U.S. stock markets are facing a significant test next week with major technology companies set to release earnings reports alongside a Federal Reserve meeting that may mark the end of Jerome Powell's tenure as chair. The benchmark S&P 500 has surged 12% since March 30, while the tech-heavy Nasdaq Composite has gained over 17% during the same period. Investors are optimistic, with 82% of S&P 500 companies exceeding earnings expectations, and overall earnings projected to rise 15.6% in the first quarter. Key reports from tech giants Microsoft, Alphabet, Amazon, Meta Platforms, and Apple are expected to influence market trends. The Fed is anticipated to hold interest rates steady, but rising energy prices due to the ongoing Middle East conflict could temper expectations for future rate cuts. Additionally, the potential confirmation of a new Fed chair adds to the uncertainty surrounding monetary policy. The upcoming week will also include data on U.S. economic growth and inflation, which could further illuminate the impact of the geopolitical situation on the economy.
