BKSE vs SMMD

BKSEABNY Mellon US Small Cap Core Equity ETF

SMMDAiShares Russell 2500 ETF

In short

BKSE Small-cap indexing stripped to 0.04% a year, a fraction of what the typical fund in the category charges. About 600 US small caps, Morningstar's index, and a lot less name recognition than the household tickers.

SMMD Most small-cap funds stop at the Russell 2000. SMMD keeps going, tracking the Russell 2500: that index plus the 500 smallest mid-caps from the Russell 1000. The whole small-to-mid band in one ticker.

Stated mandate

BKSE The fund seeks to mirror the performance of the Morningstar US Small Cap Index. It normally invests nearly all assets in the index’s equity securities.

SMMD The fund tracks the Russell 2500 Index, an index representing small- to mid-capitalization U.S. equities.

Why people hold it

• BKSE A 0.04% expense ratio sits in the cheapest tier of US small-cap index funds, well under iShares' IWM at 0.19% and a hair off Vanguard's VB and Schwab's SCHA at 0.03%.
• Roughly 600 holdings across the Morningstar US Small Cap Index, so no single name drives the fund.
• Straight index mandate: nearly all assets go into the index's own stocks, and it has been one of the tightest-tracking implementations in its peer group.
• Pays distributions quarterly, on the standard schedule for a broad equity index fund.

• SMMD The Russell 2500 is the Russell 2000 plus the 500 smallest mid-caps from the Russell 1000, so you get the small-to-mid handoff without stitching two funds together.lseg.com
• Plain index beta: cap-weighted, reconstituted annually by FTSE Russell, no screens or factor tilts. One mandate since the 2017 launch, and what it holds matches what it says.lseg.com
• 0.15% net of a waiver through July 31, 2027 (0.23% gross), which sits near the category median rather than at the premium end.
• A multi-billion-dollar iShares fund that pays quarterly, so this is a long-standing shelf product rather than a thin niche launch.

Worth knowing

• BKSE Thinly traded and smaller than the category's household names, so bid-ask spreads can be wider and sizeable orders take more care at the screen.
• Launched in 2020, a shorter live record than small-cap funds that have run through several full market cycles.
• Small-cap stocks swing harder than large caps, and this fund holds the index as it comes with no defensive tilt.

• SMMD Cost is the trade-off: the cheapest small-cap index peers charge far less (SCHA and VB at 0.03%), and the fee steps up toward 0.23% if the waiver lapses after July 31, 2027.
• Not a pure small-cap sleeve. Those 500 mid-caps overlap with any mid-cap fund you already own, so the two can double up.lseg.com
• Moderately traded rather than one of the category's volume giants, which can show up as wider spreads on larger orders.
