A Random Walk Down Wall Street: The Time-Tested Strategy for Successful Investing

by Burton G. Malkiel

it’s probably a good idea to explain what I mean by “investing” and how I distinguish this activity from “speculating.” I view investing as a method of purchasing assets to gain profit in the form of reasonably predictable income (dividends, interest, or rentals) and/or appreciation over the long term. It is the definition of the time period for the investment return and the predictability of the returns that often distinguish an investment from a speculation. A speculator buys stocks hoping for a short-term gain over the next days or weeks. An investor buys stocks likely to produce a dependable future stream of cash returns and capital gains when measured over years or decades.
