NISM Certifications · NISM-Series-XV: Research Analyst · Industry Analysis

A research analyst compares two cement companies. Company A has a four-firm concentration ratio for its industry of 80% and Company B's industry has a ratio of 30%. Which conclusion is best supported when analysing pricing power and margin stability?

The better supported conclusion is that the industry with the 80% four-firm concentration ratio is likely to show greater pricing discipline. Few dominant players find it easier to avoid price wars, although demand cycles and regulation can still hurt margins.

  1. ACompany B's industry is likely an oligopoly with greater pricing discipline
  2. BCompany A's industry is likely to have greater pricing discipline, though regulation and demand cyclicality can still affect marginsCorrect
  3. CConcentration ratios have no link to pricing behaviour
  4. DCompany B's industry must have higher barriers to entry than Company A's

Explanation

A high four-firm ratio suggests an oligopolistic structure where few players can coordinate or follow price moves, supporting pricing discipline. It does not guarantee margins, since cyclicality and regulation matter. Option A reverses the inference, and D cannot be concluded from concentration alone.
