The stocks that get hit on reverse splits are usually dying companies that are doing it to artificially inflate the price, this is a completely new entity that is hitting the market for the first time and the r/s is simply part of the agreed upon merger process. This is only my opinion, I can't guarantee anything, and have been wrong before, but I am not expecting a real price decline at all, more like an increase if anything.
The way I see it, near term the best opportunity with this stock will be after the merger, to before the new restricted shares eventually become part of the float. That is the best window and chance for a real price increase near term, my guess & hope anyway. No idea how long that window will be, but looking forward to Monday. Wonder if we'll be on the vaunted daily list finally?! lol
As far as best time to buy this stock, I'm pretty sure it was last year. :p
