Japanese Exporters Ride Weaker Yen Wave

Japan's recent currency intervention has put Japanese exporters under scrutiny, particularly those with overseas sales. The weaker Yen can boost earnings for companies like Disco Corporation (TSE:6146), which supplies precision cutting equipment to chipmakers and electronics manufacturers.

Disco generates almost all of its revenue from its Precision Processing Systems business, with a market cap of ¥6,343.2 billion. A weaker Yen can make its export-heavy earnings more valuable when translated back into Yen, justifying a premium valuation.

However, the company's rich P/E ratio of 43.5x and reliance on external borrowing may raise concerns among investors. Additionally, Tokyo Electron (TSE:8035) and Advantest Corporation (TSE:6857) also benefit from a weaker Yen due to their export-heavy earnings.
