Today's action may not have anything to do with their business, I think it's due to the high volume a few weeks back. This is what MM's do, create a market for a big seller to sell against, short it down while doing that, cover when it gets low, let it settle for a bit, then run it back up and profit there. Thing is, you never know if they are going to keep going after that, or fall right back down. 90% of the time they fall back down, it's those 10% that are awesome. I've not found a repeatable process to find that 10%, but I'm alright at finding these before they run. This one was fun.
