Query: The best stock investing book I've ever read

The Five Rules for Successful Stock Investing has recently replaced Buffettology as the best stock investing book I have ever read. Morningstar.com is always a great source of investing advice, and they have produced a very informative book.Other titles I highly recommend:The New Buffettology by Mary Buffett (Stocks)A Random Walk Down Wall Street by Burton G. Malkiel (Mutual Funds)The Theory of Investment Value by John Burr Williams (Stocks & Bonds)
