U.S. stock index futures rose on January 31, 2025, following a strong earnings report from Apple Inc. (AAPL), which posted Q1 revenue of $124.3 billion and earnings per share (EPS) of $2.40, exceeding market expectations. The positive earnings news contributed to a notable increase in the Nasdaq, which gained over 150 points. Other stocks that saw significant movement included Atlassian (TEAM), which surged on guidance, and Deckers (DECK), which fell despite a revenue boost. Market sentiment was further influenced by investor focus on upcoming inflation data, which is expected to impact Federal Reserve policy decisions. Futures also rose amid concerns regarding potential tariffs from former President Donald Trump, although the market remained buoyed by Apple's performance.
