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"... :-)

comment Optimization of a portfolio of stocks
I'm still wondering why people at MMA.SE don't like Finance questions... I know the question was badly formulated, but 7 downvotes without comments... a bit too much IMO... :-)

comment Optimization of a portfolio of stocks
@SjoerdC.deVries I do agree with you... no risk free rate was informed by the OP... so you cannot talk about optimization of the risk-return relationship (i.e., the Sharpe ratio). In this case, we have to talk about optimization in the sense of the minimization of the portfolio risk.

comment Optimization of a portfolio of stocks
@IstvánZachar OK, basically the OP is interested in the minimization of the portfolio variance (i.e., risk)... to do that, you have to determine the weights for every component in the portfolio, so that the portfolio variance is as low as possible...
