I started stock trading only several months ago when I was forced to learn how after inheriting an IRA full of stocks. I am in the health field and had never traded a stock in my life and did not even know what bid vs. ask was when I started. I found that the "Dummies" books were excellent, VERY basic for the beginner. They cover charting, trading strategies, brokerages, fundamental analysis, exchanges, taxes- but in basic beginner fashion. I have to admit I STILL refer back to sections occasionally and have found that the more I have learned, the more information I get each time I re-read them.
DAY TRADING FOR DUMMIES (excellent)
STOCK INVESTING FOR DUMMIES (excellent)
FUTURES AND OPTIONS FOR DUMMIES (I don't trade these yet, but found it is very important to understand how these also effect your stock price when a headline comes out stating "large short volume" or high put vs. call volume)
ECONOMICS FOR DUMMIES (really helps you anticipate and understand how economic news will impact your stock price, because it is all more intertwined than you think).
I have also moved on to "The intelligent investor" by graham. Also VERY good, though some parts are dated. This is the basic strategy that Warren Buffet learned while working with Mr. Graham.
I continue to read and will post more books that I have found helpful. I also credit this site for helping me learn and practice before I began trading my real stock. I started the last game one month before it was over (in March) and worked my way to the top 100 players- so I believe in the basics that these books have taught me.
THanks again to this site! I tell everyone I know about it! Good luck to all.
