Governance Matters: The Proof Is in the Proxy

Our research shows a correlation between strong governance and higher stock returns.

Investors have long theorized that companies with poor corporate governance practices may be more prone to mismanagement and weak returns. To investigate further, we’ve looked inward to a key data source: our proxy votes.

Specifically, we draw a correlation example between governance and returns through AllianceBernstein’s (AB’s) proxy-voting track record in recent years. We think proxy voting is one of the most expressive tools investors can use to communicate a view on the quality of a firm’s governance, providing that it’s based on careful analysis and accountability, not a rubber stamp.

Specifically, leveraging proxy voting and direct engagement* with companies can help to improve them, ideally resulting in better long-term outcomes. Several studies, which include our own findings, have made this connection much more apparent.

The Governance-Return Nexus

In one study, professors at Harvard Law School constructed an entrenchment index, or “E-index,” based on six key governance provisions. Their findings linked poorer E-index ratings with reductions in firm value and returns across US equities from 1990 to 2003.

More recently, S&P Global found that, between 2000 and 2017, companies in the bottom quartile of S&P Dow Jones Indices’ Governance Scores underperformed those in the top quintile by about 2% on an annualized basis.

Inspired by these observations and our own experience, we built an internal study to determine if a similar association exists between our proxy-voting record and returns. We found that on average companies for which we voted against management on any number of proposals later underperformed those with which we were more strongly aligned.
