Choose and compare individual stocks in a portfolio on different time scales with or without benchmark indices.
NOTE: This app is currently not working, as the stock data api has changed. I will try to update it at some point.
This particular portfolio tracks a bunch of interesting tech stocks, some of which I have in my own portfolio.
For details on how to make a version of this app yourself, please read my article on Towards Data Science
You can play around with the app here
