Grinnell College’s 18.8 percent investment return is leaving others in the dust -- for now.

The endowment, with a preliminary value of $1.8 billion at June 30, has the top return among at least 20 of the largest college funds that began reporting performance for fiscal 2017. The average increase for endowments and foundations for the 12 months through June was 12.7 percent, according to early data by Cambridge Associates of more than 400 institutions.
