About this ETF
The Janus Henderson Mortgage-Backed Securities ETF (JMBS) is designed to achieve its investment goals by concentrating its holdings primarily in debt securities linked to mortgages. Typically, under ordinary market circumstances, the fund dedicates a substantial portion—at least 80%, and often nearly all—of its total investable capital (which includes any funds borrowed for investment purposes) to a diverse portfolio of mortgage-backed fixed-income instruments, spanning a variety of maturity dates. Furthermore, the fund has the option to employ derivatives as part of its strategy.

Guided help: AUM is fund size. The expense ratio is the yearly cost baked into returns. NAV is the value of what the fund owns per share; the market price can sit slightly above (premium) or below (discount) it. Total return assumes distributions were reinvested. Every dataset shows its own as-of date because holdings, assets and quotes update on different schedules.
