That's the same two that jumped out at me for some reason. I went with PRGN because they had more cash and slightly lower p/e. They both might be smaller than some of the others but they are profitable and that's good. I also liked PRGN because they plan to almost double in the next year or so. I read that the price of used ships is probably coming down because of over supply. I guess that's good for a company that buys used ships. I expect resistance to reduce now that the company has finished selling shares to raise capital.
Good luck on both your picks. I'm still not too good at diversifing like I should.
