Every day I come across investors who think that regression to the mean has nothing to do with correlation, who don't bother to think about odds, and who take wild stabs at position sizing.

Although MLR is similar to linear regression, the interpretation of MLR correlation coefficients is confounded by the way in which the predictor variables relate to one another. Figure 1 ...
