US stocks dip as oil tops $100 amid Iran conflict and peace talk doubts

US stock markets fell with the S&P 500, Dow, and Nasdaq retreating after recent gains, driven by rising oil prices and uncertainty over US-Iran peace talks. Oil surged above $100 per barrel, boosting energy stocks as the only sector gaining this month. Investor sentiment turned cautious due to conflicting signals about peace negotiations and ongoing Middle East tensions, including potential US troop deployment. The market outlook remains bearish until clear progress in talks emerges, with oil prices closely watched for their impact on inflation and economic growth.
