新產品預告效應與市場異常報酬反應 比較分析-基於iPhone的實證研究

為了解決pharmaceutical scien的問題，作者賴福明 這樣論述：

本文採用Apple多年來推出的新款iPhone產品的發布日期，並將其作為HTC、LG、三星、Nokia、Sony、Motorola等新款旗艦手機作為參考點進行比較。以蘋果新iPhone產品的年度推出日期為基準，對2007年至2018年iPhone推出之前和之後推出的各品牌廠商的手機產品進行異常報酬差異性分析。調查結果說明本研究認為非Apple製造商應在推出新款iPhone之前推出新產品。由於每年推出新款iPhone的時間接近第三季度，先前的研究顯示出蘋果品牌忠誠度最高，消費者購買其他品牌手機的意願將會下降。結果可見，在第一周銷售新手機之前存在顯著的正向異常報酬，但在銷售日之後，它們變成負異常

報酬。此外，宣佈在iPhone發布後推出的新手機則有顯著的負向異常報酬。本研究結果顯示，當新的iPhone產品進入市場時，市場對各品牌廠商的股價反應，以便為不同維度的投資者提供參考。
