Scuttlebutt
Fisher's own term for research built on informal, real-world conversation — customers, competitors, and suppliers — not official filings alone.
Fisher's own term for a research method built on informal, real-world conversation rather than official documents alone: talking to a company's customers, competitors, suppliers, former employees, and industry specialists to build a picture of a business no single official filing could provide on its own.
The rationale is straightforward: official filings describe what a company wants to disclose, on the schedule it wants to disclose it. Scuttlebutt surfaces things happening in real time that haven't yet, and may never, show up in a formal report — a competitor quietly losing share, a supplier struggling to keep up with a customer's growing demand, a former employee's candid read on management's real priorities.
Fisher considered this method executable by a diligent individual investor, not just professionals with special access — a genuine point of continuity with Lynch's own "invest in what you know" argument covered earlier in this Book Club, even though Fisher wrote decades before Lynch.
A rival firm's salespeople and executives have every incentive to know exactly how a competitor's product actually performs in the field, and relatively little incentive to flatter that competitor when asked directly — making them, somewhat counterintuitively, one of the more reliable sources for an honest read on a company's real strengths and weaknesses.
Unverified rumor, disgruntled-employee bias, or a single anecdote treated as representative are the real risks of this method. Fisher's own practice was to gather many independent sources and look for a consistent pattern across them, not to act on any single conversation alone.
One former employee with an axe to grind describes a company's culture as dysfunctional. On its own, that's a single, potentially biased data point. Only when several independent sources — a customer, a supplier, and a separate former employee with no connection to the first — describe a similar pattern does scuttlebutt actually start to carry real evidentiary weight.
- Scuttlebutt means building a picture of a business from customers, competitors, suppliers, and former employees — not from official filings alone.
- Competitors are often unexpectedly candid, since they have every incentive to know a rival's real strengths and weaknesses and little incentive to flatter them.
- This method surfaces real-time change that hasn't yet, and may never, show up in an official report.
- A single source is an anecdote; a consistent pattern across several independent sources is what actually makes scuttlebutt reliable.
