HRC did not make a killing in the Cattle Futures Market. The trades were allocated to her by her commodities advisor who was legal counsel for Tyson Foods. I know the commodity futures business- I made a living at it.
It looks to me that the trades were given to her as a bribe.In the late 1970s some commodity futures merchants were not sticklers for time stamping the trades-try that nowadays and you might be in trouble for money laundering.The clearing firm, REFCO, was notorious for sloppy record keeping and was, in fact,fined for that.
Victor Niederhoffer had an article on the subject in the Feb.20,1995 National Review which explained things very clearly. As you can guess the MSM were not very curious. A real surprise that,eh?
