致精进的你:
The efficient frontier：minimum risk of all portfolio with the same expected return.Maximum expected return for all portfolio with the same risk.When allowing for short sales ,the efficient frontier expands up and to the right.By adding the risk-free asset to the investment mix,the shape of the efficient frontier changes from a curve to a line,efficient frontier becomes the capital market line(CML).
The real talent is resolute aspirations.
真正的才智是刚毅的志向。
