What is Portfolio Optimization?Portfolio Management and Optimal Trading strategy combines asset allocation optimization and technical analysis constant optimization to maximize returns on financial investment portfolios. Historical financial data can be based on business cash flows or financial security data downloaded automatically from the web. The portfolio optimization module provides various options for risk quantification including overall risk under the Sharpe ratio, downside or semi deviation under the Sortino ratio or analysis of gains to losses under the Omega ratio. Results of the portfolio optimization are displayed with total return comparison charts and trading required for rebalancing to the optimal portfolio weightings. The technical analysis module analyzes the value added total return from signal trading on five key technical indicators: simple moving average, rate of change, moving average convergence divergence, relative strength index and Bollinger bands. The time period constant parameters for each of the technical indicators can be automatically optimized to establish the optimal trading strategy that provides the maximum total return for the portfolio. Periodic processing of the weighting and technical analysis optimization provides a concise and automated solution for portfolio management and optimal trading strategy. The solution runs in Excel for both Macintosh and Windows operating systems.
