I'm taking an online class the teacher refuses to answer questions and makes the course work as difficult as possible (wish I would've seen her rate my professor rating before enrolling). Anyway, This is the question - Determine the return on the market, Rm, based on the weights constructed for portfolio A. Portfolio A consists of two assests, A short levered stock position at 59% and a T-bond with a par value of 15,000. I have the weights for the calculation but I need the ROPC's of the stock market. My question- Do I calculate the ROPC's for the stock market as short positions? If so is it levered to 59%? She only gives examples for stock market ROPC for a long stock position, in the example it is not levered.
