I'm going to take a chance here and re-up Navios Maritime. But I'm not alone. Here's how CAPS All-Star floridabuilder put it last month:

[Navios Maritime] is part of the Transportation Ship industry group. This industry group has been in the top 10 rankings for 15 of the past 52 weeks ranking it 8th most powerful industry group. However, 13 of those 15 weeks in the top 10 are dropping off. Those 13 weeks are from May 4, 2007 through Aug 3, 2007. The shippers really broke out early last year and the question is whether or not the weakness since August is permanent or a chance to load up. I believe it is the latter.

His peers agree. Of the last 150 ratings of Navios at CAPS -- all made since late March -- only two investors say the stock will underperform. What's more, of the last 75 to rate Navios "outperform," 16 -- or 21% -- of those rank in the top 5% in the CAPS database.

All of them are looking smart today. Last Tuesday, The Baltic Dry Index, which measures the pricing power of shippers such as Navios, surged by 274 points. Weekly rates for Capesize ships, huge tankers that comprise more than a third of Navios' fleet of owned vessels, improved by 10%. Both gains should add buoyancy to Navios' profits.

But that's my take. What's yours? Would you buy Navios Maritime at today's prices? Let us know what you think by signing up for CAPS today. It's 100% free to participate.
