Apple (AAPL - Get Report) shares fell 1.52% to $434.67 as Credit Suisse cut its earnings estimates, citing near-term worries about the iPhone. Analyst Kulbinder Garcha cut his earnings estimates on the company, but kept the "outperform" rating as he believes Apple will refresh its iPhone lineup in the second half of 2013 that will "return Apple to its growing ways." He now expects 30.6 million iPhones to be sold in the second quarter of 2013, due in large part to a mid-2013 iPhone refresh, which may cause some hesitancy on consumers. There are rumors that Apple will release the iPhone 5S sometime around mid-year, though nothing has been confirmed at this point. Activist hedge fund investor David Einhorn also dropped his lawsuit against the company, following a victory in court over a proposal to issue preferred stock.
