EWZS is essentially a bet on the sectors that dominate the Brazillian small-cap market. That being said, it still invests in a variety of different sectors, giving it a broader classification. The index is rebalanced quarterly and uses market capitalization to select and weigh its constituents. The fund uses a representative sampling strategy, which means it will invest in a sample of securities that collectively have an investment profile similar to that of the underlying index. Overall, EWZS is a viable choice for investors who want neutral exposure to the Brazilian small-cap market.
