DISK is trading 3.11% down at $36.65, amid weakness across memory and storage shares.

  • Reuters reported that higher oil prices and Treasury yields weighed on risk assets; pre-market context also pointed to broader market pressure.
  • Memory-chip peers Samsung and Micron fell 1.3% and 2.1%, respectively. DISK is a memory-focused ETF, and available reporting identified no company-specific catalyst.
