YLD is a truly active ETF because the fund's portfolio manager has broad leeway to invest across asset classes and geographic boundaries in search of income, unlike active ETPs with index based strategies. The portfolio manager vaguely provided selection criteria for eligible securities such as economic factors, credit spreads, investor sentiment, and momentum. The portfolio may hold global equities of all sizes and styles, including REITs and MLPs. The fixed income component may include corporate and sovereign debt, investment-grade and high-yield debt, convertibles, preferred stock, mortgage securities, and floating-rate instruments. The manager faces no exposure limits of any kind, other than those mandated by RIC compliance.
