AT&T’s beleaguered stock has gotten an upgrade from sell to neutral from MoffettNathanson analyst Craig Moffett. The Wall Street veteran’s reasoning, though, offers little reassurance to investors who may be worried about the company’s massive debt and strategic direction. The company’s shares “have fallen so far and so fast, with such a dramatic divergence from Verizon, that it simply no longer warrants maintaining a sell rating,” Moffett writes.
