quantifies the relationship between different risky asset classes using asset class average mean return, risk, and correlations between each set of asset class
What is a risky asset re: Modern Portfolio Theory
an investment whose returns vary - vs a non-risky asset like a T-bill whose returns are fixed
Modern Portfolio Theory uses standard deviation or beta?
Standard Deviation
Driving assumptions of Modern Portfolio Theory
-investors are rational/risk averse
-demand to be compensated for risk
-will combine asset classes which collectively will produce the highest possible average return per unit of risk
Efficient Frontier Portfolio produces what
highest possible return for unit of risk
Efficient frontier portfolios represent
mean-variance optimized efficient portfolios
Combining asset classes together can produce what re: risk
can produce a lower risk portfolio than either class individually
A portfolio below the efficient frontier offers what
inefficient - offers a lower return for the level of risk
Can you obtain a portfolio above the efficient frontier?
no
Can an individual investor have more than one efficient portfolio
No
Capital market line assumes investors invest in what

Capital Market Line Optimal Portfolio is called
Market portfolio -
How can you change your risk/return using Capital Market Line
change the ratio of market portfolio and non-risky assets
Capital market line uses beta or standard deviation
standard deviation
Capital Market Line invented by whom
