RE:Bombardier deserved a 20% plus upswing todayI can understand why there will never be a 20% upswing day. I believe the reasoning is this: if the shorters all sat back and let the share price go where it wants to go (finding the equalibrium price between those wanting to buy and those who actually own shares wanting to sell), and it resulted in a upswing of 20% it would not only cause a problem for the shorts needing to cover, it would also attract a lot of attention. That would likely push the price up even higher and all of the FOMO's would jump on board. That would put the shorters even further under water.
So, the smart thing to do if you are short and have deep pockets is, even on a day like today with great news, short the stock as much as necessary to limit the rise to say 5% or less. That avoids the frenzy and when things calm down and eveyone thinks the stock has settled (and impatient people begin to sell), those shorters can slowly start covering.
While they would still be at a loss for shorting a rising stock, they would likely not be bankrupt can can live to cause further problems another day.
In conclusion, while I think BBD should rise significantly, I can understand why I am unlikely to see too big of a movement in any given day. I think it could take a week before we see where the price is going to settle.
