On CAPS, 96% of the 113 members who have rated Southern Union believe the stock will outperform the S&P 500 going forward. These bulls include AGCAPS and All-Star BSHumphreyII, who is ranked in the top 15% of our community.

Just last month, AGCAPS summed up the Southern Union bull case with six simple words: "good balance sheet and cash flow."

In a pitch from one week earlier, BSHumphreyII also urged Fools to gas up for the long haul:

Of all the industries out there, natural gas production is the one I have the most confidence in for the next several years. There are plenty of reasons to be bullish on energy, even in the middle of global economic trouble. I'm particularly bullish on gas, which has been lagging behind oil even though there seems to be at least as many reasons to think demand for gas will increase going forward.

Priced near book value and with a strong dividend, Southern Union is priced very attractively right now. I can't think of many reasons not to buy a bargain-priced, financially-healthy company in the natural gas business right now.
