corner portfolios and leverage investor, borrow, watch, cannot

kasinkei

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

you cannot borrow if shorting is prevented and the tangency portfolio does not have enough return to cover your need.
I probably am missing this - or am not seeing it written like this.
Please confirm, somebody.
