do you guys use T-bill yield or 30-yr Treasury yield or it depends?
the reason why i asked this question is that in the afternoon session of practice exam 2 in Vol 2, Q15.2, schweser uses T-bond yield while it actually provides both of these two yields. i really could not tell why schweser used t-bond instead of t-bill when calculating required rate of return for S&P? anyone has any idea?
Long term - T bonds, Short term - T-bill
