Once you have added portfolios to your Favorites list you can then access them in the Portfolio page via the Favorites button.
Clicking the Favorites button displays all the portfolios in the Favorites list. The last portfolio to be added is displayed at the end of the list.
This button is only enabled if you have already added at least one deal to your Favorites list.
For other ways of opening portfolios see Overview of Opening a Portfolio in the Portfolio Page.
