Adtran shares should be bought on weakness, says Stephens

Stephens believes that Adtran's (ADTN) stock sold off yesterday partly because investors thought that it is a major competitor of Acme Packet (APKT), which was acquired by Oracle (ORCL). However, Stephens reports that there is no major overlap between the companies, and it thinks Adtran's shares can jump about 30% in 2013.
