US stocks were mixed on Monday, with the Dow, S&P 500, and Nasdaq moving unevenly as investors looked ahead to a major week for corporate earnings. The market appeared to be searching for its next clear driver, especially around enthusiasm for artificial intelligence and how much support it can continue to provide for technology shares.

Chip stocks were a key focus during the session. Semiconductor names initially helped lift sentiment, but some of those gains faded as traders turned cautious before upcoming results from major technology companies. The earnings reports are being watched closely for signs of how strongly AI demand is still feeding into revenue expectations and broader market momentum.

Energy markets also added to the uncertainty. Oil prices were volatile after briefly touching $90 a barrel, with geopolitical tensions contributing to sharp moves. Those swings kept investors alert to the possibility that higher energy costs could complicate the broader outlook for inflation, consumer spending, and corporate margins.

With few immediate catalysts outside earnings, Wall Street remained in a holding pattern. That left markets balancing optimism around AI and chip-related growth against concerns about volatility in oil and the risk of disappointment from Big Tech results later in the week.
