The research sample consisted of  12 companies listed on the Indonesia Stock Exchange with LQ45 Index. The research method used was panel regression with the random effect model estimation method. This study found that there was an insignificant positive relationship between ESOP and Covid Cases Growth on the volatility of the company's stock price and a significant positive relationship between Controlling Ownership and stock price volatility during that period.
