There are a million reasons to start an investment club. Some people do it with their children, so that they learn about saving. Others find that putting their minds together with friends helps them make better decisions. It reduces the stress of investing and helps them focus.

It doesn't matter whether you're a Wall Street shark or you still hold a passbook savings account; pooling wisdom and resources gives your portfolio more power. Many people find that the payoff is big.

Most importantly, people join investment clubs because it's fun.
