Tesla disclosed in its latest earnings report that fourth-quarter 2023 revenue declined 3% year-over-year to $24.9 billion, yet operating profit reached $1.41 billion with a gross margin of 20.1%—both exceeding market expectations. Meanwhile, CEO Elon Musk announced the company will officially discontinue the Model S and Model X, reallocating their production lines to manufacture the Optimus humanoid robot. This strategic shift underscores Tesla’s further pivot toward future technologies. Separately, Microsoft’s concurrently released earnings showed a slowdown in cloud business growth during its second fiscal quarter, drawing market attention. Investors are closely watching Tesla’s transformation and the subsequent performance of U.S. tech stocks.
