I’ve been with E*Trade for some time now–over a decade, as a matter of fact. One thing about that company, they provide a lot of value add.
In this short posting, I provide a link to some of their free online financial education. Check it out at: http://www.etrade.com/education.
Be advised that because this is their own site, they may illustrate matters using their own product offering–nevertheless, the information can be generalized.
