US futures slip as Micron slides, with data on deck

US stock futures retreated on Thursday after chipmaker Micron’s (MU) outlook put a dent in tech-rally hopes, as investors braced for fresh economic data ahead of an inflation reading key to Federal Reserve policy.

S&P 500 futures () dropped roughly 0.2%, after rising Wednesday to close not far short of a new all-time high. Futures on the Dow Jones Industrial Average () and the tech-heavy Nasdaq 100 () also fell about 0.2%.

Stocks are struggling in the wake of Micron’s sales forecast for the current quarter, which met expectations but failed to satisfy investors looking for stellar outperformance from AI-linked companies.

Bullishness around AI has helped lift the benchmark S&P 500 (^GSPC) to a 15% gain this year. But concerns are growing that the rally could be at risk if the handful of tech companies driving most of those gains stop topping already lofty expectations.

Memory maker Micron’s shares slid almost 6% in pre-market trading. Nvidia (NVDA) was down 1.6%, reviving worries of a return to the sell-off that rattled markets last week, as other AI chip stocks came under pressure.

Focus is also on updates on GDP and weekly jobless claims due before the market open, a day ahead of the PCE inflation print on Friday that will influence the Fed’s thinking on timing of interest-rate cuts. A continued rise in unemployment claims would cement growing concerns about softening in the labor market.

Inflation could also loom large in the first debate between President Joe Biden and former President Donald Trump on Thursday night.

On the corporate front, Levi Strauss (LEVI) shares sank over 15% in the wake of a second-quarter revenue miss for the jeans seller. Investors will look to Nike’s (NKE) quarterly results after the bell for more clues to consumer resilience.
