Analyst Report

This ETF offers targeted exposure to mortgage-backed pass-through securities issued by GNMA, a unique corner of the domestic fixed income market that has had its shares of ups and downs over the years. The GNMA portfolio will generally consist of bonds with strong credit ratings, though history has taught investors that these ratings are not always worth all that much. GNMA focuses on types of bonds that are often included in broad-based bond funds such as AGG or BND, so this fund might not be all that useful for those building a long-term portfolio (since it is a bit targeted). But it can certainly be very useful as a tactical tool for establishing exposure to this segment in the market for those who believe it offers superior risk adjusted returns or is poised for a period of strong performance.

GNMA tends to be tilted towards the long end of the duration spectrum, so investors will be taking on a fair amount of interest rate risk along with some moderate credit risk with this investment. There are a handful of other ETFs in the Mortgage Backed Securities ETFdb Category; investors would be wise to compare the risk and return characteristics of these products before establishing a position.
