Texas Instruments Suffers Worst Rout Since ’08 on Tepid Forecast

Texas Instruments Inc., a key chipmaker for producers of cars and factory equipment, suffered the worst stock decline in 17 years after stoking fears that a tariff-fueled sales surge will be short-lived.

Though the company issued a third-quarter forecast on Tuesday that beat most estimates, the outlook was more guarded than some investors had anticipated. The stock fell further during a conference call, when executives struggled to win over analysts who said the company’s tone had become increasingly negative.
