Investors began the new trading week by seemingly setting aside concerns about an AI bubble, propelling semiconductor stocks higher and driving the Nasdaq Composite Index to a gain of nearly 1%.

Among Monday's top performers were stocks like Micron, SanDisk, and Seagate Technology, which had suffered double-digit percentage declines the previous week.

Meanwhile, oil prices continued to fluctuate between gains and losses. During early trading, Brent crude futures briefly surpassed $90 per barrel as tensions escalated between Washington and Tehran. Prices subsequently gave up those gains after Iran stated it was still pursuing diplomatic channels and had received proposals from mediators, rekindling market hopes for a de-escalation of conflict.

The second-quarter earnings season continues, with companies including Alphabet, Tesla, IBM, and Intel scheduled to report their results in the coming days. Beyond this, the economic data and commentary from Federal Reserve officials are expected to be relatively light this week, as policymakers enter a quiet period ahead of next Wednesday's interest rate decision.
