disposition period differ from normal trading, investors holding related stocks should note the implementation dates and specific measures stated in the announcements, and prudently assess trading risks.
