Pivotal Research analyst Brian Wieser upgraded Discovery (DISCA) to Buy from Hold in light of the stock's recent weakness following its deal to acquire Scripps Networks (SNI). While the "advantages of this combination should not be overstated," Wieser expects that a combined company may perform slightly better in the national TV upfront markets and he notes the guidance for $350M in annual cost synergies after 2019. Wieser keeps a $28 price target on Discovery shares, which have declined about 9.5% since July 31, the day the company confirmed its deal to buy Scripps.
