Key Facts

Semiconductor shares jumped after the Bureau of Labor Statistics reported that U.S. nonfarm payrolls increased by only 29,000 in September, significantly missing economist expectations. FinancialContent reported that the unemployment rate rose to 4.2%, a move that cooled Treasury yields and eased valuation pressure on growth-oriented technology equities.

The upward trend impacted several key players, with Microchip Technology (MCHP) closing at $78.5 and Monolithic Power Systems (MPWR) at $1,360.97 on October 1, 2026. Additionally, Impinj (PI) closed at $183.87 and Power Integrations (POWI) finished the same session at $51.5, as the weaker labor data increased expectations for lower interest rates which typically reduce borrowing costs for the semiconductor sector.
