| 中文摘要 | 在台灣有很多上市公司與家族有關,因此,如何改善對家族企業股票市場的投資策略對投資者至關重要。本研究根據近年台塑家族企業資料,採取EGARCH模型對台塑家族股票市場收益率之波動性進行分析,探討領頭羊公司對家族企業相關公司股票的影響。實證結果顯示:比較加入領頭羊公司變數後之槓桿效應與未包含領頭羊公司之關係看來,在1%顯著水準下顯著,故加入變數後之槓桿效應對家族企業集團之金融操作確有某種程度的影響,換句話說,在投資組合中納入領頭羊公司之槓桿效應對台塑集團股票市場操作之穩定性是有助益的。本研究進一步利用Granger因果關係,選出領頭羊的個股,運用追隨領頭羊股價的程式交易,淨利增幅為20.52%,說明此一技術分析背後所代表的操作策略是有利可圖的,投資人可以運用追隨領頭羊公司的特性,增進操作家族企業股票之績效。 |
