US chip rally lifts TSMC ADR 6.3%, Taiwan stocks eye rebound Monday

US chip stocks rebounded strongly on Friday, with TSMC ADR surging 6.33%, boosting Taiwan stock index futures by 646 points and setting up a potential rebound for Taiwan's market on Monday. The Philadelphia Semiconductor Index jumped 4.21%, led by AMD soaring 11.04% and Nvidia rising 2.78%. TSMC ADR closed at $375.56, a 15.27% premium. However, the Dow fell 0.46%, and concerns remain over Democratic control of Congress potentially tightening AI regulation and rising Treasury yields. Taiwan's weighted index plunged 4.51% last Friday to 39,701.64, with foreign investors selling NT$91.19 billion. Foreign futures net short positions remain near 100,000 contracts, while margin financing dropped NT$42.36 billion, suggesting volatility persists despite the rebound momentum.
