1. Combine a bunch of stocks on a single chart so you can identify which ones are performing best over different periods.
2. Share this list of charts with friends, family, and followers.
I just like creating and saving the overall chart to give people a better visual idea of what you are sharing with them, but you can share your watchlists very simply and easily without having to create the chart.
Note: The watchlist WILL automatically update if you add or remove a stock.
