Abstract

This study investigates the momentum phenomena of stocks listed on the taiwan stock exchange. The purpose of this study is to examine the differences in momentum phenomena among firm size, foreign investor ownership, individual investor ownership, and institutional investor ownership. The empirical results of the momentum phenomenon in the Taiwanese stock market are as follows. First, there is no momentum phenomenon during the whole sample period. Second, momentum profitability does not exist even if this study divides by firm size. However, the results are different if this study divides it by the investor ownership. Third, there is a significant positive momentum for firms with high individual ownership. Fourth, on the contrary, positive momentum was observed in firms with low institutional ownership. Finally, there was no momentum phenomenon when dividing by foreign ownership. This study has academic contribution in analyzing the momentum phenomenon in Taiwanese stock market considering the investor's ownership.

본 연구는 대만증권거래소에 상장된 종목을 대상으로 하여 모멘텀 현상이 어떠한 경우에 나타나는지를 분석한다. 특히, 기업 규모, 외국인 투자자 지분율, 개인 투자자 지분율, 기관 투자자 지분율에 따른 모멘텀 현상의 차이에 대해 살펴보는 것이 본 연구의 목적이다. 대만 주식시장에서 모멘텀 현상을 실증 분석한 결과는 다음과 같다. 첫째, 전체 표본 기간 동안 모멘텀 현상이 존재하지 않는 것으로 나타났다. 둘째, 기업 규모별로 나누어도 모멘텀 전략의 수익성이 존재하지 않는 것으로 드러났다. 그러나 지분율에 따라 세부적으로 나누면 결과는 달라진다. 셋째, 개인 투자자 지분율이 높은 기업에는 유의적인 양(+)의 모멘텀이 존재하는 것으로 드러났다. 따라서 기관 투자자 지분율이 낮은 기업에서는 양(+)의 모멘텀을 관찰할 수 있다. 마지막으로, 외국인 지분율에 따라 나눌 경우 모멘텀 현상이 나타나지 않았다. 본 연구는 기존 연구들과 달리 대만 주식시장에서 외국인 투자자의 지분율뿐만 아니라 개인 투자자 및 기관 투자자 지분율과 모멘텀 현상 간의 관계에 대해 추가적인 실증분석을 실행하였다는 점에 있어서 학술적 공헌을 가진다.
