Rebuilt every trading night.\n SMRF bid-ask spread and liquidity\n IQ Liquidity Score\n Not scored, 0 of 6 measured.\n A fixed 0 to 100 scale of trading conditions, the same anchors for every fund; 100 is the easiest to trade. It measures how cheaply and reliably the fund can be bought and sold, not whether to own it. How the score is built \n Cost to trade Not measured: the issuer's 30-day median spread is not read for this fund Capacity Holdings can absorb up to $91m a day; part of the book has no volume figure Price fidelity Not measured: no closing premium is held for this fund Primary market Not measured: it first traded on 2026-02-19, and no N-CEN ETF row for series S000101442 is in the quarters read (2024q4 to 2026q3) Bad-day behaviour Not measured: no daily closing premium is held for this fund Depth Not measured: needs trade and quote data (Phase 2) \n Capacity\n Its holdings can absorb up to $91m a day, measured on its own holdings, as of Oct 22, 2026. The holding that sets the limit is Terrestrial Energy Inc (IMSR), 0.57% of the fund.\n How to trade SMRF\n When ETF spreads are usually widest in the first minutes after the open and the last minutes before the close. ETFIQ measures this fund\u2019s own day once it has trade data. Size Part of its book has no volume figure, so the room for a large order is an upper bound. Coming with trade data\n Spread through the day, buyers against sellers, an estimate of retail flow, large trades and the closing auction\u2019s share, each once ETFIQ has trade and quote data.\n Questions people ask\n Who is the LMM for SMRF? SMRF\u2019s lead market maker (LMM) on NYSE Arca is GTS Securities LLC. Lead market maker per NYSE Arca, as of Oct 23, 2026. Sources and dates\n Capacity: ETFIQ, from each holding\u2019s 20-day median dollar volume, to Oct 22, 2026.\n Where to next\n SMRF fund page ETF trading costs and liquidity Limit orders vs market orders for ETFs Why low volume does not mean illiquid How the IQ Liquidity Score is built Compare SMRF with another fund The score measures trading conditions, not the fund.
