I've always liked periodically going out to find stocks that I've never heard of. This has become a more and more difficult exercise over time as my knowledge of stocks out there has increased faster than the issuance of new securities, but it is always important to find new answers to the same question "What should I buy now?".
As part of this exercise, I endeavor to find five stocks that are worth buying that I have never heard of. I encourage readers to do the same as you often stumble across new and exciting prospects. For example, I found MICC during a concerted effort to find African related stocks. Of course, you also run into a lot of crap that isn't worth buying, but that's the fun of it.
Anyway, I have found the best way of doing this is to look within the industry lists of stocks that are in sectors you like. Look down the list for the smaller companies and go from there. Think of it like a Wikipedia adventure where you just keep clicking on the links.
By Sunday, I hope to have found my five. Good hunting!
