Bombardier must have read the book the way it is obliging. This one has a near perfect triangle formation for wave 4, alternating with wave 2 and extending beyond the boundaries of the channel lines as is normal. Now it crashes as it should as everybody is downgrading it. A bit odd when you think about it as this company is, without a doubt, the infrastructure company par excellence. Low margin business to be sure but trains will be needed more and more.
The triangle measures $3 to $3.5 so a reasonable target to the downside would be $2.25 , give or take a quarter. Once there it should rebound and return to the apex for a double, at least. This is not simple a double or nothing bet as the return to the apex occurs almost always so it is a high confidence situation. Good luck.
