Two stocks moving in OPPOSITE directions actually reduce each other's risk — like two kids on a seesaw balancing each other out. This is diversification in math form. The covariance matrix is just a scorecard that tracks how every pair of assets moves relative to each other, so we can calculate the true risk of holding them together.
