Morning Movers: Lam Research and Micron dip after Samsung quarterly results

Markets are taking a breather this morning after Monday's rally, with investors rotating out of semiconductor stocks despite blockbuster earnings from Samsung Electronics. Dow futures are modestly higher, while S&P 500 and Nasdaq futures are under pressure as weakness in AI-related names weighs on sentiment. Despite reporting record quarterly operating profit, Samsung shares fell sharply, dragging down chipmakers across Asia and pressuring U.S. semiconductor stocks in premarket trading. Investors appear increasingly concerned that expectations for AI-driven memory demand and infrastructure spending have become difficult to exceed. In addition, oil prices are moving higher after reports that Iranian forces attacked commercial vessels near the Strait of Hormuz, renewing concerns about global energy supplies. While crude remains well below the highs reached earlier this year, the latest escalation serves as a reminder that developments in the Middle East could quickly reintroduce inflationary pressures into the market. In pre-market trading, S&P 500 futures fell 0.12%, Nasdaq futures fell 1.00% and Dow futures rose 0.42%. Check out this morning's top movers from around Wall Street,.
