OVERVIEW
We have expectation of extra reward for taking up more risk.
An asset risk premium is the additional compensation required above the risk-
free rate for holding that asset.
At the market level, the market-risk premium is the additional return above the
risk-free rate to hold the market portfolio for a given asset.
CAPITAL MARKET LINE
Where,
rp = expected return of portfolio
rf = risk free rate of return
rm = market rate of return
σp = standard deviation of portfolio
σm = standard deviation of market
Where,
ρim = correlation coefficient of security and the market
σi = standard deviation of security
σm = standard deviation of the market
COVim = covariance of security and the market

Editor's Notes

  • #13 Talk about efficient frontier related with risky securities only Relate with market ma there are both risky and risk free assets
  • #14 Risk free and risky securities The CML is tangent to the efficient frontier curve which gives the optimum portfolio point The formula that gives these points to plot is in next slide
  • #15 CML includes standard deviation. i.e. both systematic and unsystematic risk Defined both risks Unsystematic risk can be diversified so market only rewards the systematic risks
  • #16 Beta compares the security’s volatility with the industry
  • #18 Beta <>= 1 +1 -!
  • #21 Explain this example
  • #22 Security market line
  • #23 When we are well known about the diversification this quote of an American Investor , Warren Buffet makes a very good sense which teach us to diversify the product.
  • #24 Considers systematic risk, assumption garne ho bhane ta it will take decades to realize which one is better option but systematic risk le garera its helpful to assume certain point while unsystematic risk bhaneko bhai pari aune kura ho This concept help us to understand the possible risk according to market and it helps us assume the requires rate of return .
  • #26 CAPM can be denoted as a basic concept that if we have the higher risk then we must set certain required rate of return to put an option to choose That risky option compared to less risky and risk free option. Beta is nothing but a rate of additional volatility of investment option in this case, the beta can be called 1.1 this means 10% riskier when the slope is downward and 10% profitable when the slope is upward.
