Evaluate a noob's Investopedia portfolio and ideas please?

Some small stocks I like that fit this approach are CREE and PRAA. Both are leaders in industries that I expect to grow very rapidly in the next decade (LEDs and debt collection, respectively), and still have low PEs despite this growth potential.

PRAA's up 8% today on news that it closed a favorable credit deal to expand its purchases of consumer debt. It's still a good buy.
