Quality Investing

Cunningham, Eide and Hargreaves, working from the investment approach of AKO Capital, set out what makes a business high quality and therefore worth owning for long periods at prices that do not look cheap on conventional value measures.

Their framework has three components. Strong predictable cash generation, meaning the business converts profits to cash reliably without heavy reinvestment requirements. Sustained high returns on capital, which indicates a competitive advantage that has survived competitive attack. And attractive growth opportunities, meaning the business can reinvest at those returns rather than being forced to distribute.

The substance of the book is the set of patterns they identify as producing these characteristics. They cover recurring revenue models, businesses selling small-ticket items whose cost is trivial relative to the customer's total spending and whose failure would be expensive, companies with pricing power derived from brand or from switching costs, businesses benefiting from friendly middlemen who prefer to sell their product, toll roads and regulated monopolies, businesses with low penetration in a growing category, and corporate cultures that produce consistent operational improvement.

They also cover what destroys quality, including acquisitions outside the core, changes in ownership or management, technological change, and regulatory action.

The book is written from a manager's approach and the evidence is illustrative rather than statistical. Quality as a factor has an empirical basis in the academic literature, which the authors reference lightly. The main risk the book underweights is that quality businesses can be identified correctly and still produce poor returns because the quality is already in the price.

Corporate-governance scholar and longtime George Washington University law professor; edits The Essays of Warren Buffett and writes on Berkshire and quality investing.

The Essays of Warren Buffett reorganises decades of Berkshire shareholder letters by subject - governance, accounting, mergers, valuation - turning scattered annual commentary into a usable manual. The later books extend the analysis to Berkshire's decentralised structure and to the traits that make a business durable enough to hold for decades.
