okeah, i wouldn't say that smart money has left the building, usually with lower volume days, it's makes it harder for MM's to create and carry on their short positions.
IMO, MM's are short, very short here.
Are they in a rush to cover ? Not until we see a blockbuster pr.
Their best option is to bring it down on low volume, shake the trees for the weak hands.
I take the low volume as a sign that the sellers have dried up.
