中文摘要 | 近年來,台灣股票市場常常存在各種股票概念族群,例如中國概念股、iPhone概念股等,此與財金學者針對公司股票的特性加以分類-在學理上我們將之稱為「風格」 (style),有異曲同工之妙;針對股票市場中特定的風格族群進行投資、以獲取超額報酬的風格投資法 (style investing),早已成為近年來許多專業投資機構投資決策的方式。本研究利用投資組合法 (portfolio approach),以明確的操作性定義,據以建立價值、成長、大型、及小型等四種風格投資組合 (style portfolio),與市場投資組合進行超額報酬之檢定。本研究之主要結果有三:第一,價值效應與成長效應不論在短期及長期皆呈現顯著,價值效應尤比成長效應顯著;而大型股效應(或反向規模效應)則存在長期中,一般小型股的異常報酬則不存於台股;第二,分析風格投資組合在多頭、盤整、及空頭市場下的短期表現,僅有價值、成長、及大型股在盤整市場為顯著,但長期報酬則都顯著,顯示風格投資法具有在長期獲得超額報酬的特別意義;第三,因價值、成長、大型股皆為建立在基本面之選股策略,顯示台股仍較偏向弱式效率市場。 |
英文摘要 | In Taiwan stock markets, various concepts of stocks have been raised by practitioners to catch the attention of investors. These so-called concepts are similar to the terminology, style, in finance research. Style investing is referred to as investing similar company characteristics as a style portfolio in order to obtain excess returns. This study examines the short-run and long-run performance of excess return among four groups of style portfolios, i.e., value, stocks, large-capitalization, and small-capitalization, with the portfolio-constructing approach. Three major findings are drawn from the study. First, the study finds evidence for the value effect, the growth effect, and the large-cap effect (or reverse size effect) in Taiwan stock market. Second, since the three market anomalies are statistically significant in the long-run, the implication is that investors should pursue the long-run performance rather than in the short-run with style investing. Third, the market anomalies indicate that Taiwan stock market is weak-form efficient. |
