Someone I know trades only penny stocks, and claims to have made fortunes. Think he ended up with half-a-million shares of XYBR acquired near its multi-year-bottom (around 15 cents). His 75K "investment" (if he still holds it) has increased by 1500% or so.
Cheapest stock I ever bought (SCIO) cost 3.75/share and after three years was acquired by JNJ for $45.
If NAG goes to $2 you'll have something to brag about.
