NIXT tracks an index of recently deleted US small- and mid-cap stocks screened for quality. The portfolio aims to benefit from a potential long-term reversal in the performance of these deleted stocks. The index is constructed from a pool of the top 1000 and top 500 US companies in the RAFI Global Equity Investable Universe (GEIU), which are maintained in two benchmark indices, the Cap-Weight 500 and Cap-Weight 1000.
