The market is spooked over the CFO resigning (since it really went South just before and right after this news came out     ......and hence the market seems worried that there may be something more "ominous" behind the curtains to explain his departure.    

 If indeed there is not anything else going on besides just his desire to move onto something else (due to personal reasons) then eventually this recent weakness will eventually reverse itself.   (A year from now Mr. Farrant's departure will no longer stir any fear.)    ....at least that is my take on it all, whether over simplified or not.     

I'm long and strong  ....selling your shares at these levels and in this (current) low volume arena would be akin to selling one's soul.   But with that said I accept the fact that the market does what it pleases whether rational  or not   .....only by holding this stock longterm can I "get the upper hand" on such matters and allow CSG's fundamentals and large reserves/resources (relative to market cap)  to eventually "lay the course" and play itself out in a very positive and rewarding manner  .......as opposed to this frustrating "trading activity" as of late.
