The result is use to appraise the efficiency of the Korean stock market. Findings statistically oppose S. Basu (1977) results. He realized Price-Earnings ratio effect but this study found no statistical evidence supporting the relationship between Price-Earnings ratio and return on common stock. Using Fama and Macbeth (1973) methodology of portfolio formation, the investigation could notice any statistical Price-Earnings ratio nor size effect. If a test of financial market efficiency depends on Price-Earnings ratio and size effect only, then Korean stock market is efficient, however, within this context, it is difficult to determine the extent (weak, semi strong or strong) to which the market is efficient. Further study on bid-ask spread (measure of information asymmetry) will assist to determine the level to which the Korean financial market is efficiency.
