Watch our latest quarterly review video for a comprehensive analysis on historic valuations and the power of diversity
Congratulations, we made it! We've reached the end of another quarter with strong investment returns. But there's something important you should know: The U.S. stock market is now at the third most expensive level in history. The previous two times were 1929 (Great Depression) and 1999 (tech bubble).
Before you panic…this doesn't mean a crash is imminent. But it does provide important context for what to expect and why diversification matters more than ever.
This chart shows the Schiller price-to-earnings ratio, which averages earnings over 10 years. You can see spikes in 1929, 1999, and today at similar levels.
When valuations are this high, historical data suggests S&P 500 returns over the next five years will likely be in the single digits—probably around 5% per year, well below the historical average.
Most people think the S&P 500 divides money equally across 500 companies. It doesn't.
The S&P 500 is weighted by market capitalization. Right now, the top 10 stocks represent approximately 40% of the entire index. When you invest in the S&P 500, 40% goes into just 10 companies: NVIDIA, Apple, Amazon, Microsoft, Google, and a few others.
We've never had the S&P 500 be so concentrated in so few names.
If you look at this valuation chart historically, stocks became permanently more expensive starting around 1995. If you had used valuations to time the market, you would have been sitting on the sidelines since 1995—missing decades of returns.
Valuation is useful for setting expectations, but it's a terrible tool for market timing.
Here's the good news: We don't need to time the market because we diversify beyond U.S. large-cap stocks.
Quarry Hill client portfolios include:
All of these have much more reasonable valuations right now.
While U.S. stocks have become increasingly expensive, international stocks have remained at historically cheap levels. International valuations haven't meaningfully increased since 2008, even as U.S. valuations soared.
At Quarry Hill, we use global market cap weighting—about 60% U.S. stocks and 40% international. We're not overweighting the most expensive market in the world.
While U.S. large-cap stocks are extremely expensive, small value stocks are trading at normal historical valuations. This is why our portfolios tilt toward small cap value—we're leaning away from expensive areas toward historically higher-returning assets with better valuations.
This chart shows what happened starting January 1, 2000—the tech bubble burst. An S&P 500 investor lost almost 44% by October 2000. After five years, their cumulative return was -11% (averaging -2% per year).
A diversified index portfolio with a small value tilt achieved a positive return of 55% over those five years—9% per year after all fees, including our 1% advisory fee.
A well-diversified portfolio did just fine through the tech bubble.
How are we positioning Quarry Hill portfolios today?
The U.S. market is expensive and concentrated—but don't try to time it. You'd have been out since 1995.
Diversification is your protection—spreading across international markets, small value stocks, and bonds lets us lean away from expensive areas without risky all-or-nothing bets.
Our clients are positioned differently—with better valuations in international and small value stocks.
History shows diversification works—even during extreme valuation bubbles.
Discipline drives returns—not predictions, but adherence to research-based strategy.
We're invested alongside you. You can't predict the future, but you can prepare for it:
