FSPM stock enters the Market in many variations, You stand a bigger chance of having bought shares from a shorter, another shareholder, a converted debt holder than Dittman himself.
Trading stocks is a lot like buying a car , you may pay 30k new for the car and sell it later for 25k, where did the 5k go :)
Although this is different in the sense that cars seldom increase in value i was just using that as a where did the money go kinda thing. The deal is you likely can sell your holdings although at a loss most likely.
But anyway Dittman probably has sold stock, but out of 10 million shares outstanding your stock you bought could have came from any source and may have been in the open market for years already
