Teradyne (TER), Monolithic Power Systems (MPWR) Slide in Broad Chip Selloff Triggered by Broadcom Guidance and Jobs Data

Shares of Teradyne (TER) and Monolithic Power Systems (MPWR) fell sharply on June 5, 2026, swept up in a global semiconductor rout. The selloff was triggered by a disappointing revenue forecast from Broadcom (AVGO) and a stronger-than-expected U.S. jobs report, which wiped out near-term interest rate cut expectations. The downturn struck chipmakers worldwide. South Korea's Kospi index dropped 5.5%, with SK Hynix losing nearly 10%. In Europe, ASML fell 3.8% and Infineon declined more than 6%. Broadcom's guidance miss reset the timeline for hyperscaler AI chip spending, removing a key growth catalyst for the sector. The 172,000 nonfarm payroll print then introduced potential rate hike risk by year-end, per CME FedWatch, pressuring richly valued semiconductor stocks sensitive to discount rate shifts. Teradyne, known for extreme volatility with 41 moves greater than 5% in the past year, saw the decline as a meaningful but not business-altering market reaction. The stock remains up 81.2% year-to-date, trading at $376.11 and still 10% below its April 2026 high of $418.08.
