big: Seems like I recall a lot of selling around 12/2 and 12/3. I figured it was people setting up to get back in in the first few days of the new year... FWIW.
Retail investors with brokerage accounts, I agree with. MMs not about any of that. It's all about selling/shorting and making a profit out of it and only way is to sell/short and find the shares later and they all hope they never have to. They do it anyway they can as long as they can get away with it. A very timely contract award would really screw with their plans today or Monday, believe you me!
