US stock futures edged higher on Tuesday as investors prepared for a busy day of corporate earnings that could shed light on how companies are managing heightened geopolitical risks. Notable firms set to report later today include UPS, General Motors, Coca-Cola, Visa, and Starbucks. Market participants also kept a close eye on diplomatic developments in the US–Iran standoff after Tehran submitted a new proposal to Washington. US officials remain skeptical of the offer and are expected to issue counterproposals in the coming days, with Iran’s nuclear program still a key sticking point. In after-hours trading, Bed Bath & Beyond and Lending Club surged more than 26% and 12%, respectively, after posting stronger-than-expected first-quarter results. In Monday’s regular session, the S&P 500 and Nasdaq Composite gained 0.12% and 0.2%, respectively, both notching new record highs, while the Dow dipped 0.13%.
