The Philadelphia Semiconductor Index dropped 4.49%, with memory-chip stocks leading the decline.

Micron Technology lost 8.85%, Seagate fell 8.53%, Western Digital dropped 6.91%, AMD and ARM each fell more than 8%, and Intel declined 5.86%. Market participants described the move as a broad rotation out of high-valuation chip names and into more defensive and software stocks ahead of the Federal Reserve's rate decision and a fresh round of Big Tech earnings.
