Here is a new one and some pretty good circumstantial evidence, Trump is making false statements to manipulate markets and timing others off with insider info.
Fun article on what is going on:
"In the last 10 minutes of trading at the Chicago Mercantile Exchange on Friday, September 13, someone got very lucky. That’s when he or she, or a group of people, sold short 120,000 “S&P e-minis”—electronically traded futures contracts linked to the Standard & Poor’s 500 stock index—when the index was trading around 3010. The time was 3:50 p.m. in New York; it was nearing midnight in Tehran. A few hours later, drones
attacked a large swath of Saudi Arabia’s oil infrastructure,
choking off production in the country and sending oil prices soaring. By the time the CME next opened, for pretrading on Sunday night, the S&P index had fallen 30 points, giving that very fortunate trader, or traders, a quick $180 million profit."
Lots more examples of this type of trades and how misstatements by Trump swayed markets markets for more suspicious trades.
