The Little Book of Common Sense Investing

John Bogle literally invented the index fund, so when he writes about investing, you listen. This short book makes an irrefutable case: most investors are better off buying a low-cost, broad market index fund and holding it forever. Bogle backs this up with decades of data showing that actively managed funds consistently underperform their benchmark indices after fees. The math is devastating for the mutual fund industry. For most people, this is the only investing book they'll ever need. Buy an index fund, keep buying it, ignore the noise, and let compound interest do the work.
