Advantest stock was trading at EUR 221.70 at Lang & Schwarz on October 2, 2026 at 2:39 p.m. CEST, up 5.71 percent versus the prior close of EUR 209.73. As Investing.com reported on October 2, 2026, renewed optimism around AI chip demand helped push the semiconductor testing specialist to a record level on its Tokyo listing.
AI demand reaches test systems
Investing.com attributed the move to stronger expectations for chipmakers after Micron Technology reported better results and guidance for high-bandwidth memory demand. Advantest supplies test systems used to check advanced chips before shipment, giving the company direct exposure to the expansion of AI infrastructure.
The same report said Advantest reached an intraday high of JPY 39,580 on October 2, 2026, matching its 52-week high. That places the current market story at the intersection of operating momentum and elevated technical expectations.
First-quarter figures set the bar
Parqet reported that Advantest's first-quarter fiscal 2026 revenue reached JPY 367.5 billion, up 39.30 percent year over year. Operating profit rose 53.30 percent to JPY 190.0 billion, while net income increased 93.80 percent to JPY 174.8 billion.
The figures show why AI-related demand matters more than a simple share-price breakout. Operating profit grew faster than revenue in the first quarter, but the coming report will test whether that operating leverage continues as customer demand broadens beyond the strongest AI applications.
October 28 results date
Advantest's investor-relations calendar says the company plans to announce second-quarter fiscal 2026 results on October 28, 2026, at 3:30 p.m. JST, per Advantest. The date gives the market a defined test for the elevated earnings expectations now reflected in the stock's record Tokyo level.
Record high meets valuation test
Advantest's market capitalization was JPY 28.0 trillion as of October 2, 2026, while its 52-week range was JPY 14,920.00 to JPY 39,580.00. The valuation leaves the next results as the clearest near-term event for judging whether first-quarter growth can support the market's higher expectations.
The euro reference price was EUR 221.70 at Lang & Schwarz on October 2, 2026 at 2:39 p.m. CEST, up 5.71 percent versus the Lang & Schwarz prior close of EUR 209.73 on October 1, 2026. The further course of trading is shown by the continuously updated real-time quote of Advantest stock.
