What are the two key reasons given for high kurtosis that cannot be overcome with normalization?

Kurtosis measures how heavily the tails of a distribution are, meaning how often extreme outcomes occur. Normalization aims to adjust data so comparisons aren’t distorted by factors like scale or predictable external influences, but it can’t remove tail risk that’s built into the business itself or the regulatory framework. The two factors that produce high kurtosis in a way normalization can’t fix are inherent financial or operational characteristics and regulatory mandates. Financial or operational characteristics—such as concentrated revenue streams, high leverage, asset-intensive operations, or exposure to volatile inputs—create extreme outcomes that persist regardless of normalization. Regulatory mandates—like required capital reserves, compliance costs, penalties, or mandatory disclosures—impose structural constraints and fixed costs that can generate tail events beyond what normalization can adjust for. Weather patterns and geopolitical risk are external shocks that normalization can sometimes account for or adjust away in analyses. Corporate governance and tax policy influence sustainability metrics as well, but the most persistent, unnormalized tail risk comes from the firm’s internal financial/operational structure and the regulatory environment.
