About this ETF
MARS targets pure-play companies worldwide involved in the space economy and its enabling technologies. Such companies derive at least 50% of their revenue from activities such as the development, manufacturing, or operation of rocket launch systems, spacecraft and satellites, space-related defense systems, and communications infrastructure. This also includes supporting technologies such as network infrastructure, AI services, software and IT services, semiconductor production, and advanced military technology. The adviser constructs the portfolio using a proprietary thematic-relevance methodology that analyzes company disclosures, financial reports, and industry research to assess each companys connection to the growth of the commercial space economy. The strategy is based on the belief that significant growth opportunities exist in space infrastructure as it becomes increasingly integrated into global economic systems. The fund rebalances its holdings at least quarterly.

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.
