GGUS is passively managed to provide capped exposure to US large-cap stocks with growth characteristics. The underlying index screens the Russell 1000 for companies with higher I/B/E/S forecasts for medium-term growth and higher sales per share historical growth. The portfolio selection starts by ranking each stocks growth factors and book-to-price ratio (B/P) to produce a composite value score (CVS). Growth stocks are determined based on their CVS and are given proportional index weights. At each quarterly rebalance, regulatory capping targets are applied such that the index caps single issuer weights at 22.5% and the aggregate weight of all companies with weight exceeding 4.5% at 22.5%. The index is monitored daily to ensure that companies with weight greater than 4.8%, in aggregate, are no more than 24%. While GGUS is considered a large-cap fund, it allocates a sizable portion of the portfolio to mid-caps due to its expansive Russell 1000 parent.
