Futures are easy to make money on..... If you have inside information. Used to be a commodity trader. It is an ugly dirty biz. SHillary would have fit right in.
...or a crooked broker who is willing to allocate trades. Blair (the Tyson guy) said to the broker (one "Red" Bone), "Say, me and the little lady are going to do some trading. Put most of the winners in her account and the losers in mine."
All the broker had to do was put in trades that were matched opposites--buys and sells--and no matter which way the market moved, he'd have winners and losers. He put the winners in Hil's account until it was just over 100K. Then she closed the account. It was a transfer of money from Blair's account to hers.
Tad bit of stress in that occupation...
Everyone involved in the exchanges, in Chicago, ( it used to be a VERY SMALL community ) knew what was done ( Red Bone had done this before !)when he was handcuffed on the floor and dragged out of the building by the police. We just didn't know then, WHO he had done it for.
