Apple (AAPL 0.51%) is a product company. At the end of the day, the success of new products will make or break the company. Fortunately, Apple's biggest product business, the iPhone, looks poised for a successful year when it launches later in 2015. But is a blockbuster iPhone 6 launch -- one more successful than even the 5s launch -- priced into the stock today? Fool technology specialist Daniel Sparks doesn't think so.

In the video below, Daniel examines a recent note to investors from Morgan Stanley's longtime Apple analyst Katy Huberty based on her recent visit to Far East Apple suppliers. Based on her conversation with suppliers, Huberty believes suppliers are prepping for iPhone 6 sales to be 20%higher than 5s sales.
