CSE Portfolio Risk Analysis

Portfolio Risk and Return Analysis on the Colombo Stock Exchange (CSE)

This project applies modern portfolio theory to the Sri Lankan equity market, focusing on diversification and risk-adjusted performance for a small, beginner investor. Using historical data from selected CSE stocks, the analysis estimates expected returns, beta coefficients, Value at Risk (VaR), and Treynor Ratios. Three portfolio strategies — equal-weight, conservative, and aggressive — are compared to evaluate the balance between risk and reward in practical investment decision-making.
