In this edition of The Motley Fool's "Ask a Fool" series, Motley Fool One analyst Jason Moser and Motley Fool Stock Advisor analyst Brendan Mathews take a question from a reader who asks: "I do not have a huge trading account, so I am looking for penny stocks to swing trade. Does anyone on the Motley Fool trade penny stocks?"

In response, Brendan points out the huge hazards with penny stocks. Most micro-cap penny stock companies shouldn't even be public: If their promise was equal to their promotion, they'd be funded by management or smart venture capitalists. Unfortunately, most penny stocks exist exclusively to dupe investors. With penny stocks, it's very important to tread with caution -- or avoid them altogether.
