A value stock is traditionally defined in terms of how investors in the marketplace are valuing that company's future growth prospects. Low P/E multiples are good base indicators that the company is undervalued and can most likely be labelled as a value stock.

Below is a list of notable value stocks in the energy sector:

The Significance: A value stock may need some time to rebound from its undervalued position. The risk of investing in a value stock is that this emergence may never materialize.
