First Trust Exchange-Traded Fund IV First Trust Commercial Mortgage Opportunities ETF(AMEX:CAAA)

CAAA aims for long-term total return through an actively managed portfolio of AAA-rated commercial mortgage-backed securities. The fund primarily invests in non-agency CMBS, including restricted and interest or principal-only CMBS. The adviser constructs the portfolio using a relative value approach, which utilizes quantitative and qualitative methods to assess each security's risk-versus-reward characteristics against other eligible securities. The fund has no geographical, duration, or maturity restrictions. However, it seeks a weighted average portfolio duration of +/- two years of Bloomberg Non-Agency Investment Grade CMBS: US Aggregate Eligible Aaa Index's weighted average duration. The fund will not invest in CMBS with a credit rating below A-. Lastly, the fund may use derivatives such as futures, forwards, options, and swaps to manage risk, reduce transaction costs, obtain exposure to the CMBS market, manage cash flows, and/or preserve capital.
