摘要


隨著台灣資本市場的熱絡,股票市場的選股策略也日漸受到學者及市場投資人的重視。股票市場上出現多樣性的投資風格,充斥著許多不同的選股策略,而散戶投資人期望能以穩健的方式承受較低的風險以獲取較高的報酬。本研究希冀提供投資人不同的投資選擇,使投資人能在股票市場中穩健的獲利。 投資人欲從股票市場中獲取超額利潤,須辨別景氣與股票市場的變動,以利提升投資組合之績效,而股票市場循環有別於總體經濟的景氣循環,本研究採用修正B-B方法,偵測股票市場循環的轉折點,劃分股票市場的多頭及空頭,便於探討產業類股在股票市場循環週期下之報酬表現,且以夏普指數(Sharpe Index)為風險評估指標檢測類股的績效是否能優於加權股價指數的表現。另一方面,檢視金融海嘯期間與金融海嘯後投資績效之差異。 實證結果顯示投資組合持有以每季及每半年較佳,其中選出十檔類股之績效,不僅優於加權股價指數且可獲取超額報酬,以食品工業、橡膠類、汽車工業於所有時期表現最佳;多頭時期不僅每月或每季持有皆能獲利,且空頭時期部分類股有抗跌的效果。最後,建議散戶投資人,春節期間、七月及十二月為進場時機。

With Taiwan’s capital market booming, the various strategies of picking stock are proposed. Individual investors would expect to endure the lower risk and obtain the higher returns. In the present study, we attempt to provide individual investors with various investment options as creating a portfolio. In order to improve the operational performance of the portfolio, they should identify the change in macroeconomic boom and in stock market. The cycle at the stock market is different from the economic cycle, so this study employs the adjusted B-B algorithm to detect the turning-point under the bull and bear market. Furthermore, we examine the performance of the industrial sector in the stock market cycles, and adopt the Sharpe Index to detect whether the individual industrial stocks are superior to the weighted price index of the Taiwan Stock Exchange(TAIEX) .On the other hand, we also investigate whether investing performance are different during the period of the financial tsunami and after the period of the financial tsunami. Empirical results show that the performance of investment portfolio with holding a quarter and half a year is better. The investing performance of ten individual industrial stocks is not only superior to the weighted price index of the Taiwan Stock Exchange, the investors could also get the excess returns. The investing performances of food, rubber, automotive industries are the best at all periods. The monthly and quarterly excess returns exist during the bull periods and the resilience effect exists during the bear periods. Finally, the individual investors might obtain the excess returns during the New Year holidays, July and December.
