I was wondering why do they need to release any press releases? I know why we need them to announce what they have accomplished. But, is there a business reason that directly benefits the company? Say they are quietly generating revenues, right now is increasing the PPS something that needs to happen for them? Especially when they are in the process of buying back shares. Ultimately to grow the company PPS needs to increase, but doesn't it benefit them to keep things quiet for a while?
