Terry Smith: Buy Good Companies, Don't Overpay, Then Do Nothing

Terry Smith is the founder of the UK's Fundsmith and is often called "Britain's Warren Buffett." He compressed his entire investment philosophy into three rules—so plain they sound almost trite, yet they have underpinned an outstanding long-term record: buy good companies, don't overpay, and then do nothing.

1. Buy Good Companies: Focus on Return on Capital

The metric Smith relies on most to identify a "good business" is a high and stable return on capital employed (ROCE/ROIC). A business that can generate high returns on relatively little capital and reinvest its profits efficiently is, by itself, a compounding machine. He favors industries such as consumer staples and healthcare, where demand is steady and disruption is hard.

“Our strategy can be summed up in three sentences: buy good companies, don't overpay, and do nothing.”— Terry Smith

2. Don't Overpay: Even Great Companies Can Be Bought Too Dear

Smith never dismisses the importance of valuation—however good the business, an excessive entry price mortgages future returns. But he equally rejects "buying mediocre companies just because they are cheap." The sensible approach is to identify a handful of exceptional businesses within your circle of competence and wait patiently for a price that isn't absurd.

3. Do Nothing: Low Turnover Is an Edge

This is the hardest rule to follow. Fundsmith's turnover is extremely low, because Smith believes that frequent trading manufactures costs, taxes, and opportunities to err, whereas genuinely good businesses should be held for the long term so that the growth in their intrinsic value works for you. "Doing nothing" is not laziness—it is respect for compounding.

How This Maps to Our Engine

Smith's three rules are almost a portrait of this platform's workflow: use the engine to identify a "good business at a reasonable price" (both the quality and the price dimensions), save it as a locked card, then perform low-frequency maintenance through "data refresh" and only "revalue" when the long-term assumptions have truly changed—turning "do nothing" into a disciplined process.
