U.S. stock markets are experiencing notable gains as hopes for a potential U.S.-Iran peace deal continue to buoy investor sentiment. The S&P 500 and Nasdaq indices have risen to new record highs, with the Dow also hitting an all-time high. Reports suggest that negotiators have made progress on extending the Iran ceasefire, which has instilled optimism among traders despite some lingering caution due to ongoing geopolitical tensions. Oil prices have fluctuated, with recent declines following reports of a potential breakthrough in negotiations. Major tech stocks, including Micron and others, are contributing significantly to this upward momentum. However, investors remain vigilant, weighing the implications of continued unrest in the region.
