Hedge Fund Pro Spitznagel: Market Set for Spectacular Crash

Scary! This bearish call points to 40% market drop (CNBC)

The stock market is trading at unsustainable levels that could eventually lead to a major sell-off, with a possible 40 percent drop in stock prices, hedge fund executive Mark Spitznagel told CNBC Wednesday.

"The simple answer, the mom and pop answer, I think, is just to step aside," said Spitznagel, founder of Universa Investments and an associate of "Black Swan" pioneer Nassim Taleb.

Spitznagel, incidentally, has some Street cred when it comes to predicting downturns: He called it in 2000 and 2008 and made one of the biggest profits on Wall Street during the 2008 financial crisis, while many other investors were losing money.
