Pali Research upgraded the Mediacom‘s stock to ‘neutral’ from ‘sell,’ and also posited an interest by Mediacom to acquire the remaining assets of Insight. Pali said that despite the MSO’s slower growth prospects and weaker clustering relative to its peers, "we are increasingly hard pressed to find a major catalyst that will drive down MCCC shares." — Pali Research raised its ’08 estimates for Discovery Holdings and increased its price target on Discovery shares to $28.50 from $25.50. It cited tangible improvement in ad sales because of ratings strength and reductions in retail/education costs (think the closing of all branded retail posts). "Discovery is one of the few cable network companies that can truly exploit their content globally without having to create significant amounts of local programming," said Pali in a research note.
