Here is the article. 

  1. Never forget that diversity reduces adversity. Don't just buy stocks — buy stocks, bonds, and other investments classes. Within each category, diversify further. And don't just buy one stock — buy mutual funds of many stocks. (Malkiel makes his case with the stark example of a 58-year-old Enron employee who had a $2.5 million 401k — of Enron stock. When Enron went bust, the employee not only lost her job, but her retirement savings vanished completely.) Finally, the author recommends “diversification over time” — making investments at regular intervals using dollar-cost averaging.
  2. Pay yourself, not the piper. Interest and fees are drags on your wealth. “Paying off credit card debt is the best investment you will ever make.” Avoid expensive mutual funds. “The only factor reliably linked to future mutual fund performance is the expense ratio charged by the fund.” In fact, the author advises that costs matter for all financial products.
  3. Bow to the wisdom of the market. “No one can time the market,” Malkiel says. It's too unpredictable. Professional money managers can't beat the market, financial magazines can't beat the market — nobody can beat the market on a regular basis. The best way to earn consistent gains is to invest in broad-based index funds. It's boring, but it works.
  4. Back proven winners. After Malkiel has preached the virtues of index funds, presumably converting the reader to his religion, he spends a chapter suggesting possible index funds and asset allocations.
  5. Don't be your own worst enemy. Malkiel concludes by admonishing readers to stay the course, warning them against faulty thinking. He discusses the sort of money mistakes I've mentioned before: overconfidence, herd behavior, loss aversion, and the sunk-cost fallacy.
Ultimately, Malkiel's advice can be stated in a few short sentences: Eliminate debt. Establish an emergency fund. Begin making regular investments to a diversified portfolio of index funds. Be patient. But the simplicity of his message does not detract from its value. The Random Walk Guide to Investing is an excellent book because it sticks to the basics:
  • It's short.
  • It's written in plain English — there's no jargon.
  • It's easy to understand — concepts are simplified so the average person can grasp them.
  • It's filled with great advice.
This book refers often to other books to bolster its arguments, and includes quotes from financial professionals like John Bogle and Warren Buffett. Though the advice may seem elementary, it's advice that works. If you want to invest but don't know where to start, pick up The Random Walk Guide to Investing at your local library.
