Abstract: | Using the South African divestment case, this study tests the hypothesis that social pressure affects stock returns. Both short-run (3-, 11-, and 77-day periods) and long-run (13-month periods) tests of stock returns surrounding U.S. corporate announcements of decisions to staf or leave, South Africa were performed. Tests of the impact of institutional portfolio managers to divest stocks of U.S. firms staying in South Africa were also performed. Results indicate there was a negative wealth impact of social pressure: stock prices of firms announcing plans to stay in South Africa fared better relative to stock prices affirms announcing plans to leave. |
