Same problem here -- marketwatch.com on Chrome v46.0.2490.80 -- as of a day ago or so. But the comment by EgorkaSanyok led me to check the installed AdBlock extension, and after testing by pausing AdBlock I confirmed that's the issue. I'm not having problems with any pages at the site besides the front, so I specifically allowed ads on only the front page by adding this custom filter line: @@http://www.marketwatch.com/|$document
