Shares of Qualcomm Inc., the biggest maker of chips that run smartphones, slid after the company gave a tepid revenue forecast, underscoring concerns that tariffs will hurt demand for its products.Revenue in the period ending in June will be $9.

Mobile chip designer Qualcomm on Wednesday forecast third-quarter revenue that would not meet estimates, joining other tech companies such as Snap and Samsung that voiced concerns about the effects of U.

Overall the results were not too bad, but investors were clearly disappointed with the light revenue guidance, as Qualcomm’s stock fell 5% in extended trading. That means the stock is now down 3% in the year to date, though it’s doing better than the broader iShares Semiconductor exchange-traded fund, which is down 15% this year.
