Comcast’s efforts to build up its coffers has some investors worried that the nation’s largest cable operator may be looking to buy a large content company similar to its failed bid to buy the Walt Disney Co. five years ago.

According to a Reuters story, the names being bandied about for a possible purchase include MTV Networks, Paramount Film Studio or Time Warner, even though analysts said there was little evidence of any actual talks.

Whether Comcast is hunting a media content company or not, the perception that it is has hurt its stock this year as investors chose to sit on the sidelines until Comcast’s intentions become clear, Reuters said.

The Reuters story cited an interview last week in Broadcasting & Cable with former Disney CEO Michael Eisner, who mentioned Time Warner as a prospective acquisition for Comcast, although Eisner denied having any specific information on a pending deal.
