Déjà Vu on Wall Street: Are We Heading for a 1929-Style Market Meltdown?

Tom DeMark, the technical analysis guru who’s made a career of predicting market peaks, is sounding the alarm bells once again. His latest cautionary tale? He’s drawing some eerie parallels between today's market and the lead-up to the 1929 stock market crash. And if you're squinting to see how history might rhyme this time, DeMark's analysis paints a rather concerning picture.

A Historical Echo Chamber?
The numbers that DeMark throws out are hard to ignore. He points out that the Dow Jones Industrial Average, from its 2009 low to today, has surged a staggering 587%. That’s uncomfortably close to the 624% run-up from the December 1914 low to the September 1929 high, just before the crash that plunged the world into the Great Depression. If you're into omens, this one’s practically a neon sign.

But it’s not just about past performance. DeMark uses a proprietary trend exhaustion model—focusing on sequences of 9s and 13s in price movements, akin to a technical analyst's version of counting sheep, but much scarier. According to him, the Dow and S&P 500 are nearing a critical tipping point. The S&P, for example, is at a monthly countdown of 12 or 13, and the Dow is almost at 11 on the daily charts. One or two more rallies, and his models signal it’s game over.

Top of the Roller Coaster?
DeMark’s models suggest the Dow could top out at an optimistic 47,045 (it's currently around 43,751). For the S&P 500, he’s eyeing a possible high of 6,118—though it hasn’t managed to hold gains above the 6,000 mark just yet. If his analysis holds, once these highs are hit, we could be in for a textbook correction, somewhere in the 5% to 10% range, or potentially something much worse.

Adding to the tension is the market’s recent rally, which DeMark describes as being "on stilts." He warns that even the slightest pause in buying could trigger a cascade of selling, turning the market from a bull's playground into a bear's den almost overnight. Basically, the current euphoria feels like it’s balancing on a house of cards.

AI and Nvidia: The Canary in the Coal Mine?
DeMark is also throwing shade at Nvidia, one of the hottest stocks driving the current AI boom. Nvidia has been on an absolute tear, but according to DeMark’s countdown, it’s sitting at a precarious 12—meaning just one more good day could max out its rally. With earnings on deck next week, the pressure is on. DeMark sees Nvidia potentially peaking around $154.50, but he also warns that the downside risks are significant. So if you’re all-in on AI stocks, maybe keep an eye on that sell button.

The Bottom Line: Are We Headed for Another Crash?
It's easy to dismiss doomsayers, especially when markets have been defying gravity for years. But DeMark isn't some random perma-bear—he’s got a track record that has won the respect of big players like Paul Tudor Jones and Steven A. Cohen. And while history doesn’t always repeat, it does often rhyme.

Could the market be setting itself up for a 1929-style crash? Maybe, maybe not. But if DeMark is right, it might be time to take a hard look at those portfolios and buckle up. Because if this roller coaster is nearing the top, the ride down could be fast, furious, and brutal.
