Abstract
"Post-Earnings-Announcement Drift" is a market phenomenon, which refers to investors’ tendency to overreact to the earnings announcements in conducting their investment decisions. However, this effect shows up gradually over the whole period that stock of the company is being sold out following a bullet earnings surprise. Form radically different treatments from the efficient market hypothesis (EMH), where prices of stocks will be able to quickly and fully adjust to any new coming information, it takes time for the drift to reveal itself. This happens as a slow and eventual process. This research study investigates the impact of investor sentiments and post earnings announcements drift on investor trading behavior within the Pakistan stock market context. Twelve participants that comprises of institutional and individual investors, were selected using the convenience sampling methods. Semi-structured interviews were conducted to explore the fluctuations in stock prices, investment strategies, and the market conditions. NVivo software was employed to analyze the interview transcripts, revealing themes related to the fundamental analysis, dividend importance, decision-making strategies, sources of information, investor sentiments, earnings announcements, stock pricing, information leakage, and the market anomalies. The findings highlight the significance of both the rational analysis and emotional responses in investment decisions, the importance of timely earnings disclosures, and the presence of market anomalies and the information leakage.
