Today's price drop was probably caused by some private shareholders selling their shares to punish Twitter for the dick move of banning Trump, combined the increased market risk of having offended 25-50% of the US population.
Maybe also that Trump's tweets were a significant driver of their traffic, and therefore revenue. Twitter without Trump may in fact be a less valuable company.
this is what i thought. His followers will follow him wherever he goes. Probably his own branded services if he's smart (and not in jail etc)
You realize that selling stock in a company in no way punishes the company right? Once a company IPO's the stock price is really irrelevant to the company unless they want to raise more capital
It punishes the decision makers at the company, all of whom hold concentrated positions in their company's stock.
