An Evolutionary Approach in Financial Forecast (A Random thought) VEAM 2010 at Cualo Le Hong Nhat

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.

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.
