What it's about

Malkiel argues that stock prices move unpredictably, incorporating new information so quickly that neither technical chart-reading nor fundamental stock-picking can reliably beat a broad market index over time. Drawing on decades of academic finance research, he shows that professional fund managers rarely outperform the market after fees, and he recommends low-cost index funds as the rational response. First published in 1973, the book helped popularize the efficient-market hypothesis for general readers and fueled the rise of index investing.
