Interpreting Congruence & Possible Reasons for Voting Alignment
Interpreting Congruence: Why High Alignment Is Not Proof of Causation
- In a paper by Robert Matthews in 2000 titled“Storks Deliver Babies (p=0.008)”, the Stork-Baby Correlation was examined.
- The examined data showed that a highly statistically significant correlation exists between stork populations & human birth rates across Europe.
- As the author notes, this “shows that a highly statistically significant correlation exists between stork populations and human birth rates across Europe. While storks may not deliver babies, unthinking interpretation of correlation and p-values can certainly deliver unreliable conclusions.”
Possible Reasons for Voting Alignment with Proxy Advisory
Shared Best Practices: Both investors and proxy advisors frequently operate from the same global governance ‘playbooks.’ Frameworks established by organizations such as the ICGN, UN PRI, and the OECD, alongside national Corporate Governance Codes (such as the DCGK in Germany), create a standardized baseline for high-quality governance. Consequently, high alignment might reflect a shared adherence.
Routine Consensus: A certain portion of AGM agendas consist of «routine» or non-controversial items, such as dividend payments or the appointment of auditors. In these cases, there is a natural market-wide overlap in voting, which mathematically inflates alignment percentages.
Feedback Loops: ISS and Glass Lewis conduct comprehensive annual policy surveys and regular client consultations to ensure their benchmarks remain aligned. By incorporating this direct input into the guidelines, proxy advisors adopt a form of consensus views.
Non-Glass Lewis Clients: The high level of alignment observed among ISS-exclusive clients with Glass Lewis recommendations might indicate that proxy advisors are not necessarily standard-setters, but act as mirrors of an existing basic market consensus.
Methodology
- Our study examines 15 of the largest international institutional investors, selected based on average investment size and strategic shareholder structures.
- For the 2025 FTSE 100 Annual General Meeting (AGM) season, we analysed voting recommendations from leading proxy advisors ISS and Glass Lewis.
- To ensure a consistent baseline for voting guidelines and investor expectations, we excluded companies without full proxy coverage -typically due to insufficient free floats.
- Consequently, this report focuses on 85 FTSE 100 companies, cross-referencing their proxy recommendations against the actual voting records of our 15 selected investors.
