🟢 AT&T is trading 5% up in pre-market — no company-specific catalyst reported

AT&T is trading 4.95% up at $20.35, from the August 31 close of $19.39; no company-specific announcement was found on September 1, 2026 explaining the move.

• Investor calendar lists upcoming conference appearances on September 9–10 and third-quarter earnings for October 21.
• Broader market is modestly weaker, so it does not clearly explain the opposite-direction move.
• With no reported catalyst or volume data, the pre-market gain may reflect limited liquidity in this long-dated debt security.
