How this list is built

Return on invested capital is operating profit after tax over the debt and equity the company employs, computed from its newest filed statements. The screen: companies listed on Korea Exchange, graded A or B for the quality of what they report; a median daily traded value of at least 250,000 US dollars over 90 sessions, stated in each listing's own currency, so a company nobody can trade is never on the list; and no positive price to earnings under 1, which no real company earns, and no close sitting the whole of its own 52-week high below that high, which no listing that still trades can do. 421 companies passed tonight. Each market is ranked on its own and never added to another. Figures as recomputed on 2026-11-07.
