Minimum-variance portfolio

The portfolio of risky assets with lowest variance.

Minimum-Variance Portfolio

A portfolio of individually risky assets that, when taken together, result in the lowest possible risk level for the rate of expected return. Such a portfolio hedges each investment with an offsetting investment; the individual investor's choice on how much to offset investments depends on the level of risk and expected return he/she is willing to accept. The investments in a minimum variance portfolio are individually riskier than the portfolio as a whole. The name of the term comes from how it is mathematically expressed in Markowitz Portfolio Theory, in which volatility is used as a replacement for risk, and in which less variance in volatility correlates to less risk in an investment.

However, the discrete-time model is more in line with actual investment of financial markets, and the realization of continuous time model usually requires discrete means, so this paper studies the minimum variance portfolio selection when there's the liquid asset in the discrete-time financial market.
Part of the structures of this paper is as follows: Section 2 gives the model design, constructing the minimum variance portfolio selection model; Section 3 uses Lagrange multipliers and dynamic programming principle to obtain the minimum variance and optimal investment strategy; Section 4 is to analyze the investment value; Section 5 gives the relevant numerical analysis; and Section 6 concludes the paper.
