danlan This is the Capital Market Line
broadex Dont understand the slope of this new line. If all securities are risk free surely all the returns are at the same level and there wont be any line??? Can some genie explain this to me.
Jdadd21 adding a risk free rate increases the slope of the line, which is more favorable to investors as it implies a higher expected return (y axis) for the same, or less, standard deviation (x axis).
