hey Thanks for introducing solving optimisation problems with one of the most useful / interesting examples:- Optimisation of Portfolio using python. Its very informative. Now I am trying new optimisations with different cases. KEEP UP the good work...
I don't get it. Why is the covariance matrix used? This means the stocks are not independent from each other. They are the same industry but apart from that they should not be tied together. What am I missing? Does this portray the sentiment of the market as a whole?
