Lattice Semiconductor Shares Drop as Chip Sector Faces Pressure

On Oct 12, shares of Lattice Semiconductor, Amkor, Himax, Teradyne, and Kulicke and Soffa fell after concerns over memory chip competition and Taiwan labor tensions pressured the broader semiconductor sector, according to financial reports.

According to TipRanks, Chinese chipmaker ChangXin Memory Technologies announced progress on a next-generation 4F² DRAM server-memory design expected by late 2026. The company plans denser DDR5 enterprise server modules that compete with architectures developed by Samsung Electronics and SK Hynix.

TipRanks noted that ChangXin Memory Technologies has not yet demonstrated commercial-scale manufacturing capability for the new chips. The development contributed to investor concerns about future competition in the memory market.

Reuters, through Investing.com, reported that labor tensions in Taiwan also affected sentiment around Micron. A total of 1,994 Taoyuan union members, representing 99% of ballots cast, voted to authorize a strike seeking a permanent 15% profit-sharing bonus.

According to Investing.com, Micron facilities in Taiwan employ 15,000 workers and support the company's DRAM and high-bandwidth memory production. No strike date had been set at the time of the report.

Memory manufacturers including Micron, SanDisk, and SK Hynix declined in early trading as investors assessed potential supply chain risks. Financial media reported that the iShares Semiconductor ETF also fell 1% during premarket activity.

Lattice Semiconductor shares declined 1.9%, while Amkor dropped 2%, Himax decreased 3.1%, Teradyne fell 3.3%, and Kulicke and Soffa lost 2.6%, according to market data cited in the report.

Teradyne experienced the largest decline among the listed companies. The company has recorded 60 moves above 5% over the past year, and the latest drop reflected market sensitivity to semiconductor industry developments.

Five days earlier, Teradyne shares had fallen 5.1% after rising 10-year Treasury yields increased concerns about borrowing costs. CNBC reported that the 10-year Treasury yield moved above 5.3% and reached its highest level since 2002.

According to CNBC, Federal Reserve meeting minutes showed most officials expected another federal funds rate increase could be appropriate by year-end, while decisions would continue to depend on incoming economic data.

Teradyne shares were up 85.9% since the beginning of the year but remained 20.2% below their 52-week high of $483.84 from June 2026. The stock traded at $385.90 per share in the report.
