the objective of asset allocation is to find an investment portfolio so that the investors degree of happiness is greatest.

Certainty Equivalent := The certainty equivalent represents the amount of guaranteed money an investor would accept now instead of taking a risk of getting more money at a future date.

Risk-Premium:=

Markowitz Allocation:

  1. INPUT: Markowitz assumes the investor has precise estimates for:

    1. $\mu$ (column vector of returns for all investable assets)

    2. $\Sigma$ (covariance matrix of all investable assets)

    3. $\sigma_{n,m}$ (the n/m entry of Sigma)

    4. $\rho_{n,m}$ (the correlation of n/m assets return)

    5. $\sigma_p^2$ (variance of a portfolio p)

    6. $r_f$ (risk-free rate)

    7. $U$ (investors utility function/measurement of happiness)

    8. $\gamma$ (investorĀ“s degree of risk aversion)

    9. $W$ (investorĀ“s wealth)

  2. ACTIVE DECISION MAKING:

  3. $w_p$ (column-vector of portfolio weights)

  4. $\mu_p$ (expected return of portfolio w_p)

  5. $\sigma_p^2$ (return variance of portfolio w_p)

  6. CHARACTERIZING RETURN DENSITY OF OPTIMAL PORTFOLIO

  7. $w_f$ (column-vector for the portfolio on the Efficient Frontier)

  8. $\mu_f$ (scalar, stands for the expected return of an efficient Portfolio)

  9. $\sigma_f^2$ (scalar, return variance of efficient Portfolio)

  10. $w_{TP}$ (column-vector with the weights of the Tangency Portfolio)
