Barclays analyst Kannan Venkateshwar downgraded Discovery Communications (DISCA) to Equal Weight saying comments at the company's investor day imply operating leverage is going to take longer to kick in than expected. Further, the stock trades at a premium to most other names in the space, including 21st Century Fox (FOX), which benefits from a "strong international story," Venkateshwar tells investors in a research note. He cut his price target for Discovery shares to $30 from $34. The owner of Animal Plant and other TV stations closed yesterday up 51c to $28.86.
