So I've been trying to figure out how to display the minimum variance of a portfolio, but I don't know how to graph it using Solver (or any Excel tool).
I already added Solver and I have calculated the mean and standard deviation of the minimum variance portfolio in the end, but I also want to have a nice graphical display.
Also, how can one draw a tangent line from the risk free-rate (let's say 6%) to the opportunity set?
* The "s" abbreviation stands for standard deviation, I need to fix it.
Thanks a lot to anyone who is willing to share some advise.
