"On October 27, 1997, losses resulting from this investment, combined with a 554-point (7.2%) single-day decline in the
Dow Jones Industrial Average (the eighth
[20] largest point decline to date in index history), forced Niederhoffer Investments to close its doors. In a lawsuit that Niederhoffer later filed in the
U.S. District Court for the Northern District of Illinois against the
Chicago Mercantile Exchange, where he traded
options, he alleged that
floor traders colluded to drive the market down that day to force him out of his positions. Traders at the time said
Refco may have been responsible for as much as $35 million of Niederhoffer's losses.

-This is why you hedge. If he had hedged instead of doing naked shorts like the majority of the big shot investors, fund managers, traders and etc. who lost and blew up their accounts, his investment funds would've still survived. He might have still lost (very few people can survive a 7.2% drop in the market when betted the wrong way) but he would've still had money left to invest/trade.
Shorting options have extremely high probability of winning but when you lose, you lose huge, wiping out all of your gains. That's why the premiums are priced so high. Tail risk, my friend, tail risk. And the guy studied statistics. LOL Guess he fell asleep in class the day when they were talking about outliers.
At least he had the money to sue, this guy didn't after he did exactly the same thing 10 years ago:
