Thanks for your reply:)
The time period is 1-year. Two time point: the beginning point of the year and the ending point of the year.
Generally I agree with you in the first two questions. Since YTM comprises capital gain rate and divident rate,2 yuan capital gain is requested for this security at the equilibrium point.
But the third question,I can't follow you very much.I think DDM Model should be applied there.Then the equilibrium price will be only 30 yuan.I am not certain weather that makes some sense,
