MINO vs MUB

MINOBPIMCO Municipal Income Opportunities Active Exchange-Traded Fund

MUBAiShares National Muni Bond ETF

In short

MINO An actively run muni fund from PIMCO's credit desk: federally tax-free income hunted across the whole ratings ladder, with room for up to 30% junk munis. Most big muni ETFs simply track an index. This one shops.

MUB Municipal bonds, indexed and cheap. Since 2007, MUB has packaged investment-grade national munis into tax-exempt monthly income for five basis points a year, and it sits among the deepest pools in the muni-ETF aisle.

Stated mandate

MINO The Fund seeks current income exempt from federal income tax and long-term capital appreciation.

MUB The fund seeks to track an index of investment-grade U.S. municipal bonds, providing diversified exposure to the national municipal-bond market and tax-exempt income.

Why people hold it

• MINO Prospectus allows up to 30% of total assets in below-investment-grade munis, so managers can buy bonds index funds screen out. Roughly 240 positions do the work.yahoo.com
• Built for tax-aware income: the stated objective is current income exempt from federal income tax plus long-term capital appreciation, and distributions land monthly.pimco.com
• Active credit picking with a leash: portfolio duration normally stays within two years either side of the Bloomberg Municipal Bond Index.yahoo.com
• The portfolio has stayed tightly aligned with the muni mandate in its filings, and it sits in the upper half of its municipal-bond peer group.

• MUB 0.05% a year against a muni-ETF median near 0.30%. In a category built on modest, tax-exempt yields, that fee gap is real money left in the fund.
• The benchmark is AMT-free: the ICE AMT-Free US National Municipal Index screens out munis whose interest can be pulled into the alternative minimum tax.ishares.com
• Tracks its index closely, one of the tighter jobs in its peer group, and distributes monthly. A multi-billion-dollar fund that trades actively.
• Broad investment-grade exposure across the national muni market, spread over thousands of issuers rather than one state's budget.ishares.com

Worth knowing

• MINO At 0.49% a year it costs well above the muni cohort median of 0.30%, and many multiples of index staples like VTEB (0.03%) and MUB (0.05%).
• High-yield munis can be thinly traded and carry real default risk. That is the trade-off behind the extra income this mandate reaches for.yahoo.com
• A mid-size fund with moderate trading activity, so spreads can run wider than the category's busiest names.

• MUB Two rivals undercut it: VTEB and SCMB both run 0.03%. A two-basis-point gap is small, but it is a gap.
• A bond fund with no maturity date to hold to. Share prices move with interest rates and muni credit conditions, both directions.
• National by design, so no single-state tilt and no in-state tax angle. iShares runs state-specific muni funds such as NYF for that job.
