Exxon, the biggest investor-owned energy company in the world, predicted in December that oil will continue to be the most important source of energy. That's because cars, trucks, airplanes, trains and ships will still depend heavily on oil-derived fuels such as gasoline and diesel.
This year, investors seem unforgiving with Apple, looking for perfection and punishing the stock for anything less. The company's stock price slipped below $500 for the first time last week, as investors saw signs that the iPhone 5 was falling behind competition from phones running Google's Android software, especially those from Samsung Electronics Co.
The latest quarterly report added to the concerns. Apple warned that its revenue growth, which had been running at a speed more reminiscent of promising startups than multi-national corporations, is slowing down considerably.
A big reason: It has been nearly three years since a new product has come from a company still seen as the embodiment of innovation. That last product, the iPad, came in 2010, when its CEO Steve Jobs was still alive. Some analysts question whether Apple can keep growing by just releasing new versions of its old products. The long-rumored Apple TV, is still just that, a rumor.
