Abstract
Many researchers have studied to investigate causes of volatility and they have used macro economic variables. This paper defined the volatility as that of stock. Researches on the volatility of stock and corporate performances are not adequate yet. Therefore, this paper estimate the volatility and corporate performances using ROA and Tobin Q. Results show the following suggestions, first, there is negative effect on the volatility of stock when we use ROA as the corporate performances. Second, there is positive effect on the volatility of stock when we use Tobin Q as the corporate performances.
