Much would have to change for any Company to be willing to accept much PTSC stock. So to be buying back at this time with the assumption that a Company will accept stock is insane, imo.
There are only two reasons that would make sense to buying back now. One being you know patents will be revalidated and the other is that "valuation" of the company with regard to Merger has already been determined and we are now UNDER that valuation.
Please lets not talk of BOD's belief that we are undervalued or that we can now average down our previous purchases. They've been nothing but wrong so far. This is NOT what Growth companies do.
