Why is Trend Micro stock sliding today?

Trend Micro's stock experienced a significant decline of 8.4% on August 14, trading at ¥5,361 on Monday, after the company announced a reduction in its full-year guidance. The company slashed its FY2026 net profit forecast by around 11%, attributing the decrease to the substantial cost burden resulting from intensified investments in AI infrastructure, cloud expansion, and new business branding initiatives.

On a positive note, Trend Micro's underlying H1 2026 results showed a robust revenue growth of 11.0% year-on-year, reaching ¥148.6 billion, primarily due to the widespread adoption of its Vision One AI-powered cybersecurity platform. However, the company's operating profit plummeted by 23.5% to ¥21.8 billion, exacerbating the stock's downward trajectory.

The combination of this profit shortfall and the formal full-year guidance cut led to the stock hitting its daily limit-down, with the session closing at ¥5,851, which now represents today's previous close.
