Portfolio Operations

Creating the Portfolio Object
To create a fully specified mean-variance portfolio optimization problem, instantiate the Portfolio object using the Portfolio function.
Common Operations on the Portfolio Object
Common operations for setting up a Portfolio object.
Setting Up an Initial or Current Portfolio
The Portfolio object property InitPort lets you identify an initial or current portfolio.
Setting Up a Tracking Portfolio
The Portfolio object property TrackingPort lets you identify a tracking portfolio.

Portfolio Optimizations

Asset Allocation Case Study
This example shows how to set up a basic asset allocation problem that uses mean-variance portfolio optimization with a Portfolio object to estimate efficient portfolios.
Portfolio Optimization Examples Using Financial Toolbox™
Follow a sequence of examples that highlight features of the Portfolio object.
Portfolio Optimization Against a Benchmark
This example demonstrates optimizing a portfolio to maximize the information ratio relative to a market benchmark.
Leverage in Portfolio Optimization with a Risk-Free Asset
This example shows how to use the setBudget function for the Portfolio class to define the limits on the sum(AssetWeight_i) in risky assets.
Portfolio Optimization with Semicontinuous and Cardinality Constraints
This example shows how to use a Portfolio object to directly handle semicontinuous and cardinality constraints.
Black-Litterman Portfolio Optimization Using Financial Toolbox™
This example shows the workflow to implement the Black-Litterman model with the Portfolio class in Financial Toolbox™.
Portfolio Optimization Using Factor Models
This example shows two approaches for using a factor model to optimize asset allocation under a mean-variance framework.
Portfolio Optimization Using Social Performance Measure
Use a Portfolio object to minimize the variance, maximize return, and maximize the average percentage of women on a company's board.
Risk Budgeting Portfolio
This example shows how to use riskBudgetingPortfolio to create a risk budgeting portfolio and portfolioRiskContribution to compute the risk contribution of the assets in the portfolio.
Backtest Using Risk-Based Equity Indexation
This example shows how to use backtesting with a risk parity or equal risk contribution strategy rebalanced approximately every month as a risk-based indexation.
Create Hierarchical Risk Parity Portfolio
This example shows how to compute a hierarchical risk parity (HRP) portfolio.
Risk Parity or Budgeting with Constraints
This example shows how to solve risk parity or budgeting problems with constraints using estimateCustomObjectivePortfolio.

Portfolio Theory

Portfolio Optimization Theory
Portfolios are points from a feasible set of assets that constitute an asset universe.
Portfolio Object
Using the Portfolio object and associated functions for portfolio optimization.
Default Portfolio Problem
The default portfolio optimization problem has a risk and return proxy associated with a given problem, and a portfolio set that specifies portfolio weights to be nonnegative and to sum to 1.
When to Use Portfolio Objects Over Optimization Toolbox
The three cases for using Portfolio, PortfolioCVaR, PortfolioMAD object are: always use, preferred use, and use Optimization Toolbox.
Role of Convexity in Portfolio Problems
Characteristics of convexity, concavity, and nonconvexity in portfolio problems.
