COST is trading at $955.94 (down 3.9%) as investors lock in profits following a sharp post-earnings reversal despite strong fiscal Q3 results.

  • The company reported fiscal Q3 2026 EPS of $4.93, beating analyst estimates, with net sales increasing 11.6% year-over-year.
  • Results were bolstered by robust e-commerce and membership-fee growth, yet shares extended a multi-day slide while broader indices traded higher.
