Banks have to be careful about security. Not so much for your sake, but their own. That's why you won't see a lot of other domains, ads or popups on their sites.
Google will be doing all sorts of stuff without you knowing it. They have their grubby noses in almost every website you care to mention.
I just checked VectorVest, and they share your data with not just Google, but HC, the Market Herald, roymorgan and lots of others without you knowing.
Become familiar with b.locking website domains and elements. No point getting angry with HC - they're not going to reduce their ad revenue to please you.
