US stock futures showed positive movement as investors reacted to tentative signs of easing tensions in the Middle East, particularly the potential resumption of talks between US and Iranian delegations. This optimism helped lift the S&P 500, which has largely recovered from recent losses related to geopolitical events. The Nasdaq 100 extended its winning streak to nine days, marking its strongest rally since September 2025, driven by robust performance in large-cap technology stocks. Despite these gains, the market remains sensitive to geopolitical developments, including stalled negotiations and maritime restrictions. Airlines such as United and American Airlines experienced gains on speculation of potential deals, contributing to sector-specific movements. However, earnings reports provided mixed signals; while BlackRock saw stronger inflows and profits, JPMorgan and Wells Fargo reported declines, raising questions about whether earnings momentum can withstand ongoing macro volatility.
