EWY provides unbiased exposure to the Korean equity market with significant exposure to Samsung. The fund tracks an index that ignores most small- and micro-cap stocks. To ensure diversification, the index applies certain investment limits with no single issuer exceeding 25% of the Underlying Index weight, and all issuers with a weight above 5% not cumulatively exceeding 50%. These limits are imposed on regulated investment companies (RICs) under the current US Internal Revenue Code. The index is rebalanced quarterly to coincide with the reporting requirements of RIC-compliant funds.
