According to Bank of America Securities data cited by SeekingAlpha, eight "blue-collar" semiconductor stocks—Texas Instruments, Analog Devices, NXP Semiconductors, Microchip Technology, onsemi, STMicroelectronics, Infineon, and Monolithic Power Systems—have declined approximately 21% from their June peaks since early July.
These semiconductors are widely used in machinery, automotive, and factory automation applications. As leading indicators of industrial demand, their price movements typically precede shifts in heavy industry activity, making them a closely watched barometer for economic health.
