The review of the State Street fund was undertaken at the request of a sub-committee of the investment committee, to address a petition from a student group, Students for Justice in Palestine. The investment committee's decision, however, was based on the consultant's finding that the State Street fund included 100-plus companies engaged in multiple violations of the college's investment policy; the decision expressly did not pertain to a political movement or single out businesses active in a specific region or country.
As such, Hampshire as not explicitly divested from companies doing business with Isreal. Press releases from student organisations should perhaps be confirmed with the involved institutions - in this case Hampshire College - for confirmation.
If I get further information, I will of course add it on.
