Advantest gains on AI test demand, guidance raise; China and payback fears weigh
AI test demand and raised guidance Advantest benefits from strong demand for AI chip testing and raised its full-year net profit guidance to ¥660bn. The stock surged on robust earnings and SEMI's forecast of 23.2% equipment sales growth in 2026.
This is the main positive force behind the stock's performance in July.
Silicon photonics partnership and duopoly pricing power Advantest formed a silicon photonics partnership with OpenLight and holds duopoly pricing power with Teradyne, controlling 85–90% of the market. This strengthens its competitive position and pricing ability.
It highlights a new partnership and structural advantage supporting the stock.
AI-spending payback fears and China competition Fears that AI spending may not pay off triggered sharp selloffs, with the stock down 6–10% in July. China's chipmaking advances (Yuliangsheng, CXMT) threaten oversupply and competition, while Moonshot's open-weight AI model renewed concerns about faster Chinese progress.
These are the key risks that caused volatility and downward pressure.
Macro and cost pass-through worries Apple/Microsoft AI cost pass-through worries, Middle East tensions, and oil prices add further volatility. The stock remains highly sensitive to sentiment swings despite solid fundamentals.
These external factors contributed to price swings and investor uncertainty.
