1) I’m not sure what different metrics you though I suggested. To clarify, CAPM and Falkenstein’s model are about returns for a constant portfolio over a given period. If you want to talk about a changing portfolio, you’ll have to approximate this as several time periods each with a different constant portolio and geomtrically average the returns.
