Amazon and Intel shares fell sharply in premarket trading on Friday after both companies reported disappointing September quarter results. Amazon's third-quarter revenue and profit were below expectations, and it recorded negative free cash flow for the second consecutive quarter, yet maintained its capital expenditure forecast of $220 billion for 2026. Investors are concerned about the tech giant's massive AI spending and the prospects for its returns. Affected by this, Nasdaq futures fell 2%, and Google shares also closed down 13% on Thursday.
