No one cares about that, because TWTR can absorb those shares in one day of trading lol. The real problem for shorts is the lock-up that is in affect until the month of May, and shorts will be squeezed to much higher prices before May even gets here lol.
It's called confidence in your due diligence. For example when some knucklehead lays out that tired old line of lockup expiration on Feb 15th, longs know that it's only .018 of the outstanding shares, and won't amount to squat following a revenue beat on Feb 5th.
The degree to which we allow you to believe in the power of that very minimal dilution of the float is directly proportionate to how big the pending rally is; if it favors smaller targets you won't be permitted to run with the ball, and I will stay perma-bull, on the other hand if we hit 90+ out of it then we will probably give you a great deal of room to set up the next trap. Who knows, you might even see Cowbell sporting a Bears jersey with the right circumstances ;) 90+ correcting to 75 would be one such example.
The ultimate goal is triple digits for TWTR, and everyone from longs, to shorts, to momentum traders, to sideline watchers all have a role in this. It's a beautiful thing.
