Would you suggest that a client walk into a courtroom without legal representation? Probably not. The same applies to financial advice. As a financial adviser, I want my clients to use my counsel for any and every financial decision they make. Many people manage their own money, and some even do OK; it depends on the circumstances. I recently came across an interesting article called “The Probability of Success.” In it, the author, William Bernstein, gives an interesting perspective for people who want to manage their own investments. In this article I briefly summarize the four “ingredients” Bernstein suggests the do-it-yourself investor needs to be a successful at managing their own money.
