Keep in mind that the company has already mentioned this acquisition. There is a definite possibility the news of it's completion will not cause the PPS to rise much. It would certainly be nice if it does, but I have seen more than a fair share of penny stocks release news on the completion of an LOI and without much of an effect on the share price. I suppose it will depend on how many new eyes see the news.
Either way, I don't concern myself with the day-to-day trading on this one. I am confident this will pay off nicely in the coming months.
