# Create Portfolio

Create Portfolio object for mean-variance portfolio optimization

To create a fully specified mean-variance portfolio optimization
problem, instantiate the `Portfolio`

object using
`Portfolio`

. For
information on the workflow when using `Portfolio`

objects, see Portfolio Object Workflow. For information about creating a Portfolio object, see Creating the Portfolio Object.

### 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

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™**
