While other companies may make you smarter, happier, or richer, we aim to do all three by providing outstanding business and investing advice — with a decidedly Foolish bent. Our name is in homage to the one character in Shakespearean literature — the court jester — who could speak the truth to the king and queen without having his or her head lopped off.

We believe in treating every dollar as an investment in the future you want to create. We believe that investing in great businesses, for the long term, is the most effective path to wealth. We believe in the power of a community to learn and grow together. We believe in keeping score and being transparent in our investment performance.
