Let's just wait and see...We don't even know if there's even going to be a reverse split as of now.
No one is going to convince anyone or have any meaningful impact on the stock here.
You might as well consider this a gamble, a lottery of opinions, for those who like to brag that 'they knew' the impact of this possible action on the sp... looks like there's plenty of times were a split worked or not... from whatever point-of-view you're standing.
I can just point that this annoucement of Bombardier looks like a kick in the hornet nest of traders, so many of them started to post like their life depended on it. A therapist would say that they look a bit rattled.
