Then, after the position was stopped out, prices could rebound and go back along the direction originally wanted by the trader. But this time the trader might not have a position. Any combination of possibilities are more likely to happen with overnight positions. For all those who think Hillary Clinton had special treatment and inside information that could foretell price moves similar to insider trading that occurs illegally with stocks on Wall Street, I suggest they look again at the immensity of the generic futures markets. We are not dealing with a company stock whose price may change tomorrow due to a corporate merger or some other unexpected information only available to insiders.
Futures are different.
The generic markets are so huge that they could not and would not react to some trading by a handful of futures speculators in Arkansas, or anywhere else. The markets can and do react suddenly to unforeseeable factors such as war, hurricanes, floods, frost, rain, drought, inflation, economic pacts between countries, and more. But information that causes sudden price changes is often the type of news available to all in news reports, political announcements, and government crop reports. In a word, there have been far more charges of illegal activities, arrests and convictions concerning the stock market than similar charges, arrests and convictions concerning the futures market. Almost no comparison.
