In the late 1950s, in his book Common Stocks and Uncommon Profits
, Phil Fisher recommended making investment decisions based on “scuttlebutt,” the kind of information an investor could get by asking around. This entailed tracking down and interrogating customers and competitors, employees, and former employees. Doing research, in the sense of gathering evidence and analyzing it to reach a conclusion, was hard work, but enabled analysts committed to such intellectual labor to obtain an edge over their competitors simply by having better, and more complete, information.
Indeed, when I started my career in investing in the late 1970s, obtaining even basic financial info about a German car company still required going to Germany and knocking on the company’s door.
Now gathering information no longer takes much effort. We are deluged by floods of data—not only the details of prices, volumes, margins, and capital investments of individual companies, but also highly granular data about credit card receipts, numbers of cars in parking lots, or words used in media reports. These new, “alternative” sources of information have briefly given some stock pickers a slight edge in predicting short-term stock price movements. The informational advantage provided by such data is but fleeting, however; once this data is commercially accessible to everyone, the advantage disappears. Thus, even for the short-term investor, information gathering itself no longer provides a lasting edge.
For long-term investors, the relationship to information has changed even more fundamentally. You no longer need to seek information; it finds you. Your job, rather, is to act as what Lou Gerstner, the former CEO of IBM, called an “intelligent filter”—determining the information that is important and ignoring data that (in the case of the investor) doesn’t help you forecast cash flows and estimate the value of a security.
