About this ETF
SMBS offers representative exposure to US mortgage pass-through securities. The index consists of fixed-rate, investment grade, agency mortgage-backed securities guaranteed by Ginnie Mae, Fannie Mae, and Freddie Mac. The index construction starts by initially grouping individual to-be-announced (TBA) deliverable mortgage-backed securities into pool aggregates based on program, coupon, and vintage. These pool aggregates must have a minimum of $1 billion currently outstanding and a weighted average maturity of at least 1 year to be included in the index. The index constituents are market value-weighted and reconstituted on the last business day of each month.

Latest News for SMBS
No articles mention this fund directly in the last 7 days; showing general ETF coverage.
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.
