JPMorgan Chase Bank NA report:
We believe the release of iPhone 5 could potentially add between 1/4 to 1/2%-point to fourth quarter annualized GDP growth.
Our equity analysts believe around 8 million iPhone 5’s will be sold in the US in Q4, even while sales of previous generation iPhones are maintained at a solid pace. While we have no idea how much these will retail for, if it is similar to previous launches it would be around $600. Likewise, if the imported cost component is similar to previous leading generation phones it would imply around a $200 per phone addition to imports (which is a subtraction from GDP). The difference between these two figures, $400, would represent the trade margins, which figure into GDP.
Thus, calculated using the so-called retail control method, sales of iPhone 5 could boost Q4 GDP by $3.2 billion, or $12.8 billion at an annual rate. This would boost annualized GDP growth in Q4 by 0.33%-point.
