The Classical Theory of Finance Risk and Return: A Brief Review Investors prefer high expected levels of return and dislike risk. It would be a mistake to ask the question as: Which investments are most attractive? By creating a portfolio, one can achieve the same level of return as any single asset, but with a less volatility.

The Classical Theory of Finance The One-Fund Portfolio: Illustration Mean return Standard deviation (Risk) One fund M C (CAPM): A (Single Asset) r

The Classical theory of Finance Implication of The One Fund: CAPM CAPM: Which says that the expected return of a security equals the riskless rate of interest, r, plus a risk premium, associated with the security’s beta. Rationally, If this expected return does not meet or beat the required return, then investors should not hold this asset or security.
5
The Classical theory of Finance Matching CAPM with the Real World Assumption on rational expectation. Rational behavior and adjustment mechanism. Embedded in the mechanism is EMH: prices can never be too far out of line.
