AdvisorShares Pure US Cannabis ETF (MSOS) is an actively managed exchange-traded fund that provides dedicated exposure to U.S. cannabis and hemp companies, including multi-state operators (MSOs), through investments in domestic equity securities and total return swap contracts. Launched on September 1, 2020, and listed on NYSE Arca, MSOS targets long-term capital appreciation by focusing on companies spanning agriculture, biotechnology, pharmaceuticals, real estate, retail, finance, and medical cannabis applications; its portfolio emphasizes dominant market players with profitability and growth potential, including top holdings such as Curaleaf Holdings (28.37%), Trulieve Cannabis (22.30%), and Green Thumb Industries (17.63%). The fund, managed by Dan Ahrens of AdvisorShares Investments LLC—a Bethesda, Maryland-based firm founded in 2006—trades with options available and maintains assets under management exceeding $1.3 billion as of December 2025. MSOS operates exclusively within U.S. markets, serving investors seeking thematic access to the world's largest cannabis market amid evolving state-level legalization and federal regulatory developments.
Recent portfolio adjustments include the integration of the February 2025 merger between Cansortium Inc. and RIV Capital into FLUENT Corp., reflecting ongoing sector consolidation and active management to optimize exposure to high-potential operators. In Q2 2025, MSOS reported a net asset value decline of -8.90% amid stalled federal reform progress, prompting continued concentration in top MSOs comprising over 80% of holdings, while November 2024 saw a name change for its related leveraged product from AdvisorShares MSOS 2x Daily ETF to MSOS Daily Leveraged ETF (MSOX). The ETF has navigated 2025 surges tied to cannabis rescheduling discussions under President Trump, with shares rising over 50% in a single day in December amid reform optimism, alongside sector trends like Cresco Labs' California exit and TerrAscend's financing. No major new funding rounds, acquisitions, or launches directly involving MSOS occurred in the past 1-2 years, though AdvisorShares maintains complementary cannabis products like YOLO (global focus) and MSOX (leveraged U.S. exposure).
