Does adopting ESG, diversity, and sustainability language affect NZX stock performance?
Important: Correlation, Not Causation
This analysis examines whether companies that use certain language in annual reports have different stock returns. It does not prove that language causes returns. Larger, better-resourced companies tend to use more ESG/sustainability language and tend to outperform — these may be driven by the same underlying factors (size, management quality, sector) rather than the language itself. All results should be interpreted with this confound in mind.
Data sources: Buzzword data is extracted from NZX company announcements (annual reports, market updates) via keyword pattern matching — the same data underlying our Corporate Language Tracker. Stock prices are year-end closing prices from NZX.
Term classification: We classify 16 terms into 4 categories: Green/Climate (8 terms), Social Justice (4), Cultural/Te Ao Māori (3), and ESG Framework (1). A company is an “adopter” of a term if it appeared in their announcements by the specified year.
Returns: Calculated as simple price returns using year-end closing prices. Dividends are not included, which may disadvantage income-focused stocks (utilities, REITs) that are also heavy woke-language users.
