Based on the current short position and the 10 day average volume, shorts can cover their position in 10 days. They have 2 1/2 trading days to do this in if they don't want to pay the dividend. Set your sell prices high if you plan on selling your shares in the next 2 1/2 days.
Add to that comment, market volume next week is going to be very weak Mon and Tue. It will be very interesting. I have 2,300 for sale at $18 if anyone wants them today. If not, lets re-think this Mon or Tues.
Shorts don't pay dividends, as the stock will adjust for the dividend, down equally amount. Only thing shorts have to fear is the PPS running up on them, not the threat of "having to pay the dividend".
If your short XYZ stock at $28.00 and on EX the dividend pays $1.00. On EX your STILL short at
$28.00, on EX the stock adjusts for the dividend to $27.00. Did you lose money? NO, It's a wash!!!
Now if 1 second after opening the PPS jumps to $28.00 or whatever, your going to be out the difference from the adjusted $27.00, unless of course you hit the open. Short calls, same thing. So being short into EX is not something to fear or even force to you cover.
