On CAPS, 97% of the 124 members who have rated TransAlta believe the stock will outperform the S&P 500 going forward.

Earlier this week, one of those bulls, All-Star TMFDeej, tapped the stock as a solid income opportunity:

I don't see any specific catalyst that will lift TransAlta's stock in the short term, but it certainly appears to be oversold to me at this point. ...

The fact that [TransAlta] generates half of its electricity using coal bothers me somewhat, but it is in Canada and not the United States so I don't believe that it will be affected by the new U.S. EPA regulations. I'm sure that Canada has its own regulations restricting coal, but as a fuel source coal is actually really cheap right now, which theoretically should be good for the company. ...

[TransAlta] isn't going to knock your socks off, but it looks like a fairly stable way to generate 6% in a low-yield environment.   

Of course, despite its strong five-star rating, TransAlta may not be your top choice.
