BBMC vs VO

BBMCBJPMorgan BetaBuilders U.S. Mid Cap Equity ETF

VOAVanguard Morningstar Mid-Cap ETF

In short

BBMC J.P. Morgan's no-frills mid-cap sleeve: roughly 500 U.S. mid caps for 0.07% a year, less than half the typical fee in its peer group. No tilts, no theme, just the middle of the market at a discount.

VO The plain middle of the US market for three basis points. VO owns roughly 300 stocks sitting between the 70th and 85th percentile of investable market cap, each at index weight, with buffer bands that slow the churn at the edges.

Stated mandate

BBMC The fund is designed to provide U.S. mid-cap equity exposure through an indexed approach.

VO The fund seeks to track the CRSP US Mid Cap Index by investing in its U.S. mid-cap stocks through passive, full replication.

Why people hold it

• BBMC 0.07% a year against a 0.15% median across its mid-cap cohort. The fee gap is the whole pitch, and it compounds quietly.
• Roughly 500 holdings tracking the Morningstar US Mid Cap Target Market Exposure Extended Index: the broad middle of the U.S. market, not a stockpicker's slice.
• Does one job and stays in its lane. Plain indexed U.S. mid-cap equity, and one of the tightest mandate matches in its peer group.
• Launched in 2020 and already past the billion-dollar mark, with J.P. Morgan's BetaBuilders index lineup behind it.

• VO Costs 0.03% a year against a 0.15% median for mid-cap peers, matching SCHM as the cheapest in the group and undercutting IWR by a wide margin.
• Full replication, not sampling: it holds the index's roughly 300 names at index weight, and its tracking is among the tightest in the mid-cap group.vanguard.com
• Trading since 2004 as a share class of Vanguard's Mid-Cap Index Fund, it has grown into one of the largest and most actively traded mid-cap index funds.sec.gov
• CRSP draws the mid-cap line by percentage of market cap, not a fixed stock count, with buffer zones at the edges so companies migrate gradually rather than jumping buckets.crsp.orgbogleheads.org

Worth knowing

• BBMC Thinly traded next to category giants like VO and SCHM, so bid-ask spreads can run wider, especially in fast-moving markets.
• Cheap, not cheapest: VO and SCHM sit at 0.03% for similar broad mid-cap exposure.
• Pure mid cap, so no mega-cap ballast to steady the ride, and income arrives quarterly rather than monthly.

• VO Mid caps move harder than blue chips, and Vanguard flags that: the fund sits at the top of its own 1-to-5 risk scale.vanguard.com
• One band of the market by design. No mega caps, no small caps, so it covers the middle rather than the whole US market.crsp.org
• About 300 stocks is a narrower net than a total-market fund casts, and sector weights are simply whatever the middle of the market looks like at the time.
