The index is reviewed quarterly each February. SPGM employs a sampling strategy wherein it is not required to purchase all of the securities represented in the index. Instead, it holds a portfolio that will represent the same risk and return characteristics of the index. Prior to Sep. 23, 2019, the fund traded under the ticker ACIM.
