IMCB vs SCHM

IMCBAiShares Morningstar Mid-Cap ETF

SCHMASchwab U.S. Mid-Cap ETF

In short

IMCB Mid-cap America for four basis points, running since 2004. It samples Morningstar's US mid-cap index across roughly 400 stocks and hews to that benchmark about as closely as anything in its category.

SCHM The forgotten middle of the US market, for three basis points. SCHM has tracked the Dow Jones U.S. Mid-Cap Total Stock Market Index since 2011, holding roughly 500 companies at a fee nobody in the category undercuts.

Stated mandate

IMCB The Fund seeks to track an index of mid-capitalization U.S. equities. It uses indexing and representative sampling rather than trying to outperform the index.

SCHM The fund seeks to track, before fees and expenses, the total return of the Dow Jones U.S. Mid-Cap Total Stock Market Index.

Why people hold it

• IMCB Costs 0.04% a year, against roughly 0.15% typical for the mid-cap group.
• Indexing, not opinions: representative sampling of the Morningstar US Mid Cap Index, with tracking among the tightest in its peer group.ishares.com
• Trading since 2004 and now a multi-billion-dollar fund, so there is a long operating history here, not a launch-year story.
• About 400 names covering both the growth and value sides of US mid caps, so no style tilt is baked in.

• SCHM 0.03% a year, 30 cents per $100. That ties VO for the lowest fee in the mid-cap group and runs well below the category's typical charge.schwabassetmanagement.com
• Pure index plumbing: no stock picking, no tilts. The fund has tracked its benchmark closely, which is the whole job description here.
• Roughly 500 mid-sized US companies, so no single name carries the fund. Broad enough to be a one-ticket middle slice.
• A multi-billion-dollar fund trading since 2011 and among the stronger builds in its peer group, with active daily volume and tight handling.

Worth knowing

• IMCB Thinly traded next to the category's household names, so spreads and order handling matter more at the moment of a trade.
• All US, all stocks: mid caps move harder than mega caps, and nothing else in the portfolio cushions an equity selloff.
• VO and SCHM cover similar ground at 0.03%, so the cost edge here is over the group average rather than over the cheapest rivals.

• SCHM Mid-caps swing harder than blue chips. This is full, undampened exposure to that middle tier, with nothing built in to soften rough stretches.
• Every provider draws the mid-cap line differently. The Dow Jones index here won't hold the same names as a Russell or Morningstar mid-cap fund, so overlap with what you own varies.
• Distributions land quarterly, and they're a byproduct of the index, not the point. This is a growth-of-capital vehicle, not an income one.
