This paper collects data on the monthly returns of listed and over-the-counter stocks listed in the Taiwan Stock Exchange and Taipei Exchange to determine the presence of low-price stock effect on the two exchange markets during the period between January 1971 and December 2020. The low-priced stock group, regardless of using NT$5, NT$10, NT$15, or NT$20 as the cut-off point for low price, shows a significantly higher abnormal return than does the high-priced group within the first 12, 24, and 36 months of purchase. In other words, a low-price stock effect exists in Taiwan’s exchange markets. Through an examination of the low-price stock effect in the Taiwanese electronics industry and non-Taiwanese electronics industries, this study reveals the presence of a low-price stock effect in both industries, with a greater effect in the electronics industry.
