| Summary: | 碩士 === 國立政治大學 === 財務管理研究所 === 100 === Momentum strategies do not yield significant positive returns in the Japanese stock market in the sample period (1975 to 2009). In the three sub-periods, 1975 to 1989, 1990 to 1999 and 2000 to 2009, it demonstrates the same conclusion. Momentum effect does not exist in the Japanese stock market.
This study shows that the ranking order of winners and losers is associated with financial characteristics of firm. Overall, average trading volume and average market value of losers stocks are both smaller than those of winners stocks. In addition, the monthly return of momentum strategies has no significant seasonal pattern in the Japanese stock market.
In this study, we compare the performance of three different momentum strategies: JT’s individual stock momentum, the 52-week high and the moving average ratio in the Japanese stock market. All of three strategies in the Japanese stock market cannot receive significant profits. Final section tests the periodical analysis of momentum strategies. When extending the holding period, we can find that Japanese stock market experiences price reversal from the 11th to 18th months.
According to the historical return in formation period, we choose six-month accumulated historical return (17 to 12 months prior to portfolio formation) as the stock selection principle. Under this contrarian strategy, we find that the Japanese stock market has phenomenon of price reversal.
