Contrarian investors are always searching for beaten-up stocks that might offer attractive upside potential. In some cases, these companies pay big, sustainable dividends, which can generate attractive yield while investors wait for better days. Let's take a look at Enbridge Inc. ( TSX:ENB )( NYSE:ENB ) and Inter Pipeline Ltd. (TSX:IPL) to see why they might be interesting picks. Enbridge Enbridge is trading at its worst levels of the year after Q3 2017 earnings came in a bit weaker than analysts expected. What happened? Lower revenue from the company's natural gas operations partially offset the benefits realized from the addition of Spectra Energy earlier this year. The company expects Q4 to be better, driven by increased liquids volumes and a full quarter of revenue coming from recently completed projects. As a result, Enbridge is sticking with its 2017 earnings guidance of $3.60-3.90 per share.
