In this edition of The Motley Fool's "Ask a Fool" series, Motley Fool One analyst Jason Moser takes a question from a Fool reader who asks: "On Monday, Dec. 9th, the new American Airlines will be issuing stock to its employees. What are my options?" Jason talks about what the bankruptcy process means for shareholders, why the company might use preferred convertible shares, and why diversification can be a Foolish investor's best friend.
