US stock futures posted modest gains Thursday as bond yields stabilized near multi-year highs and investors digested latest commentary from Federal Reserve Governor Christopher Waller. Chip stocks fell after Broadcom Inc.’s results.
Futures contracts tied to the S&P 500 Index were up less than 0.2% as of 8:35 a.m. in New York after Waller said his next decision on interest rates will be “heavily influenced” by August inflation data due next week. Nasdaq 100 futures were little changed.
Broadcom shares fell 3.3% premarket after the chipmaker’s results and forecast were seen as underwhelming, even as it predicted a boom in artificial intelligence chip sales over the next two years. An exchange-traded fund tracking chip names fell 1.3% ahead of the opening bell.

Investors are gearing up for Friday’s jobs report for clues on the Fed’s path for interest rates. Economists estimate that the employment report, due at 8:30 a.m. in Washington on Friday, will show US employers added 55,000 jobs in August. Such a result would be broadly in-line with average job growth this year.
The S&P 500 is projected to swing just 0.7% in either direction on Friday, in line with the average realized move on jobs-report days over the past 12 months, options-market data compiled by Citigroup Inc. show. Stuart Kaiser, the firm’s head of US equity trading strategy, says Friday’s implied move, based on prices of S&P 500 option straddles as of Tuesday’s close, is too low.
