A great university, but an even better stock. Why? American Public University System (APUS), wholly owned by American Public Education, Inc. (APEI), makes a strong case for leadership in its segment by providing online programs to address critical challenges in higher education. As America faces the dual challenges of reining in crippling tuition costs while significantly increasing the number of college graduates receiving a quality education, APUS has found a business model that seems to accomplish both goals.
