CDW is trading 5.4% up at $140.80 after no clear company-specific catalyst was identified for August 21, 2026.

  • The latest major announcement was August 5 earnings, when revenue and adjusted EPS beat estimates, but margin pressure weighed on shares.
  • Broader markets are modestly higher pre-market, though the S&P 500 and Dow gains are below the threshold for a strong market-wide explanation, and CDW’s move remains unclear.
