SNDU is trading 3.2% down in after-hours trading at $23.55, extending a sector selloff as the 30-year Treasury yield reached a multiyear high.

  • SNDU seeks 200% daily exposure to SanDisk (SNDK), amplifying movement in the underlying stock; its regular-session close was $24.34.
  • SanDisk fell alongside semiconductor and data-storage shares as oil rose on fading U.S.-Iran peace prospects and investors reduced exposure to high-valuation technology stocks.
  • No specific late-breaking SNDU or SanDisk announcement was identified; the decline most likely extends the sector selloff.
