In addition to our standard rating service, GMI subscribers also receive a lengthy bibliography of nearly 200 studies examining the link between corporate governance and portfolio returns. Some studies are issue-specific (e.g., the impact of poison pills on stock price performance); others, like GMI's own studies, look at the impact of corporate governance across a large number of variables over a multi-year period.
