Apple ( AAPL) - Get Report had its price target cut to $156 from $164 a share by a Morgan Stanley analyst who also raised her services revenue estimate for the technology giant. Analyst Katy Huberty said in a research note that the price target cut reflected lower multiples being granted to several of Apple's peers, but maintained her overweight rating. Shares of the Cupertino, Calif. company were up 0.47% to $126.22 in morning trading Tuesday. Huberty also said she was raising her Apple Services revenue forecast to account for accelerating Google TAC-related revenue growth (TAC refers to Traffic Acquisition Cost, or ad revenue-sharing payments to partners). She noted that strong App Store "revenue of 28% in F2Q was in-line with our forecast."
