In an introductory finance course, students are introduced to the concepts of diversification and asset allocation.   We are attempting to create an asset allocation game for students to actively participate during the semester.  Students will be assigned the task of creating an asset allocation based upon their personal risk tolerance for their mock 401k account.   Throughout the semester students will be given a few bits of financial information regarding market conditions during that period.  It is hoped each week will be equivalent to a two- or three-year period, so that during a twelve to fifteen-week period students will experience the ups and downs of a 24 to 45-year period.  Each student will determine how often they wish to rebalance their portfolio based upon either the current market conditions or their predetermined asset allocation rebalancing plan.  The student will not be graded on the performance of their account but on a few short papers the student will write over the semester.   At the end of the semester the student will see how their portfolio would have also performed under several different allocations.  The student will benefit from this assignment with a realistic view of how asset allocation and rebalancing of their account can affect their actual 401k account.
