I honestly don't like his write up at all. His main argument is "it used to sell for a lot more and I'm counting on a reversion to THAT price". Thats a bad argument for a stock that formerly traded at ridiculous valuations.

It may dominate its market. He could be right, but I want to see analyst projections (and current) EBITDAs and such. Actual hard metrics that back up a stock valuation. I'll post a write up from one of my favorite authors as an example and BOLD out some things you have to know to make a sound investment.
