Currently we are able to choose 2 or more portfolios, and determine the aggregate of the portfolios. It would also be nice to have a correlation function, where we can determine the correlation between 2 or more ports, based on the performance charts. This might be even more beneficial for sims. If a person is wanting to choose a group of 2 or more sims to use for his overall portfolio, he can use this to make sure they don't all zig and zag at the same time. This would be a way to minimize overall drawdowns.
