Introduction

Financial information about any company is vital while appraising the value of stock prices. Investors do consider this public financial information to assess the potential future perspective of any firm. Earnings represent the measure of firm’s profits or loss from business activities and events during a stipulated period. Dividend and earnings announcements are the two most important financial information used by the investors for decisions regarding buying and selling of any firm’s share (Lonie and Abeyratna, 1996). A firm’s return represents the capital market’s measure of performance of the firm over a period. The information of earnings announcements is used by capital market as a yardstick to assess the profitability and financial strength of any firm. New financial information is normally unpredictable by definition; otherwise, it would have been reflected in the share price far before the announcement. Earnings based on current period for any firm reflects two sorts of information: current period wealth created for equity shareholders and about possible future earnings which will be ultimately distributed to the shareholders. Beaver (1968) described the following three links between earnings announcements and share prices: (1) earnings of current period provide information to predict earnings of future period; (2) earnings of current period provide information for expected dividends of future periods; and (3) earnings of current period provide information to determine the present value of expected future dividends.
