What You Know
You know a bit about investing. And if you are like most Americans, it probably goes something like this:
You know you have a investment account, or maybe even more than one. Perhaps a 401(k) started by an employer, or an IRA, or both. You know that saving is good, so you are probably contributing to it regularly. You know that your money is being invested by a firm whose name you probably know and believe to be reputable. And, for the most part, you trust that your money is being managed responsibly, so there will be plenty of funds available when you retire.
