Max drawdown duration matlab12/12/2023 Leverage the backtesting framework in MATLAB to automate the execution of strategies over historical time periods, aggregate costs, and generate performance metrics like returns, risk metrics, and drawdowns that help identify the best strategy. The Portfolio object in MATLAB can be leveraged to integrate ESG criteria or add asset diversification to the portfolio optimization.ĭifferent asset allocation techniques can be evaluated by backtesting them over a historical or simulated time period with a preferred rebalancing strategy. The portfolio optimization space continues to evolve with techniques such as the machine learning–based hierarchical risk parity approach and alternate sources of data such as environmental, social, and governance (ESG) metrics that are introduced into the asset allocation process. Quantitative researchers and portfolio managers might also want to add diversification techniques, perform an optimization that minimizes tracking error, or find a portfolio that equalizes the risk contribution of the assets in the portfolio. While the focus of portfolio optimization is to find the best allocation given a set of constraints, what may be considered the best portfolio can go beyond traditional risk-return tradeoffs. MATLAB ® provides built-in frameworks to perform mean-variance, conditional value-at-risk, and mean-absolute deviation portfolio optimization. The Evolution of Asset Allocation Portfolios satisfying these criteria are efficient portfolios and the plot of the risks and returns of these portfolios form a curve called the efficient frontier. The classical approach, known as modern portfolio theory (MPT), involves categorizing the investment universe based on risk (standard deviation) and return, and then choosing the mix of investments that achieve a desired risk versus return tradeoff. The convention is to specify portfolios in terms of weights, although portfolio optimization tools also work with holdings. Overview for performance metrics supported by Financial Toolbox software. ![]() Use maximum drawdown to calculate drop from maximum to minimum return over a period of time and expected maximum drawdown of a linear Brownian motion with drift. ![]() Portfolios are points from a feasible set of assets that constitute an asset universe. Using Maximum and Expected Maximum Drawdown. Portfolio optimization is a formal mathematical approach to making investment decisions across a collection of financial instruments or assets.
