The most 'undervalued' stocks in Portugal

As opposed to overbought, oversold means that a company's stock price has decreased substantially. Now this can be for a number of reasons, but the most common one is that there's been a major sell off on the back of bad news. Often this is because there are legitimate concerns about the business' fundamentals, but other times the overselling is the result of a storm in a teacup or other non-event and the price will eventually rebound. Discerning the difference between the two scenarios takes patience and research though, which is exactly why you're on this page.
