The new format is lacking critically needed information.
The layout is awful requiring much more scrolling and hunting. This is basic information that's present on your main competition of Google Finance. The main thing Yahoo got better than Google Finance was the collection and layout of news stories. This new layout ruins that one key difference and literally removes any reason for me to stay using the site. The ad placement and promoted stories really just inject too much of a 'sales pitch' onto the site, and should really be adjusted. Bottom line is that the new layout is extremely bad and should be scrapped as a whole. I can assure you I will stay with Yahoo finance for only as long as I can continue finding ways around being forced into the new format. (https://ca.finance.yahoo.com/)
Otherwise I will leave wholesale and just get used to Google Finance news feed. Also - as a side note - I've always been cool with change... this isn't a who moved my cheese situation... Some people really hate any changes; but that doesn't mean all change is good either.
Please do not be the Yahoo Employee who ignores this overwhelming feedback and forces this issue. If you're looking for a way to increase ad revenue or leverage the YF strengths, don't undermine the best aspects of it to monetize the cannibalized remains. It will not be worth it.
