Several financial analysts have raised their estimates for Apple following the company's second-quarter results. Among these is Canaccord Genuity's Michael Walkley, who has raised his target for Apple stock from $740 to $775. "While our checks indicate slowing iPhone sales ahead of the iPhone 5 launch, we believe very strong international iPhone sales position Apple for very strong sales of an LTE iPhone 5 in the December quarter and beyond to drive strong F2013 earnings growth," he writes in a new memo.
