本篇論文以透過股票市場的波段行情,選定2001年10月1日至2007年10月31日為觀察期,分別在股市波段低點時,買進高淨值市價比、跌破面額股及跌破面額股當中高淨值市價比之股票,長期持有,待股市景氣循環達到高點時,賣出持股,獲取較高之報酬,並檢視其報酬率及波動性。實證結果顯示,大部分的時期買進高淨值市價比、跌破面額股及跌破面額股當中高淨值市價比之股票,可以獲取比低淨值市價比、未跌破面額股及跌破面額股當中低淨值市價比之股票,較高的報酬。在報酬波動性的檢定方面,高淨值市價比、跌破面額股票及跌破面額股票當中高淨值市價比之股票,在大部分時期亦伴隨著較高的風險。在單位風險報酬方面,若考慮風險因素,則仍以買進高淨值市價比、跌破面額股票為佳。因此買進高淨值市價比、跌破面額股及跌破面額股當中高淨值市價比之股票,不失為理想的投資標的。
This paper takes the period from October 1, 2001 to October 31, 2007 as the observation period based on the wave band condition of the stock market. The High Book-to-Market Equity, under Par Value Stocks and the stocks of High Book-to-Market Equity among the under Par Value Stocks were bought in at the low point of the stock market wave band, and were held for a long period of time. The held stocks were sold when the stock market cycle reached a peak point to gain a higher return. The rate of return and the wave property were reviewed. The empirical result showed that in most times, buying in High Book-to-Market Equity, under Par Value Stocks and the stocks of under Par Value Stocks among the under Par Value Stocks can obtain higher return than buying in Low Book-to-Market Equity, not under Par Value Stocks and the stocks of Low Book-to-Market Equity among the under Par Value Stocks. In the verification of the return wave property, the High Book-to-Market Equity, under Par Value Stocks and the stocks of High Book-to-Market Equity among the under Par Value Stocks are also coupled with higher risks in the most of time. In the unit risk premium, buying in High Book-to-Market Equity, under Par Value Stocks is still preferred upon the risk factor. Therefore, buying in High Book-to-Market Equity, under Par Value Stocks and the stocks of High Book-to-Market Equity among the under Par Value Stocks is an ideal investment target.
