Problem 44421. Portfolio diversification: choose your stocks !

Solve Later

we have the returns of 3 stocks for the last 4 years and we have to combine only 2 stocks that are less correlated. Example:

stock1=[0.1 0.3 0.22 -.15 ] ;
stock2=[0.3 0.4 -0.13 -0.22 ];
stock3=[0.6 -0.3 0.44 0.05];
So portfolio ={'stock2' 'stock3'} because they are less correlated than any other combination.

It would be wise to add additional test cases.
It would be helpful to provide an example in the problem statement.
The problem statement should not commence with a space.
