AT&T is trading 5.6% down at $23.50, possibly amid broader risk-off pressure. - Versus the October 8 regular-session close of $24.88. - Reuters reported U.S. stocks edged lower October 8 as soaring oil prices and Treasury yields near multi-year highs stoked inflation concerns; this does not establish the cause. - No company-specific announcement clearly explains the move. AT&T’s October 8 OpenAI collaboration for legal-department AI workflows was not linked to the drop; shares closed higher each prior three sessions.
