The U.S. stock market's latest run to all-time highs could be giving investors a false sense of security.
Market watcher Marc Faber, often hailed as the original "Dr. Doom," is not backing down from his long-held correction warning — even though nothing has materialized.
"You don't see, and I don't see. And, nobody sees. That's why people keep buying stocks. And yet, something will happen one day," the publisher of "The Gloom, Boom & Doom Report" said Tuesday on CNBC's "Futures Now."
Faber, who's in his 70s, is convinced another financial crisis like 2008 will happen in his lifetime and it'll come when Wall Street least expects it. He predicted in late June that stocks will fall 40 percent.
He said several scenarios could trigger a deep correction.
"I think it may very well come from a credit event. Or, it may come from the disclosure of a major fraud. Or, it may come because interest rates start to go up," he said.
"In 2009 when stocks bottomed out, I can tell you that not many people saw why stocks would go up," Faber said. "Now it's the opposite. The sky is clear. Corporate profits have been expanding — they're good. Interest rates are low, but valuations are very high."
