A: the CV reflects the effects of both RISK & RETURN - ANSWER Q: Why's the

"optimal" portfolio?
A: add additional securities to our portfolio that will move us further in a NORTHWEST

Efficient frontier - ANSWER --the limit of how far we can move in a northwest direction
--represents all risk-return combo's that can be created by combining RISKY assets
Southeast - ANSWER Where are individual stocks plotted with respect to the efficient
frontier?
Diversification - ANSWER __________ allows us to create risk-return combo's that are
superior to a single stock
return for a given level of risk
(risk for a given level of return) - ANSWER the efficient frontier is superior because it
represents portfolios that provide the greatest ___________ for a given level of
__________ (or the least amount of __________ for a given level of _________).
efficient - ANSWER Portfolios that provide the greatest return for a given level of risk
are said to be ___________
new efficient frontier - ANSWER the capital market line (CML) is also known as
_______
market portfolio (M) - ANSWER the tangency point on the CML that indicates the
portfolio of risky assets that's best to combine with the risk-free asset is known as ____
market portfolio (M) - ANSWER on the CML, the ___________ is the optimal portfolio of
risky assets for all investors
risk-free (F) & risky (M) - ANSWER on the CML: since all investors differ in their

, more
less - ANSWER As an investor's risk aversion increases, he will allocate _______ to F
and _________ to M
Borrowing @ the risk-free rate and investing his original funds and the borrowed funds

equal to the risk-free rate - ANSWER What's the expected return of a stock with a Beta
of 0?
equal to the Market Portfolio - ANSWER What's the E(R) for a security with a Beta of 1?
Security Market Line (SML) - ANSWER The _________ is a graphical representation of
the CAPM equation that represents the E(R) for a level of Beta.
