Summary
Stock prices fluctuate on a day-to-day basis. Throughout all of this fluctuation, it's important to remember that what you're buying isn't a piece of paper, it's a share of a company. As a shareholder in a company, you're entitled to an equivalent percentage of its profits, expenses, and more. 2008 was a prime example of how investors can overreact, if you invested in 2008 you'd be sitting on >350% gains.
No industry has been punished more recently than oil companies. These undervalued companies have significant potential to reward shareholders. As we'll see throughout this article, ExxonMobil (NYSE: XOM), Gran Tierra Energy (NYSEARCA: GTE), and Occidental Petroleum (NYSE: OXY) are three companies with the ability to generate significant shareholder rewards if you invest today.
