Where to start learning about investments? One good website that I would recommend to start off would be http://www.investopedia.com. The website has lots of articles on investing, finance, etc.
Some books that I would recommend would be:
The Neatest Little Guide to Stock Market Investing by Jason Kelly
One Up on Wall Street by Peter Lynch
Buffettology by Mary Buffett and David Clark
The Five Rules for Successful Stock Investing by Pat Dorsey
F Wall Street by Joe Ponzio (this book has a very interesting title)
