Wall Street’s Pricey Problem: Are U.S. Stocks Too Expensive to Deliver Big Returns?

​The U.S. stock market has been on a wild ride, but here’s the problem: stocks are expensive—really expensive. And that could mean disappointing returns for years to come.

Right now, the U.S. dominates the global market. American stocks make up two-thirds of the world’s market value, even though the U.S. economy is only a quarter of global GDP and has just 4% of the world’s population. That’s a massive imbalance—and it’s starting to show cracks.

The Market Is Acting Strangely—And It Might Be a Warning Sign
Historically, U.S. stocks and international markets have moved in sync, with a strong correlation of 0.83 (on a scale where 1 means they move identically). But in the last 100 days, that correlation has dropped to 0.54—a major statistical shift that happens only 0.3% of the time.

What’s causing this divergence?
✔ Trump’s election and tariff threats boosted U.S. stocks and the dollar.
✔ Recent policy shifts and geopolitical changes have helped foreign stocks surge while U.S. stocks lag.
✔ The “Magnificent 7” tech giants (like Nvidia), which have fueled most of the stock market gains, are losing steam.

​U.S. Stocks: Too Expensive for Their Own Good?
According to Research Affiliates, large U.S. growth stocks are trading at near-record valuations—more expensive than 98% of past market conditions. Meanwhile, international value stocks are at the opposite extreme, ranking in the cheapest 2% of history.

That’s a giant valuation gap, and history suggests it could mean low returns for U.S. stocks over the next decade.

✔ Expected 10-year return for U.S. large growth stocks: 1.8% per year (negative after inflation).
✔ Expected 10-year return for international value stocks: 10% per year.
✔ Emerging markets value stocks? 10.5% per year.

Translation: If history holds, investors clinging to pricey U.S. stocks might be in for a rough decade.
​
​Where Are the Bargains?
Looking for cheaper alternatives? Some global markets are still trading at historical discounts:
✔ Brazil (9th percentile) – Historically cheap.
✔ Hong Kong (7th percentile) – Beaten down but could rebound.
✔ Turkey (22nd percentile) – Risky, but deeply undervalued.

Meanwhile, Europe—often written off by investors—is still at its 76th percentile, meaning it’s not dirt cheap, but also not overpriced.
​
​What This Means for Investors
1️⃣ U.S. stocks might not be the “only game in town” anymore.
2️⃣ Foreign value stocks could outperform for the next decade.
3️⃣ Investors may need to rethink their “America-first” investing strategy.

For years, Wall Street has been obsessed with U.S. tech giants. But if valuations are any indication, the next big winners might not be in Silicon Valley—but overseas.
