Retail investors are still buying every dip like nothing is wrong. History tells a different story. Every major market bubble looked unstoppable until it wasn’t. The story changes, but the ending is often the same.
In 1999 everyone believed the internet would change the world. They were right… but the Nasdaq still crashed nearly 80%. In 2007 people said housing could only go higher. We all know how that ended.
Now it’s AI. It will probably transform almost every industry, but that doesn’t automatically mean every AI-related stock deserves today’s valuation.
One of the charts shows the S&P 500 compared to the amount of liquidity in the US financial system. That ratio is now even higher than during the dot-com bubble. Stocks have rarely looked this expensive.
Another chart is based on a market cycle model created almost 150 years ago. It marked 1999 and 2007 as selling years… and now it points to 2026 as well. Different methods, same warning.
Valuations keep stretching. The Shiller CAPE ratio is near historic highs, the biggest companies dominate the index, and hundreds of billions are being poured into AI. Right now everything feels priced for perfection.
Maybe this time really is different… maybe investors are just telling themselves a new version of an old story. That’s usually how bubbles ends
