Our read on each fund

ETF.net Research

BKSEABNY Mellon US Small Cap Core Equity ETF

IWMBiShares Russell 2000 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.

IWM The Russell 2000's default trading vehicle. Live since 2000, it packs the small-cap end of the US market into one heavily traded ticker with a deep options market around it. Cheaper funds track the same index; this is the liquid one.

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.

IWM The Fund seeks to track the Russell 2000 Index, which represents small-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.

IWM Roughly 2,000 small US companies in one ticker, weighted by size, no stock picking. iShares has run it since 2000.
The job is to mirror the Russell 2000, and it has tracked that index with very little drift.
Among the most heavily traded funds in US small caps, with a listed options market on top: Cboe options on IWM settle into actual fund shares.cboe.com
0.19% a year, below the median fee in its small-cap index peer group.

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.

IWM VTWO tracks the same Russell 2000 index for 0.06%. The extra you pay here buys trading depth, not different exposure.
Small caps swing harder than the large-cap market, and this fund holds the full index through those swings rather than sidestepping them.
Income shows up quarterly, and small-cap payouts are a side note, not the point of the fund.
