Two of the market’s best-known valuation indicators are sending the same clear message: Stocks are expensive right now.
The Buffett indicator, which measures the total value of U.S. stocks against U.S. gross domestic product (GDP), is nearly 240%, the highest it’s ever been. Keep in mind that in a past Forbes article, Warren Buffett said famously that investors were “playing with fire” when this ratio approached 200%.
The Shiller CAPE ratio, which measures stock prices against inflation-adjusted earnings from the previous 10 years, currently clocks in at 41.5. The only time that figure has ever been higher was during the peak of the dot-com bubble.
It’s clear that stock market valuations are a concern for investors. But does that mean it’s time for investors to actively reduce their stock exposure? History suggests there’s a better course of action.

There’s no denying that U.S. stocks are expensive
Studies have shown that valuations are inversely correlated with forward-looking stock market returns. In other words, more expensive stocks tend to have lower returns in future years and vice versa.
From a short-term perspective, that could be a warning that investors should plan for multiple years of lower returns than they’ve become accustomed to over the past several years.
But it’s important to remember that the Buffett indicator and the Shiller CAPE ratio are just valuation measures. They’re not buy/sell signals, and they don’t indicate that a market crash is imminent. They’re just saying that stocks are expensive compared to historical norms.
Think about it this way. The Buffett indicator reached around 140% during its dot-com bubble peak, and it didn’t hit that level again until January 2018. But let’s imagine you decided to sell at that point in 2018, arguing that stock prices were historically high and were about to crash just like last time.
Granted, you would have missed the COVID-19 recession and the 2022 bear market by doing that. But you’d also have missed a 230% total return in the S&P 500 (^GSPC -0.77%) since that point as well.
Over the long term, stocks usually do just fine
Even though stocks are pricey right now, and even if this does lead to a short-term period of low or negative returns, it’s important to remember that stocks go up far more often than they go down.
Since 1932, the average bear market lasted about 1.5 years and resulted in a loss of 35%. But the average bull market lasts nearly five years and produces an average return of 177%.
If we look at the 10-year rolling total return for the S&P 500 over the past few decades, there’s only been one time when it fell into negative territory.
That was during the “lost decade” of the 2000s, which included historic bear markets around both the dot-com bubble and the financial crisis. Most of the time, however, the rolling 10-year return was at least 100%. For the past decade, that figure has been above 200% much more often than not.
The overall point is that corrections and bear markets are normal, and you should expect to encounter them from time to time. But if you’re a long-term investor and ride out those downturns, stock values usually recover and go on to establish new highs.
What I’d do right now
Current high valuation levels shouldn’t be ignored. I’d expect that this could lead to several years of below-average returns for the S&P 500, given how much good news and future growth are already being priced into stocks.
But I wouldn’t necessarily alter a long-term allocation to account for this. As we’ve seen in the past, expensive doesn’t mean stocks can’t get more expensive. And trying to adjust your allocation is essentially trying to time the market, which can be difficult to do effectively.
Rebalancing within the equity portion of your portfolio could make some sense. Taking some of your investment in a tech ETF and shifting it to a low-volatility ETF is a way to reduce volatility in your portfolio while maintaining your long-term allocation. But you should really only make major changes to a long-term allocation if your objective, time horizon, or risk tolerance changes.
Current stock valuations are worth watching. But you shouldn’t necessarily fear them.
