Mean–Variance Portfolio Optimization From Mathematical Derivation to Real Data Application

we develop Mean–Variance Portfolio Optimization from first principles, starting with the full mathematical formulation and deriving the optimal portfolio weights step by step. We show how the optimization problem is constructed, how the covariance matrix enters the solution through matrix inversion, and how expected returns interact with risk in determining portfolio allocation. We then apply the model using Finance Research Gate by selecting two firms, constructing the optimal portfolio between them, and comparing the portfolio’s performance to each individual asset. The results illustrate how diversification affects volatility and risk-adjusted returns.
