There was no "stomach" required. They knew what was going to happen since they're insiders.
Exactly, that is how they make their money. I'll go one step further and tell you that I think that someone like the "founder" of Amazon Jeff Bezos, GeorgeZoros, Warren Buffet, Bill Gates etc, were all picked as heads, figures by powers above them. They cooperated and have been rewarded with fame and fortune.The second they go against the powers, they are sacked, like Epstein, Bill Cosby, Kennedy's, Nixon.......
Look at Obama, how did he make millions while just earning $400,000 a year as president? Same for Peℓσѕι and the Clintons? Answer - stock market investments. Impossible to call insider trading because anyone could have done the same thing by luck. Though few ever do.
