This study examines the effects of accounting conservatism on equity mispricing. We adopt Basu’s and Khan and Watt’s C_Score models to measure accounting conservatism and use EBO and RKRV valuation models to calculate a stock’s intrinsic value. Additionally, we consider the effects of the corporate life cycle on the above relationship. The findings show that investors would make more positive valuations if a company has a high accounting conservatism in the previous period. Second, accounting conservatism has a deferred and positive effect on equity valuation. Third, the equity value of a company at the growth stage tends to be overvalued, while that of a company in maturity stage is likely to be undervalued. Finally, accounting quality impacts equity valuations, . the better, then the less undervalued it is. Overall, we provide the evidences that accounting conservatism does matter to equity valuation, especially with the change of corporate life cycle. | The effect of accounting conservatism on equity valuation: Evidence from corporate life cycle
