NEW YORK -- It hit late Friday, but a massive trade is looking for a rally in Facebook (FB).
It has been a wild ride through two rounds of action.
The Alphabet unit can't just 'put a band aid' on advertisers' concerns, lest it risk losing its second-largest advertising growth generator.
YouTube has the resources and tools to deal with its extremist content problem. And top brands have big incentives to keep spending on it.
The list is piling up.
