| Summary: | 碩士 === 國立政治大學 === 會計研究所 === 99 === This study investigates the value relevance of unrealized gains and losses on available-for-sale securities(hereinafter “UAFS”) by adopting the framework of Sloan(1996) and using Mishkin Test(1983) to examine the market efficiency. The reults are as follows: The earnings forecasting model shows that financial holding companies’ UAFS is predictive of one-year-ahead earnings. It seems that the change of UAFS of financial holdings consists with the theory of disposition effect of Shefrin and Statman(1985) which suggests that investors tend to realize the gains of securities in the next period while hold loss securities. Therefore, it is likely that UFAS could forecast next period earnings of financial holding companies. The rational pricing model shows that only UAFS of financial holdings are rationally priced with marginal significance through abnormal returns (CAR and BHAR) for the period beginning five months after the firm’s fiscal year-end through the fifth month after the next fiscal year-end, whereas the coefficients of banks or all sample are insignificant. Combinig with the two models to test market efficiency, this study finds that unrealized gains and losses on available-for-sale securities are inefficient while the valuation gains and losses on financial instruments are efficient.
