Those out of sequence trades after bell have been in punch of stocks today. Check out PHOT. They have a zillion of them. Just my opinion, but I think something happened with a MM where he couldn't post the trades during the day and posted them after bell. Yes they are a lot. Other stock had so many I couldn't get back far enough to see when they started. We'll never know what really happened, but I think it was something with an MM because it happened to a bunch of stocks.
