Julie Stav is ready to share her hands-on techniques with the world. You don't have to be a mathematician or money expert, she explains -- all you need is your initial investment (no matter how small) and a sound grasp of basic principles that can help you pick winners, recognize opportunities, and ditch the duds before they drain your funds. In addition to guidance on getting started, she offers tips on finding (or founding) an investment club -- a support system that can give you a major advantage in the market.
