ARM Holdings is trading 8.24% down at ARS 14920.00 amid a broad semiconductor sell-off.

  • Rising bond yields are pressuring high-growth technology valuations as the 30-year Treasury yield reaches multi-year highs.
  • Escalating U.S.-Iran tensions and higher oil prices are reinforcing risk-off sentiment; the Philadelphia Semiconductor Index is down 3.7%.
  • No clear ARM-specific announcement was identified for August 18, 2026; the move appears sector-driven.
