I would say that’s category page. So when a visitor clicks on that specific category, it would show that stock ticker and then content and other sidebars below just like in the photoshoped picture. But just on that category so when a visitor decides to read any of the posts, it wouldn’t flash there too. I’m keeping content only in single posts layout. 😀
For the ticker I’m using Custom Stock Ticker plugin and the width can be set if that helps.
