Tesla shares fell in premarket trading as the company lowered prices of its Model 3 and Y vehicles in the U.S. The price cuts are expected to lead to a reduction in the 2024 earnings per share estimate for Tesla. The company's third-quarter deliveries trailed expectations due to factory shutdowns. Analysts suggest that Tesla's strategy is to sell EVs at no profit in anticipation of a high-margin revenue stream from the sale of full self-driving software.
