The Zwieg strategy likes the stock's price-to-earnings ratio of 15.1 times, its sales growth, its consistent increases in earnings per share and its total lack of debt. The screen also looks at annual and quarterly earnings acceleration, and indications are that the Apple's revamped products will continue to push that growth at a rapid clip. There might be some concern that the iPad's sales growth will slow down. After all, 73% of American tablet-owners have iPads, according to a Forrester Research survey. Certainly, also, Apple is likely to lose some market share as competitors bring out a bevy of new tablet computers. But the growth in the overall tablet market is likely to keep accelerating as computer users move off laptops and desktops, so iPad sales are likely to remain burning hot for the foreseeable future. Again, that fits nicely into the demands of the Zweig strategy. In short, you do not have to want an iPad or iPhone to want Apple stock -- because plenty of people around the world do want these gizmos.
