RE:sp drop
It's the market makers keeping it down. All the tax-loss sellers can't get back in for 30 days (I believe) in order to claim a loss for 2017 if they sold near year end. They will try to keep it down until their clients can get back in on the cheap and have another run up. Give it another 2 weeks or so (at the most) and I believe we'll be going in the right direction.
