Best books/source to learn about investing?
gcv: For the shortest introduction to sensible, index-based investing, read The Coffeehouse Investor (Bill Schultheis). It shouldn't take more than an hour or two to go through, and it contains all the basics. Then, if you're interested in a more in-depth analysis of the same thing, read A Random Walk Down Wall Street (Burton Malkiel), as suggested by several others in this thread.
