Look for the “slanted pencil” symbol on the button adjacent to the “+ Add” button. Click that button, and the portfolio should appear in a pop-up window. There will be “trash can” symbols on every portfolio holding line. Click the trash can symbol on the same line as the portfolio holding you want to delete. It should then immediately disappear from the list. Click the “Done” text in the upper right corner of the pop-up window to close the window.
