US Stock Information Active List | Most of the Mag7 fell back, with Meta leading the decline by over 11%, and third-quarter tax expenses causing profits to plummet by 80%

On Thursday, the top traded stock in the U.S. market, Meta Platforms, fell over 11%, with a trading volume of $58.938 billion. Despite the company's strong revenue performance in the third quarter, it also forecasted a significant increase in operating expenses and capital expenditures for 2026, and plans to accrue a large one-time tax expense. The latest disclosed financial report shows that the company achieved revenue of $51.24 billion in the third quarter, a year-on-year increase of 26%, but net profit plummeted 83% year-on-year to $2.71 billion, with earnings per share of $1.05, far below the market expectation of $6.68. The core reason for Meta's "cliff-like" drop in earnings is the $15.93 billion one-time non-cash income tax expense resulting from the "One Big Beautiful Bill Act" introduced by U.S. President Trump, which directly raised the company's effective tax rate from 12% in the same period last year to 87%. Additionally, Meta's total costs and expenses in the third quarter were $30.7 billion, a year-on-year increase of 32%, significantly outpacing the 26% revenue growth rate, leading to a contraction in operating profit margin from 43% to 40%. Nvidia, ranked 4th, fell 2%, with a trading volume of $36.328 billion, and its market value dropped below $5 trillion. Driven by the explosive demand for AI chips and new collaborations in supercomputing, 6G, and robotics, Nvidia became the first company to stabilize its market value at the $5 trillion mark yesterday. Tesla, ranked 5th, fell nearly 5%, with a trading volume of $32.214 billion
