The Time-Tested Strategy for Successful Investing

Burton Malkiel's enduring classic makes a provocative argument: a blindfolded monkey throwing darts at a newspaper's financial pages could select a portfolio that would do just as well as one carefully selected by experts. His case for index investing — rooted in the efficient market hypothesis — changed how millions of people invest.

First published in 1973 and updated through twelve editions, A Random Walk democratized investing by showing that ordinary investors don't need expensive fund managers. Malkiel's central argument — that stock prices are essentially random and unpredictable in the short term — challenged the entire active fund management industry.
