The other day on Twitter I asked how liquid NFLX was when it crashed since I was away from the desk ... no one replied because I'm followed only by bots and fantasy footballers, so I had to look it up on my own. It fell from 448 to 336 in the first 15 minutes after the close. Must have been impossible to short it as it collapsed. The next morning it opened around $332 and rallied to $360. If trading were easy, everyone would be rich.
