Portfolio Theory Flashcards
A portfolio’s return depends on the
expected return on the assets in the portfolio and their weights in the portfolio
A portfolio’s risk depends
the risk of the assets in the portfolio, their weights in the portfolio and the relationship between the assets in the portfolio.
An asset’s risk can be measured by
its variance
the investment opportunity set
is the set of all available risk- return combinations at different weight combinations
The efficient frontier
the set of portfolios that have the highest return for a level of risk, or the lowest risk for a level of return.
what will impact a portfolios variance most?
changes in covariance, compared to change in weight or asset risk
utility functions
represent risk/return preferences. We will work with quadratic utility. this is used in the CAPM
