On April 29, 2023, four of the largest technology companies in the United States, including Alphabet, Microsoft, Amazon, and Meta Platforms, are set to announce their earnings for the January-March quarter. This day is significant as it coincides with the release of earnings from approximately 269 companies. These tech giants have been pivotal in the recent stock market rally, and their performance could influence future market momentum. Analysts expect that these companies will collectively invest about $600 billion in artificial intelligence (AI) this year, which has raised concerns about cash flow despite supporting stock prices. Revenue growth projections indicate that Alphabet's sales will rise 18.7% to $107.06 billion, Amazon's will increase 13.9% to $177.30 billion, and Microsoft's will grow 16.2% to $81.39 billion. Notably, Meta is anticipated to achieve the strongest growth, with revenues expected to jump 31% to $55.45 billion, marking its fastest growth in over four years. Ahead of the earnings announcements, stock prices exhibited a mixed trend, while Wall Street's major indexes opened lower. Additionally, the Federal Reserve is expected to keep the federal funds rate steady at 3.50%-3.75%, with market focus shifting to the tone of Chair Jerome Powell's statements.
