Yahoo's finance site is far, far ahead of any other that I've tried. I'll be sorry to see that go. When I try another site I feel like grabbing the collar of its developers and demanding to know what is wrong with them.

Example: https://finance.yahoo.com/quotes/BABA,BIIB,FB,QQQ,UPS,VHT/vi...

I.e. with one click I can get a custom snapshot of whatever basket I'm interested in, with everything there and links to drill down for more.

Agree - Also, I think every 'program some finance stuff yourself' tutorial and online course ever has been built starting with pulling data from Yahoo finance.

They have nice iOS apps for Finance and Weather.
