This Stock Market Valuation Metric Just Hit a Two-Decade High. Here's What History Says the S&P 500 Does Next.

The cyclically adjusted P/E ratio, or CAPE ratio, measures the S&P 500's total price-to-earnings ratio based on the past 10 years' worth of average earnings, adjusted for inflation. The CAPE ratio is at its highest level in more than 25 years and the second-highest ever, …

This Stock Market Valuation Metric Just Hit a Two-Decade High. Here's What History Says the S&P 500 Does Next.

The high CAPE ratio points to a market correction coming sooner rather than later, but the future is unknown. The S&P 500 has always recovered and gone on to soar to new heights after any market crash or correction, and it's the best path to wealth for many Americans.

Why it matters

Investors need to keep in mind that any market plunge could be deep and long, and they should plan accordingly. A diversified portfolio with around 50 stocks, plenty of which should be in the defensive and value sectors, can help investors feel confident about the long-term future of the market.

Imagine you're at a big party, and everyone is having a great time. But then, someone starts playing music that's too loud, and people start to get uncomfortable. That's kind of like what's happening with the stock market. The music is getting too loud, and people are starting to get worried. But just like how the party will probably calm down eventually, the stock market will probably recover too.

Analysis

A $60B Vote of Confidence

The cyclically adjusted P/E ratio, or CAPE ratio, measures the S&P 500's total price-to-earnings ratio based on the past 10 years' worth of average earnings, adjusted for inflation. This metric is considered more reliable than the standard average P/E ratio because it smooths out the distortions of any one unusually good or bad year. The CAPE ratio is at its highest level in more than 25 years and the second-highest ever, reaching 44 in 2000 during the dot-com bubble.

Why Bulls Are Wrong

Bulls might say that this time is different from the dot-com bubble, because AI companies are highly profitable. However, that doesn't address the mounting CAPE ratio; companies may be profitable, but their stock gains are still outpacing their profit growth. Many of the most important AI companies are hyperscalers with decades-long track records of profitability, cash generation, and overall success. However, there are many smaller AI-driven companies that rely on continued hyperscaler spending to keep growing and retain their high valuations, and many of these companies are barely profitable or not profitable at all, yet may sport fantastic valuations.

A Correction Is Coming

There may not be an imminent market crash, but a correction is coming at some point. The high CAPE ratio points to it coming sooner rather than later, but the future is unknown. The positive news for investors is that the market has always recovered and gone on to soar to new heights after any market crash or correction, and it's the best path to wealth for many Americans. In fact, the S&P 500 has gained 742% since it recovered in 2003. Investors need to keep in mind that any market plunge could be deep and long, and they should plan accordingly. That includes building a diversified portfolio with around 50 stocks, plenty of which should be in the defensive and value sectors. Then, you can be comfortable investing in growth stocks, too, and feel confident about the long-term future of the market.

Key points

  • The cyclically adjusted P/E ratio, or CAPE ratio, is at its highest level in more than 25 years and the second-highest ever.
  • The market may be frothy, but a correction is coming at some point.
  • A diversified portfolio with around 50 stocks, plenty of which should be in the defensive and value sectors, can help investors feel confident about the long-term future of the market.
  • The S&P 500 has always recovered and gone on to soar to new heights after any market crash or correction, and it's the best path to wealth for many Americans.
The Upside

If the market corrects, investors can expect a recovery and potentially even higher gains in the long term. A diversified portfolio with a mix of defensive and value stocks can help investors feel confident about the future.

The Downside

If the market crashes, investors could face significant losses and a prolonged recovery period. It's essential to have a well-diversified portfolio and a long-term perspective to navigate such a scenario.
