Does This Remind Us That Investment Opportunities Are Global and Should Not Be Limited to Domestic Stock Markets?

Yes, Warren Buffett’s investment strategy offers profound insights. His investment in Japan’s Five Major Trading Houses (e.g., Itochu, Mitsubishi Corporation) serves as a vivid example of global opportunities. This not only reflects Buffett’s consistent value-investing philosophy but also reminds investors to look beyond their home markets and embrace a global perspective for better asset allocation and risk diversification. Below is an analysis from several angles:

1. Background and Lessons from Buffett’s Investment in the Five Trading Houses

Through Berkshire Hathaway, Buffett began investing in Japan’s Five Major Trading Houses around 2020. These companies operate in energy, trading, and resources and were viewed as undervalued quality assets.
Despite Japan’s long-term stock market stagnation, Buffett recognized their strengths: stable cash flows, high dividends, and global business reach. This investment has since delivered substantial returns, proving the value of cross-border opportunity identification.
Key Takeaway: Investment opportunities extend beyond one’s home country. Even when domestic markets (e.g., U.S. stocks) thrive, overseas markets like Japan may harbor "undervalued gems," underscoring the importance of a global outlook.

2. Advantages of Global Investing

Risk Diversification: Focusing solely on domestic stocks exposes portfolios to local economic cycles, geopolitics, or policy shifts (e.g., inflation, rate changes). Global investing spreads risk—seeking growth in emerging markets or stability in developed ones.
Broader Opportunities: Unique industry strengths exist across nations (e.g., tech in the U.S., manufacturing in Germany, resources in Australia). Ignoring these may mean missing "bargain-hunting moments" like Buffett’s.
Currency and Valuation Opportunities: Exchange-rate fluctuations and regional valuation gaps (e.g., Japan’s low P/E ratios) can generate additional returns and enhance portfolio resilience.

3. Investment Strategies and Asset Allocation Recommendations

Adopt a Global Lens: Build an international portfolio via ETFs, index funds, or direct stock investments. For example, allocate 20–30% of assets to overseas markets.
Learn from Buffett: Prioritize fundamental analysis over short-term volatility. Assess global companies’ competitive advantages, economic moats, and management quality.
Mind the Risks: Global investing involves currency risks, regulatory differences, and information asymmetry. Start small or consult professional advisors.
Asset Allocation Principles: Balance stocks, bonds, and alternative assets based on age and risk tolerance, ensuring global diversification. Younger investors may increase exposure to emerging markets; older investors may favor stable developed markets.

In summary, Buffett’s actions remind us: investing knows no borders, and opportunities exist worldwide. Focusing solely on domestic markets is akin to "viewing the sky from the bottom of a well," while a global vision enables more sustainable wealth growth. In an era of heightened geopolitical uncertainty, this strategy is especially invaluable.
