bbdbinvestor145, 

You said  "But since July 2018 till now they've been shorting the cr##p out of it."

Respectfully, this is not correct.  Below, you'll see the short positions back to 2013.  The easiest way to look at this is in the LAST column, which is % of float.  in 2013-2017, you'll see percentages ranging from 2.xx% up to over 5.xx%

Now take a look at 2018.  It is CONSISTENTLY in the 1.xx% range, and the vast majority below 1.5% . Even more interesting, is that the two LOWEST percentages for short positions were actually when the stock was trading at its highs in July, that being specifically 1.00% and 0.84%

In summary, the "shorts" generally don't think Bombardier is a good short, and this year especially so...present share price stupidity aside. Yes, it "would have been" a good short, given the "miss".  Were the shorts there to take advantage of it?  By the numbers, I would say no."
