Micron Technology Inc. shares were among AI infrastructure stocks trading lower in Monday premarket action as US equity futures extended the previous week’s losses. S&P 500 futures fell 0.3%, Nasdaq futures dropped 1% and Dow futures edged marginally lower, with technology weakness compounded by concerns about deteriorating macroeconomic conditions. Micron, Marvell and Sandisk were down between 3.5% and 5% in premarket trading, while Nvidia was little changed ahead of its earnings report on Wednesday after the bell. One premarket reading put Micron down 3.46% at $933.31. The broader retreat reflects uncertainty over returns on heavy AI infrastructure investment, although potential initial public offerings from large-language-model developers are providing some support. Oil prices eased but remained elevated after the US pledged to isolate Iran economically, adding to inflation concerns as high energy costs amplify the effects of deficit spending and Treasury bond buybacks. Micron remains in a longer-term uptrend but has weaker short-term momentum and a low Value score, leaving it more sensitive to risk aversion. Its next major catalyst is an earnings report estimated for Sept. 22, with analysts expecting earnings of $31.26 per share and revenue of $50.78 billion, compared with $3.03 per share and $11.31 billion a year earlier.
