Recently, we've seen a notable rally in Japanese stocks related to electronic components and factory automation.
The surge is primarily fueled by three key factors. First and foremost is the AI hardware boom. Modern AI servers require a vast number of high-end Multi-Layer Ceramic Capacitors (MLCCs)—sometimes tens of thousands per unit. This explosive demand has created a significant supply bottleneck. As a result, top-tier Japanese suppliers like Murata and Taiyo Yuden, who are running their factories at very high utilization rates, are regaining the power to raise prices, which directly boosts their profit margins.
Second, the weak Japanese yen provides a powerful tailwind. With the USD/JPY exchange rate hovering around 159, Japanese exporters see their overseas profits translate into more yen. This currency advantage is supported by the Bank of Japan's cautious approach to normalizing its monetary policy, suggesting that the yen may remain relatively weak for some time. This makes Japanese products more competitive globally and inflates reported earnings.
Third, there's a strong domestic demand for equities. Recent corporate governance reforms and the expansion of the Nippon Individual Savings Account (NISA) program have encouraged Japanese households to shift their savings into the stock market. This steady flow of domestic capital into quality industrial and technology companies provides a solid foundation for their stock prices.
This rally isn't a sudden event but the culmination of trends that have been building for months. We saw early signs in late 2025 with reports of high factory utilization rates. More recently, these signs have materialized into concrete actions like supplier price hikes and strong corporate earnings guidance, validating the positive outlook and fueling investor confidence.
