"National Securities" stock brokerage cold call from "John Fulton". Sounds very much like the John Fulton who has been previously reported on this website calling from Casimir Capital 212-798-1365.
Perhaps he has moved to a new NYC stock brokerage and taken his calling list with him. Same story line and same approach as calls I have received from other Casimir brokers in the past.
This guy will call at the same time every day for weeks at a time. Sometimes leaves messages like "This is John Fulton from National, please call me back at..." with no information regarding the subject of the call. Same guy also called me from Casimir.
