Rebuilt every trading night.\n MBSX 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 Not measured: its holdings are bonds, which have no volume source here Price fidelity Not measured: no closing premium is held for this fund Primary market Not measured: it first traded on 2025-05-01, and no N-CEN ETF row for series S000091134 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 Not measured: its holdings are bonds, which have no volume source here.\n How to trade MBSX\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. 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 Sources and dates\n Where to next\n MBSX 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 MBSX with another fund The score measures trading conditions, not the fund.
