Edit your stocks watchlist in Notification Center on Mac
Notification Center uses the same watchlist the Stocks app uses. Any changes you make to the watchlist in one is also reflected in the other. For example, if you add a ticker symbol to the watchlist in Notification Center, the ticker symbol is also displayed in the Stocks app watchlist.
On your Mac, click the Notification Center icon in the menu bar.
Click Today, scroll down to the Stocks widget, then click the Info button (at the top right of the widget).
If you don’t see the Info button, move the pointer over the Stocks widget.
Do one of the following:
Add ticker symbols: Click the Add button , type a company name or ticker symbol in the search box, then click a symbol in the search results list to add it to your watchlist.
Reorder ticker symbols: Drag ticker symbols up or down into the order you prefer.
Remove ticker symbols: Click the Remove button to the left of the ticker symbol you want to remove.
When you finish, click Done to return to your watchlist.
