Same story, John Fulton called my work number insisting that I call him back. No purpose was stated for the call. Needless to say, I find this practice abhorrent.
I also got it. Something like that "Cassimer Capital". I decided to call back and they were very aggressive trying to get info. They sell stocks. I think it is a "pump and dump" operation, getting people to buy a particular stock for a while and then they short it before dumping, making millions.
I've gotten numerous calls from these guys. Here is their website: www.casimircapital.com. Very aggressive and demand information. When they ask how much money you make, just say, "you tell me first." :)
