Just as the title implies, investopedia.com is an encylopedia of investing. It includes an investor's dictionary, tutorials, simulators and free tools. In fact the entire site is free.
This is the website that taught me the majority of what I know. By the time I finally reached my college investing classes, I already knew most of what they taught.
For those who may be considering financial services careers, investopedia also includes free exam prep and practice tests for almost every exam.
All in all, investopedia.com is a great website with loads of free, accurate information. If you want to learn how to invest, or simply want to know what a piker trader is, investopedia is an excellent resource.
