Keywords: Optical communication sell-off, AI demand concerns
1. On October 8, 2026, Applied Optoelectronics, Lumentum, and the Photonics ETF declined simultaneously. Coherent experienced a concentrated profit-taking with the optical communication sector. Since the beginning of this year, the company has risen by 68.32%, with a significant earlier increase, so the pressure for a pullback has intensified.
2. On October 9, 2026, expectations for OpenAI's annualized revenue fell below previous levels, Oracle's data center power constraints, and a decline in Oracle’s stock price weakened expectations for AI infrastructure demand. Related optical communication and AI hardware stocks also weakened simultaneously.
3. On October 8, 2026, the yield on U.S. Treasury bonds remained high, while the S&P 500 and Nasdaq 100 moved lower. Macro interest rate pressure increased the valuation correction pressure on high-valuation tech stocks; Coherent's forward P/E ratio is about 36.1 times.
