SEMI.AX is trading at A$36.00, up 3.09%, reflecting a broad semiconductor rebound that strengthened through September 18, 2026.
- U.S. chip leaders including Intel, AMD, Micron, NVIDIA, and Broadcom advanced sharply; the Philadelphia Semiconductor Index gained about 3.1%.
- Easing Treasury yields, softer oil prices, and renewed optimism about artificial-intelligence chip demand supported the sector.
- The move appears sector-driven rather than specific to SEMI.AX, with no separate fund-level catalyst identified for September 21, 2026.
