The Canadian energy stocks on our list today are all oil & gas exploration and​ production companies with market capitalizations under $2 billion and revenues exceeding $1 million over the last 12 months. As the industry median for these producers was an EV/S ratio of 4.6x, these 5 companies could be seen as undervalued yet potentially susceptible if the oil price begins to slide.

The Enterprise Value to Sales (EV/S) Ratio is used to measure how much you would pay for a company’s revenue...[and] is seen as a more accurate measure than the Price to Sales Ratio (P/S), as it accounts for the debt in a company’s capital structure, compared to the P/S which only uses market capitalization...and by including debt you get a more holistic picture of the company. If a company has a lower EV/S ratio it is said to be undervalued and a more attractive buy.
