Explanation : The capital market line, CML, is a special case of the capital allocation line,
CAL, which includes possible combinations of a risk-free asset and the
market portfolio.
Explanation : Since the XYZ portfolio return is less than the market return, this implies
that XYZ is a combination of the risk-free asset and the market portfolio.
Owning the risk-free asset is essentially lending to the government. Thus,
XYZ is a lending portfolio.
Explanation : The CML assumes that all investors have the same expectations for
securities that result in an optimal risky portfolio i.e. the market portfolio.
Explanation : Investors with homogenous expectations are rational and use the same
probability distributions, same inputs for cash flows, and thus arrive at
same valuations. Thus they will generate same optimal risky portfolio, i.e.
the market portfolio.
