Comcast's (CMCSA) earnings this quarter will be driven by high speed data growth and business services, according to Tuna Amobi, Equity Analyst at S&P Capital IQ. Amobi also expects to see strength from Comcast's entertainment division. Comcast will report third-quarter results early Tuesday. Amobi said Comcast has been fairly aggressive in trying to keep consumers who want to ditch their cable connections for other services, like Netflix (NFLX) and Hulu. 'They just recently launched their own streaming package for broadband subscribers,' said Amobi. 'They've been pretty aggressive on the authentication side, trying to roll out content to a variety of platforms. That said, that's something the industry as a whole is grappling with.' Amobi sees cord cutters as a longer term risk factor for Comcast. In the short term, Amobi is concerned with advertising weakness and will watch for commentary around that in the earnings report.
