Analysts at Citigroup believe that Apple Inc. still has the potential to rally another 30%, even after recent gains that took the company’s valuation close to $3 trillion. Atif Malik, an analyst at Citigroup, started coverage of Apple with a buy rating and a $240 price target, the highest among Wall Street analysts. Malik believes that the Street is underestimating the potential for continued gross margin expansion at Apple, driven by a shift towards higher-end iPhones and further market share gains in China and India.
