Research firm Needham & Co. has made a major hike to its price target for Apple stock, adjusting the number from $280 to $375. Analyst Charlie Wolf notes that the increase is based on the many changes since a February evaluation. In particular the vector of Mac and iPad sales is thought to be "materially higher" than originally forecast; iPad sales, for example, were at one point expected to hit 20 million by 2019, but are already approaching 12 million a year. This is before the iPad has even finished spreading to other countries, says Wolf.
