The scatter plots below depict the relation between excess returns of two stocks and the market excess return. In each graph,  the market excess return is on the x-axis and the stock excess return is on the y-axis. The dashed line is estimated using a single-variable linear regression and represents the best linear fit:  Which stock has higher R²?
