既往研究指出,由於各公司特性(characteristic)不同,其股票報酬受到投資人情緒的影響程度會有差異。本文探討台灣證劵市場的投資人情緒,採用馬可夫狀態轉換模式(Markov Switching Model),重新檢視傳統評價股票模式是否可區分為不同狀態,據以判斷投資人情緒存在的可能性及其影響。結果顯示有一半的樣本,確實存在有兩個狀態。代表投資人評估股票價值採用的標準,隨狀態不同而產生變化。因此擬定投資決策時,應先探討目前投資人情緒的狀態,方能採用較佳的模式。本研究成果發現,由於各公司狀況不一,將投資人情緒視為各公司股票的評價因子,比將其當做系統性訂價因子的傳統假設應更為適當。
It is found that stock returns are affected by investor sentiment at diverse extent due to the characteristic of the company. This paper adopts the Markov Switching Model (MSM) to examine the Taiwan Stock Exchange Corporation (TSEC) listed companies. The results show that investors using different models to evaluate the value of the stock at different regimes. It is suggested that we should analyze the regime of investor sentiment when we make a financial decision. Investor sentiment is more appropriate to be a pricing factor of individual stock than a system pricing factor.
