IHY is a passively managed ETF that tracks an index of high-yield corporate bonds from countries outside of the US. To qualify for the index, securities should be issued by any non-US corporation from around the world that are denominated in euros, US dollars, Canadian dollars, or pound sterling in the major domestic or Eurobond markets. The fund uses a sampling method in tracking the index, which means it will invest in a sample of securities that collectively have an investment profile similar to that of the underlying index. The index is market-value-weighted and capped at 3%.
