I have two words that I wish I could hear every day "free education." Aren't those two words just musical? At once they say "won't cost a thing today" and "will help you earn more/be more fulfilled tomorrow." Couple the words "free education" with "investing" and I'm so happy I don't know what to do (other than take a few deep breaths and stop dancing on the chair because it might break).
Well, in a brilliant move, the morningstar company has decided to make my day. They have an incredibly comprehensive and well designed investing classroom that is not only free, but in which you can earn points to more free stuff (like a premium membership = free stock and mutual fund research valued at $100 a year). This is better than free education, it is "paid to learn."
All you have to do is go to the Morningstar Investing Classroom and start taking their bite-sized courses. No previous experience or knowledge of investing is required.
If you're more interested in getting more meal-sized advice, head over to Pathtoinvesting.org for a comprehensive well written investing education by some of the leading professors and practitioners in the field.
Another excellent learn to invest website is Investopedia.com which has articles targeted at beginners, experienced investors, active traders, and retirement. In comparison to MorningStar's curriculum, this is more of an 'a la carte' menu where you can choose individual articles on a topic as opposed to full courses. They also have one of the best investing glossaries i've found anywhere. (Thanks to Loi Tran of Investing Guide for pointing out a glaring omission).
Once you've completed a few sections on the Morningstar and PathtoInvesting sites, you'll be ready to head over to thestreet.com's Apprenticed Investor for beginning investing advice that has more attitude (and less coherence).
MSN Money also has a number of good articles on basic investing and money management, but they are organized in such a convoluted fashion that they are more of a (poorly organized) magazine while these are more textbooks.
