MSCI台灣指數成分股調整,對股票報酬率之影響 / The effect on stock returns of inclusion in or exclusion from the MSCI Taiwan index

許璋慶, Hsu, Nancy Chang Ching Unknown Date (has links)
MSCI台灣指數成分股的變動,於宣告日及生效日,對於新增股及剔除股的股價的異常報酬的效果;並同時以對照組比較其異常報酬。再者,依成分股加入台灣指數的幾個不同變數:加入台灣指數比重、依自由浮動(free float)調整後的股本,以自由浮動(free float)調整後的權益市值,以及外資持股比率和外資持股比率變動,比較其異常報酬的影響。 依實證結果發現,MSCI成分股的新增股及剔除股,於宣告日和生效日,皆存在明顯異常報酬。相對於對照組,於宣告日和生效日,異常報酬皆不明顯。而以加入台灣指數的比重、依自由浮動調整的股本、依自由浮動調整的權益市值,對異常報酬的影響,於宣告日及收盤後生效日,以及對新增股及剔除股的效果皆不盡相同。新增股於生效日,外資持股率小,異常報酬大;而剔除股於宣告日及生效日,外資持股率大,異常報酬大。由宣告日至生效日當天,新增股的外資持股變動較大,平均累積異常報酬亦較大;剔除股的外資持股減碼較多,平均累積異常報酬亦較大。
