Hypothesizing that advertising, customer support and new feature development costs are relatively high for such firms, he proposes three accounting-based measures of demand-driven risk exposure:

  1. Indirect cost ratio (selling, general and administrative expenses, divided by cost of goods sold plus selling, general and administrative expenses).
  2. Indirect costs-to-net sales ratio.
  3. One minus the direct costs-to-net sales ratio.

He excludes financial, utilities, mining, petroleum refining and pharmaceuticals firms from analysis due to their insulation from consumer demand. Each June, he ranks remaining firms into fifths (quintiles) based on their indirect cost ratios, with the highest quintile most exposed to demand-driven risk.

He further investigates interactions of demand-driven risk with competitive pressure, measuring the latter via textual analysis of Form 10-K submittals to gauge competitor product similarities/sales.
