AT&T Stock Eyes Worst Day Since 2000 After SpaceX Deal - AT&T (NYSE:T)
AT&T (NYSE:T) shares fell 11% to $22.14, facing the largest one-day loss in 26 years. The decline follows SpaceX's agreement to buy spectrum licenses, which could compete with AT&T and Verizon (NYSE:VZ). AT&T's CEO downplayed the threat, stating satellite direct-to-cell services address a small market share.
