Citigroup analyst Richard Gardner has upgraded Apple to buy from hold, reports MarketWatch, citing several “meaningful product catalysts and expectations of significant gross market upside due to declines in flash memory and DRAM pricing.” Apple’s 12-month price target remains at US$105. “The stock was last up 1.7% at $84.70 in pre-open trading. As of Friday’s close of $83.27, the stock had lost 15% since reaching an all-time high of $97.80 on Jan. 10.”
