Why Is AT&T Inc. $T Stock Down -9.97% Today? (Find out why any stock moved today on Tickeron.) • $T shares tumbled roughly 9.97% intraday, falling to about $22.39 from a prior close of $24.87. • The primary catalyst was a sector-wide selloff after SpaceX disclosed a deal to acquire nationwide low-band spectrum, intensifying fears of new wireless competition. • Secondary pressure came from the stock trading ex-dividend, analyst price-target reductions, and elevated Treasury yields weighing on income-oriented telecom names. • Peers VZ and TMUS also fell sharply, confirming the decline was an industry-wide reaction rather than an AT&T-specific operational problem. • Broader indexes advanced on the day, underscoring that the weakness was concentrated in the telecommunications sector. • Traders are now watching AT&T's upcoming earnings report, scheduled for late October, for management's response to the SpaceX threat. $VZ $TMUS $CMCSA $LUMN $CHTR $VOD $SATS
