本論文採用Fama and French[1993]所提出之三因子模式為基礎，以公司規模[firm size]、帳面淨值市價比[book to market ratio]、及市場超額報酬[market excess return]為三因子，配合動能因子[momentum]及三種不同的流動性指標[成交量，成交值，成交量週轉率]來延伸探討五因子的時間序列資產定價模式。
本文的研究資料為西元1992年1月到西元2000年12月間的452家上市公司週資料，期望能解釋月資料所無法包含的資訊內涵。
結論：
(1.)台灣股票市場確實有規模效果，淨值市價比效果，動能效果，及流動性效果。
(2.)市場因子具有解釋能力。
(3.)小公司投資組合解釋效果不佳，在台灣股票市場可能有其他因素未放入評價模式中驗證。
(4.)流動性指標在台灣股票市場上，確實和股票報酬有負向的關係存在，且建議以成交量週轉率作為流動性的代表指標。
(5.)台灣股票市場有顯著的動能存在，投資者可藉由動能策略獲得更高的超額報酬。 / This article provides evidence that stock returns listed in the Taiwan Stock Exchange do have shared variation due to the “market anomalies”, such as size, book-to-market ratio, momentum, and liquidity, which have been argued by scholars and investment professionals for many years. The evidence shows that small-cap effect plays an important role in explaining the violation in stock returns after controlling for other determinants of stock returns. Besides, value, momentum, and liquidity effect do exist in the Taiwan stock market. Moreover, we suggest that turnover rate is a better proxy for liquidity in terms of its stronger relations with the stylized portfolio returns. We empirically estimate the intercepts of our asset-market models using weekly time-series data for individual securities over the sample period from 1992 to 2000 and across 452 securities. To emphasize particularly, our result does not imply that the Taiwan stock market is not an efficient market.
