comment Optimization of a portfolio of stocks
I was on vacations and couldn't see your answer before (nice one, btw). However, I'm still wondering why short sales have changed your efficient frontier if borrowing/lending is not allowed. I might be wrong, but as far as I remember there is no difference in the efficient frontier without borrowing/lending.

comment Optimization of a portfolio of stocks
@IstvánZachar Thanks István! My intention was actually to write my answer in an "paper"-like format... that's why I explained every line of code. But I do agree with you: sometimes I need to be more "concise"... :-)
