How can I add notes to my Portfolio?
On the "Summary" tab, go to the stock symbol and move the cursor next to it. You will then see an option to add a note.
This can also be done via the symbol page.
All saved notes can be accessed together, and edited, on My Notes page (https://seekingalpha.com/account/my-notes)
