A Random Walk Down Wall Street by Burton G. Malkiel — book cover

A Random Walk Down Wall Street

Burton G. Malkiel · 1973

Princeton economist Burton Malkiel makes the case that stock prices move so unpredictably that a blindfolded monkey throwing darts at the financial pages could pick a portfolio as good as the experts' and shows why low-cost index funds, not stock-picking or market timing, are the surest path to wealth.

Why it’s on the shelf

Classic argument for passive index investing over stock-picking and market timing.

Three of the ideas you’ll keep

The Clif summary of A Random Walk Down Wall Street pulls out 7 insights. Here are the first three.

  1. Stop trying to beat the market and buy it instead: put the core of your portfolio in low-cost, broad-based index funds that simply track the whole market rather than chasing individual winners.
  2. Start saving early and automatically, because compounding is the real engine of wealth: use the Rule of 72 (divide 72 by your return to find the years it takes money to double) to see how powerful time is.
  3. Use dollar-cost averaging: invest a fixed amount on a fixed schedule so you buy more shares when prices are low and fewer when they're high, removing the temptation to time the market.
