Did a Big Bet Help Trigger ‘Black Swan’ Stock Swoon?

I wouldn’t call this a "black swan" event any more than Jon Stewart would call it a "perfect storm." Felix Salmon – it’s a silly theory – Nassim Taleb Didn’t Cause the Crash makes a better argument below. – Ilene  

Did a Big Bet Help Trigger ‘Black Swan’ Stock Swoon?

Red Bull Air Race Perth - Training Day

By SCOTT PATTERSON And TOM LAURICELLAWSJ

Shortly after 2:15 p.m. Eastern time on Thursday, hedge fund Universa Investments LP placed a big bet in the Chicago options trading pits that stocks would continue their sharp declines.

On any other day, this $7.5 million trade for 50,000 options contracts might have briefly hurt stock prices, though not caused much of a ripple.

The trade by Universa, a hedge fund advised by Nassim Taleb, author of "Black Swan: The Impact of the Highly Improbable," led traders on the other side of the transaction—including Barclays Capital, the brokerage arm of British bank Barclays PLC—to do their own selling to offset some of the risk, according to traders in Chicago.

Lots of options trades of that size take place every day, and just because this one happened just before the market fell doesn’t mean it was the cause of the crash.

It’s becoming increasingly clear that the crash was fundamentally the fault of weak market structures, especially in the smaller electronic exchanges. It wasn’t a fat finger, it wasn’t cyberterrorism, it wasn’t the sale of 16 billion e-mini S&P contracts rather than 16 million — and it wasn’t an options trade by Universa, either…
