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:
INPUT: Markowitz assumes the investor has precise estimates for:
$\mu$ (column vector of returns for all investable assets)
$\Sigma$ (covariance matrix of all investable assets)
$\sigma_{n,m}$ (the n/m entry of Sigma)
$\rho_{n,m}$ (the correlation of n/m assets return)
$\sigma_p^2$ (variance of a portfolio p)
$r_f$ (risk-free rate)
$U$ (investors utility function/measurement of happiness)
$\gamma$ (investorĀ“s degree of risk aversion)
$W$ (investorĀ“s wealth)
ACTIVE DECISION MAKING:
$w_p$ (column-vector of portfolio weights)
$\mu_p$ (expected return of portfolio w_p)
$\sigma_p^2$ (return variance of portfolio w_p)
CHARACTERIZING RETURN DENSITY OF OPTIMAL PORTFOLIO
$w_f$ (column-vector for the portfolio on the Efficient Frontier)
$\mu_f$ (scalar, stands for the expected return of an efficient Portfolio)
$\sigma_f^2$ (scalar, return variance of efficient Portfolio)
$w_{TP}$ (column-vector with the weights of the Tangency Portfolio)
