本研究探討投資人情緒如何影響公司月盈餘之揭露，以及如何影響公司揭露好消息或壞消息之月盈餘資訊。過去研究主要探討投資人情緒影響公司資本投資、股利支付、、股票分割或是公司改名等決策，或是檢驗投資人情緒是否能解釋股票報酬變動等，鮮少討論投資人情緒是否會影響自願性揭露的原因，因此本研究有別過去學者的研究，主要探討投資人情緒與我國特有月盈餘揭露間之關係，並進一步探討揭露月盈餘為好消息或壞消息之影響。實證結果顯示，投資人情緒與月盈餘揭露之間呈顯著正相關，亦即當投資人情緒愈高時，公司愈會揭露月盈餘資訊。本研究更進一步探討揭露之月盈餘資訊為好消息或是壞消息，結果顯示當投資人情緒愈高，公司愈會揭露月盈餘，且揭露好消息之月盈餘資訊。This study investigates the relation between investor sentiment and voluntarily disclose companies’ monthly earnings. While prior research suggests that investor sentiment influences various corporate financing and investment activities, limited empirical evidence exists on the influence of investor sentiment on firms’ disclosure. We extend this research by examining the relation between investor sentiment and in Taiwan voluntarily disclose companies’ monthly earnings.Using logit analysis, we find that managers’ propensity to disclose companies’ monthly earnings increases with the level of investor sentiment and in particular, the propensity to disclose more prominently monthly earnings to public. During high-sentiment periods, managers tend to disclose companies’ monthly earnings, and disclose more prominently monthly earnings. In contrast, during the low-period, managers tend not to disclose companies’ monthly earnings.
