Strategy #0000000110 · Sustainable finance and rating disagreement
ESG ratings and provider disagreement
Enter three provider scores, a disagreement threshold, assumed basket returns and costs.
ESG rating disagreement can reflect differences in scope, indicator weights, sources and estimation methods rather than simply different views of sustainability performance. Research tests links with returns, risk and investor preferences, but results vary by sample, scales and sector. Separate average rating from disagreement and harmonise scales before comparison.
No ratings vendor, emissions data or fund holdings are connected; disagreement does not indicate better or worse ESG performance.
Three ways in
Understand the story. Then inspect the risk.
Start with a familiar situation, check the payoff, then test how the numbers change.

The mechanics · payoff and exposure
Dispersion=\sqrt{\frac{1}{J}\sum_j(ESG_j-\overline{ESG})^2}
Provider scores must share a common scale; returns are manual scenarios and disagreement is not a quality score.

| Conservative version | Higher threshold | Raise signal/sample thresholds and reduce exposure. | May reduce eligible names. |
| Validation version | Out-of-sample review | Freeze definitions before time-ordered evaluation. | Needs clean, representative data. |
