Decoding RaymondsIndex: CEI Explained — When Capital Stops Working

Two regulatory events this week frame today's deep dive better than any hypothetical could.

On July 1, Korea's strengthened delisting rules took effect. Market-cap floors rose to 30 billion won for KOSPI and 20 billion won for KOSDAQ (rising again in January 2027). A new penny-stock rule puts companies trading below 1,000 won for 30 consecutive sessions on the watchlist. And full capital impairment now triggers delisting review at the half-year mark — regulators no longer wait for the annual report.

Meanwhile in Washington, the House took up an NDAA amendment that would bar major defense contractors — companies drawing more than half their revenue from Pentagon contracts — from buying back their own stock. The Senate Armed Services Committee adopted an even broader version covering dividends and other capital distributions. The U.S. Chamber of Commerce, the Aerospace Industries Association, and the Business Roundtable urged the House Rules Committee to reject it, calling buybacks a legitimate exercise of board judgment.

Strip away the politics and both stories ask the same question: is capital working for the business, or leaving it?

What CEI measures

The Capital Efficiency Index carries 45% of the RaymondsIndex composite — the joint-heaviest weight, alongside CGI. It combines three families of signals: return on invested capital (is the capital base producing returns?), asset turnover (are assets generating revenue, or sitting idle?), and the investment gap (how much of the capital a company raises actually becomes productive investment?).

A low CEI is not a verdict of fraud. It is a structural signal that capital inside the firm has stopped circulating — assets accumulating without output, raised funds not converting into operations, returns decaying while the balance sheet still looks intact. In relational-risk terms, it is often the first measurable trace of a network that has begun serving insiders rather than the enterprise: investment avoidance, asset diversion, slow-motion extraction.

The Korea parallel

This is why Korea's new half-year impairment rule matters — and why it is not enough. Capital impairment is an endpoint. In RaymondsIndex analysis of 3,109 Korean listed companies, firms that later hit distress events showed capital-efficiency deterioration with an effect size of d>0.8, and the model's leading indicators identified 85.9% of designation events in advance. In 78% of cases, the signal preceded the formal event. By the time full impairment appears in a half-year report, the informed parties have typically already repositioned. The minority shareholder reads it last.

The academic frame

The intuition is not new. Jensen (1986), in his free-cash-flow theory of agency costs, showed that managers controlling cash beyond profitable investment opportunities tend to deploy it in ways that serve insiders rather than owners. More recently, Almeida, Fos, and Kronlund (2016) documented that firms conducting EPS-motivated buybacks reduce employment and investment — direct evidence that shareholder-return optics can crowd out productive capital formation. CEI operationalizes both insights as a continuous, comparable index.

What this means for individual investors

Do not read regulatory tightening as protection. Higher delisting thresholds and half-year impairment checks are lagging filters — they remove companies after capital has stopped working. Your edge is earlier: watch whether ROIC and asset turnover are decaying while headline equity holds up, whether raised capital shows up as CAPEX or as idle financial assets, and whether shareholder returns are expanding precisely as investment contracts. Regulators tighten the exits. Leading indicators tell you who is walking toward them.
