On CAPS, 97% of the 790 members who have rated Tsakos believe the stock will outperform the S&P 500 going forward. These bulls include All-Star mrindependent, who is ranked in the top 1% of our community, and dumberthanafool.

Just last week, mrindependent informed Fools that Tsakos "is currently profitable and analysts expect continued earnings for 2010 and beyond." Our CAPS All-Star concludes: "At 0.6 times book value, this company looks like a bargain. The company's fleet is newer than most and the company has smart management."

In a pitch from last month, dumberthanafool expands on Tsakos as a slick way to pounce on the Greek tragedy:

This is an oil transport company (with a little LNG capacity as well), based in Greece. They have handled the downturn relatively well. Like all Greek stocks they are getting beaten up because of what's going on with the Greek/euro fiscal crisis. ... [T]hey have a solid current ratio. The dividend is high, almost 4%, but the payout ratio is high. ... Debt/equity ratio is high, but not unmanageable. The company is selling for less than two thirds of its tangible book value as of 2/22/2010, which is an important risk-limiting factor as well.
