Default [Q] Battery drain cause?

I think I've found a cause for battery drain on my and possibly other devices. It seems every few moments an icon flashes by very quickly. I began noticing this a month or so and upon closer inspection when I can actually get a good look at it, it looks like a grayed version of the Sense 5 Stocks app icon . It's strange because I don't use the app at all. Any idea what this actually is/could be or potentially a way to stop it. Or is nobody else experiencing this and I'm just crazy or unlucky?

Any help appreciated and I will answer any questions you need to help resolve this.
