The primary source of investor interest that disrupts the financial markets is news that reflects the macroeconomy. This study intends to track changes in investors' positive and negative market attention and their effects on stock market returns by examining the print media portrayal of the China-Pakistan economic corridor (CPEC). We access the daily and weekly coverage of the CPEC by national and international newspapers from the Bloomberg database over the period from January 2015 to December 2019. Using the Harvard psychological dictionary, we categorize the news headlines into positive and negative news sentiments. We then relate the news sentiment to the stock market returns, using quintile analysis, ordinary least squares (OLS), and vector autoregressive (VAR) models. The results show that investors react quickly and significantly to positive news. They pay more for the same stock if the positive news stream increases; hence, the stock market return also increases. In contrast, investors do not react with the same passion to an increase in negative news. These findings are in line with the theoretical rationale of the disposition effect. These outcomes may be useful for active investors and practitioners to devise investment strategies in the presence of the hype surrounding the CPEC in the print media.
扰乱金融市场的投资者兴趣的主要来源是反映宏观经济的新闻。本研究旨在通过考察平面媒体对中巴经济走廊(CPEC)的描述,追踪投资者积极和消极市场关注度的变化及其对股票市场回报的影响。我们从彭博数据库获取了2015年1月至2019年12月期间国内外报纸对CPEC的每日和每周报道。利用哈佛心理词典,我们将新闻标题分为积极和消极新闻情绪类别。然后,我们使用五分位数分析、普通最小二乘法(OLS)和向量自回归(VAR)模型,将新闻情绪与股票市场回报联系起来。结果表明,投资者对积极新闻反应迅速且显著。如果积极新闻流增加,他们会为同一只股票支付更高价格;因此,股票市场回报也会增加。相比之下,投资者对负面新闻增加的反应没有那么强烈。这些发现与处置效应的理论依据一致。这些结果可能有助于活跃投资者和从业者在平面媒体围绕CPEC的炒作背景下制定投资策略。
