Can I switch back to the previous version of Yahoo! Finance Portfolios?
This article describes the limitation around switching back to the previous (classic/old) version of Yahoo! Finance Portfolios.
Unfortunately, It is not possible for users to switch back to the previous/old version of Yahoo! Finance Portfolios.
While we recognize that there are some differences in functionality in the new version of our Portfolios offering, every change was made with the goal to improve our Portfolios section for all users. This includes a new design and a more intuitive set-up.
We hope you'll give this new version a try.
