May 12 - U.S. stock index futures edged down on Tuesday as the recent surge in chip stocks lost momentum and hopes for a quick diplomatic resolution to the Middle East conflict dimmed. Market participants are also awaiting a high-profile consumer inflation print that could provide fresh guidance on the path for interest rates.

All three main U.S. stock indexes had climbed on Monday, with the S&P 500 and the Nasdaq registering fresh record closing highs, driven in part by continued enthusiasm around artificial intelligence and overall corporate results.
That AI-linked enthusiasm cooled on Tuesday, with much of the semiconductor sector trading lower in premarket activity. Separately, telehealth company Hims & Hers Health shares plunged 14.6% after the firm missed Wall Street estimates for first-quarter revenue and reported an unexpected loss.
With crude oil prices rallying, markets are parsing the implications for inflation and central bank policy, while upcoming economic reports will be watched for further signs of price momentum and consumer demand.
