In the following video, Motley Fool industrials analyst Blake Bos takes a look at the big spike in dry bulk shipping rates recently, up 40% since the beginning of June. Blake tells investors why this isn't as clear cut a story as many are hoping, and that a high dependence on the strong Chinese economy could mean that if there were a Chinese pullback, many of these companies are so debt-laden that they could be in serious trouble. He looks at one company in this space that could be a conservative and less-risky play, but continues to tell investors why this space, as a whole, is a bit too frightening for him at the moment.
