corner portfolios and leverage investor, borrow, cannot, watch

Chuckrox8

watch out for this…. if the investor cannot borrow  than you will do corner portfolios or use the CAL using risk free and tangent portfolio.  If borrwoing  is allowed then use the CAL- borrowing the risk free and leveraging the tangent portfolio.
just sayin

if the expected return is less than the tangency portfolio, then u can combine rfr with tangency portfolio even if borrowing is not allowed
