As expectations of a shift in the Federal Reserve's interest rate policy in July 2026 heat up, valuations of major US stock indices have climbed to historically high levels. According to the latest capital flow data, global institutional investors are accelerating the shift of funds from US stocks to Asia-Pacific markets, especially stock markets with growth potential such as Thailand, Japan, and Taiwan. This article will deeply analyze current cross-market valuation differences and provide practical sector rotation ideas.
US Stock Valuation Pressures Emerge
As of July 24, the S&P 500 index P/E ratio is about 22.5 times, far higher than the 10-year average of 18 times. The Nasdaq index, concentrated in technology stocks, has a P/E ratio as high as 28 times, reflecting that the market's optimistic expectations for AI and cloud computing have been partially exhausted. A Morgan Stanley report points out that if the Federal Reserve maintains high interest rates for a longer period, US stocks may face a correction risk of 10-15%.
Relative Attractiveness of Asia-Pacific Markets
In contrast, valuations of major Asia-Pacific stock markets are more advantageous: the Thailand SET index P/E ratio is about 14 times, the Japan TOPIX index about 15 times, and the Taiwan Weighted Index about 16 times. More importantly, corporate earnings growth momentum in these markets continues to improve. Thailand benefits from tourism recovery and electric vehicle supply chain deployment, with an estimated EPS growth rate of 12% in 2026; Japan, due to corporate governance reforms and share buyback waves, continues to attract foreign capital inflows.
Cross-Market Sector Rotation Strategies
For investors seeking to diversify risk, we propose the following sector rotation ideas:
- Technology stocks: US semiconductor and AI stocks are overvalued; investors can shift to Japanese semiconductor equipment makers (e.g., Tokyo Electron) and Taiwanese wafer foundry leaders, which have lower P/E ratios and similar growth momentum.
- Financial stocks: Thai bank stocks benefit from widening interest rate spreads at the end of the rate hike cycle, and non-performing loan rates continue to decline; US bank stocks face deposit cost pressure.
- Consumer stocks: Yen depreciation boosts Japanese tourism and domestic consumption; Thai retail benefits from returning tourists; while US consumer stocks face earnings downgrades due to inflation stickiness.
Cross-Border Asset Allocation Considerations
When conducting cross-market investments, one should be mindful of exchange rate risks and transaction costs. The Thai stock market has a higher tax burden for foreign investors (dividend tax 10%), while the Japanese stock market offers more favorable tax rates for long-term investors. It is recommended to reduce single stock risk through ETFs or local index funds. In addition, some Asia-Pacific markets have lower liquidity, so the allocation ratio of a single asset should be controlled not to exceed 5% of total assets.
Conclusion
In an environment where US stock valuations are high and Federal Reserve policy uncertainty is rising, shifting some funds to Asia-Pacific markets can not only reduce overall portfolio volatility but also offer the opportunity to enjoy higher dividend yields and growth potential. Investors should adopt systematic sector rotation strategies to find relatively undervalued opportunities across different markets, achieving true global diversification.
