中文摘要
本研究以事件研究法探討台灣上市公司於2014年至2016年在IFRSs會計準則規範下的月合併營收資訊內涵、投資人情緒與股價累積報酬的相關性。研究發現月營收年增率對股價累積報酬具有顯著的影響,且月營收年增率變動幅度與股價累積報酬呈現正相關;而投資者情緒指標中三大法人買賣超受到月營收年增率變動的影響較低,但信用交易買賣超、當沖比率、券資餘額比及市場週轉率與月營收年增率變動具有顯著相關性。
在月營收資訊公告日前買進的個股其股價報酬的反應會受到月營收年增率成長或衰退幅度較大者的影響;而在月營收資訊公告日後累積報酬的波動度亦受到持股期間月營收年增率變動幅度影響,月營收年增率變動幅度愈大者持股期間的累積報酬波動則愈小。
產業影響部分,電子產業的月營收資訊內涵對股價累積報酬的影響大於傳統產業;在傳統產業下自營商買賣超與未預期營收具高度相關性,餘信用交易買賣超、當沖比率、券資餘額比及市場週轉率等情緒指標則與電子產業及整體市場相同。
Abstract
Based on event study, this research examines the correlation among the information contents of monthly consolidated sales, the investor sentiment, and the cumulative stock returns of Taiwanese public companies between 2014 and 2016 under International Financial Reporting Standards (IFRSs). This research found that the year-on-year (YOY) percentage of monthly sales exerts significant influence on cumulative stock returns, and the fluctuation in the YOY percentage of monthly sales has a positive correlation with cumulative stock returns. The net buying/selling of major three institutional investors in the investor sentiment index have lower correlation with the fluctuation in the YOY percentage of monthly sales. However, the buying/selling of Margin Trading, Day Trading ratio, Stock Loan and Margin Loan ratio, and Market Turnover ratio all have a significant correlation with the fluctuation in the YOY percentage of monthly sales.
The reaction of stock value caused by stock purchase before a monthly sales announcement will be influenced by the increase or decrease, whichever is larger, in the YOY percentage of monthly sales. The volatility of the cumulative stock returns after a monthly sales announcement will be influenced by the fluctuation in the YOY percentage of monthly sales during the stock holding period – the larger the fluctuation in the YOY percentage of monthly sales is, the smaller the volatility of the cumulative stock returns during the stock holding period.
With regard to the influence on industries, the information contents of electronics industries' monthly sales have a greater influence on cumulative stock returns than the same type of information contents of traditional industries do. The net buying/selling of dealers and the unexpected sales show a highly positive correlation for traditional industries. However, these net buying/selling of Margin Trading, Day-Trading ratio, Stock Loan and Margin Loan ratio and Market Turnover ratio movements follow the electronics industries and the whole market's movements.
