Because you can keep adding variables even though the relationship is spurious. It all comes down to the relationship of the performance of the S&P to the growth of a tree theory. If you have a fundamental factor model that tries to predict the return of the S&P and you add a coefficient related to the growth of a tree, R^2 will increase.
