The recent literature focused on the negative relation between two measures of conservatism: asymmetric timeliness of earnings and the market to book ratio (MTB) in short periods. We expected this relation would be positive when asymmetric timeliness of earnings measured cumulatively over long horizons. The result inconsistent to our predict show negative relation between two measure of conservatism that statistically significant
