Google Finance now lives as a tab in Search, and some features are going away.

Google has announced that the Web version of Google Finance is getting a redesign. The new stock-tracking interface will primarily live in Google Search, where a new "Finance" tab should be popping up soon as a search type. The existing google.com/finance site will soon start redirecting to this interface, too.

Just like the current Google Finance, you'll get stock prices, historical graphs, and news. A few Google Finance features aren't making the cut, though, namely the portfolio features and the ability to download historical data. There is still a "my stocks" feature that lets you keep an eye on favorite stocks, but there will no longer be a page for your transaction history and current holdings

Google has been on a redesign kick lately, having launched new versions of Google News and Google Calendar in the past six months. Just like those sites, the old Finance design has been around since 2011, when Google was in its "red and gray" design phase. The new design fits in a bit better with Google's current "Material Design" style, which organizes content into rows of cards.
Google Finance has seen a lot of neglect by Google over the years. The Android app was basically designed in the Android 2.3 Gingerbread days (2010) and allowed to stagnate on the Play Store for five years before it was pulled in 2015 and never replaced. The Finance website isn't doing much better: until this redesign, it needed Adobe Flash—in 2017—to draw the interactive stock charts. Flash is blocked by default in Chrome, which meant that Google's finance site, when run on Google's browser, popped up a "please enable Adobe Flash Player" message when used.

With the new Finance redesign, it seems Google is at least slightly interested in its Finance section again. The company ends the blog post with "We hope to continue to improve this experience in the future" and a call for feedback at the "send feedback" link on the new Finance page.

That's yet another 2011-era "red and gray" design down the tubes. There aren't that many sites left inside of Google that use the old design. The big remaining one is Gmail.
