碩士 === 國立交通大學 === 經營管理研究所 === 95 === In this study, we investigate the usefulness of past returns, trading volume and R&D expenditures in predicting cross-sectional returns for various momentum portfolios. The study is organized into three parts. In the first part, we only use one of the three factors to form portfolios. In the second part, we use two of the three factors to form portfolios. In the three parts, we use all of the three factors to form portfolios. Similar to methodology of Lee and Swaminathan (2000), we analyze the data from TSE and OTC information and electronic firms in Taiwan during the period January 1998 to September 2006. Specifically, we discuss the influence of different sequence of forming portfolios rules by three factors on future returns. Our results can be summarized as follows. First, using simple return or R&D momentum strategy can’t capture correct stocks trend. Second, using simple trading volume momentum strategy can capture the stocks which were overreaction. Third, we found MLC hypothesis also exists in Taiwan information and electronic stock market. Fourth, Similar to MLC hypothesis, the relationship of past returns and R&D expenditures also can be showed by another momentum life cycle. Fifth, the performances of investing strategies using three factors are better than using only one or two factors. However the performances are influenced by different sequence of forming portfolios rules.
