I'd start even simpler than a lot of these other comments. I've worked in the investment space for years and there are many, many great books to read. In fact, there are just too many of them. Start of with a book by Peter Lynch - Probably "One up Wall Street". He's a legendary investor. After that, go a bit more broad - "A Random Walk Down Wall Street". After you're done with that, try learning about fundamental and technical analysis. They are 2 very different things, but are the basis for valuation/pricing. When you're done with that, you'll know more than most.
