Advantest (6857) jumped to JPY 36,820 at the Tokyo Stock Exchange morning close on Thursday, October 29, 2026, gaining 5.41% from the previous close after the company reported first-half results and raised its outlook for the fiscal year ending March 2027.
Higher outlook on AI chip-testing demand
The company lifted its full-year revenue forecast to JPY 1.863 trillion from JPY 1.714 trillion, operating income to JPY 967 billion from JPY 846 billion, and net income to JPY 741.5 billion from JPY 660 billion.

Advantest linked the performance to sustained AI-related investment and stronger demand for system-on-chip and memory semiconductor testers.
