| dc.description.abstract (摘要) | 過去許多研究指出，投資人的情緒對股市有著重要的影響。許多因素可以影響投資人的情緒，其中包括新聞報導、選舉事件，以及重大疾病和災難事件。對於過去的突發公共衛生事件而言，一般而言，它們對市場的影響通常是短暫的且有限的。然而，新冠疫情似乎是一個例外情況。儘管新冠疫情對股市的影響似乎讓人感覺歷史重演，但它仍具有其獨特性。因此，本研究旨在探討過去文獻中提及的情緒指標以及COVID-19期間的特殊變數對股市報酬的影響。透過分析過去的文獻和COVID-19期間的特殊變數，我們希望獲得對投資人情緒和股市報酬之間關係的更深入了解。根據我們的實證結果，得出三個主要發現。首先，我們發現過去文獻中提及的常見情緒指標在疫情警戒期間對股市報酬並沒有顯著影響。然而，加入疫情相關資訊後，我們發現新增確診數對股市報酬具有顯著影響。這表明在疫情警戒期間，疫情相關資訊成為影響股市報酬的重要因素，增加的確診數可能引發投資人對疫情擴散和其對經濟影響的擔憂，進而對股市產生影響。第二，投資人情緒在疫情警戒前後是不連續的，在不同的樣本期間模型中皆顯示，在觀察期投資人情緒指標對股市報酬具有顯著影響，但這一效果在估計期就消失了。第三，因為投資人情緒在疫情警戒前後不連續的關係，因此沒有證據證明投資人情緒在頒布警戒後對股市報酬具有放大效果。而我們推論會有這樣的結果是因為投資人具有現狀偏誤與損失趨避的行為，以及受到疫情相關新聞的影響而產生定錨效應。 | zh_TW |
| dc.description.abstract (摘要) | Many studies in the past have indicated that investor sentiment plays a significant role in the stock market. There are various factors that can influence investor sentiment, including news reports, election events, and disaster events. Regarding past sudden public health crises, their impact on the market is typically temporary and limited. However, the COVID-19 seems to be an exception to this pattern. Therefore, this study aims to investigate the influence of sentiment indicators mentioned in previous literature and specific variables during the COVID-19 period on stock market returns. Based on our empirical results, we have three main findings. Firstly, we found that the commonly mentioned sentiment indicators in previous literature did not have a significant impact on stock market returns during the alert period. However, when adding COVID-19 related information, we discovered that the number of new confirmed cases had a significant influence on stock market returns. This suggests that during the alert period, COVID-19 related information becomes an important factor affecting stock market returns. Secondly, investor sentiment exhibits a discontinuity before and after COVID-19 alert period. In various sample periods of the model, it is evident that sentiment indicators have a significant impact on stock market returns during the observation period. However, this effect diminishes during the estimation period. Thirdly, due to the discontinuity of investor sentiment, there is no evidence to suggest that investor sentiment has an amplifying effect on stock market returns during COVID-19 alert period. We think that this result is due to investors` status quo bias and loss aversion behavior, as well as the anchoring effect induced by COVID-19 related news. | en_US |
