On CAPS, 98% of the 749 members who have rated Tsakos believe the stock will outperform the S&P 500 going forward. These bulls include All-Stars BigFatBEAR and JakilaTheHun, both of whom are ranked in the top 1% of our community.

Just three weeks ago, BigFatBEAR remained cautiously optimistic about Tsakos' use of leverage:

With a high yield and lots of profitability, I see only 1 reason to not green-thumb [Tsakos] immediately. … If ROE stays low, then perhaps the large debt would have been a bad gamble. However, I'm predicting ROE will be 20% in coming years, which means that more debt may be a good thing.

In a pitch from one day earlier, JakilaTheHun elaborates. Here's an excerpt:

Earnings and operating cash flows have historically been quite strong. EPS has been in the $4.50 - $5.50 range over the past three fiscal years. While that will probably drop for the current fiscal year, I don't know that it's going to completely fall off a cliff and turn negative, as the share price seems to indicate. …

The only bad thing I can see in their past performance is that Free Cash Flows haven't been overly impressive. This was largely because the entire industry was upgrading capacity during the boom years. We are now at the end of that era and free cash flows should improve in the future. In fact, for FY '08, free cash flows were around $2.25 per share, which definitely isn't bad when you consider the stock's current selling price.
