SIZEAiShares MSCI USA Size Factor ETF

TMFCCMotley Fool 100 Index ETF

In short

SIZE The size factor without leaving the large-cap pool: SIZE holds roughly 500 US stocks and leans toward the smaller names in that universe, spreading weight away from the mega-cap giants. An iShares factor original from 2013.

TMFC The Motley Fool's stock-picking brand, boiled down to one ticker: roughly 100 large US companies held through the firm's own index, rules-based instead of alert-by-alert. The name costs extra.

Stated mandate

SIZE The fund seeks to track an index of U.S. stocks that have smaller market capitalizations relative to their peers.

TMFC The Fund seeks investment results that generally correspond, before fees and expenses, to the total return performance of the Motley Fool 100 Index.

Why people hold it

SIZE Charges 0.15%, roughly half the typical fee among US factor ETFs.
Tracks the MSCI USA Low Size Index tightly, one of the closer index implementations in its peer group.
Roughly 500 holdings, so no single name dominates the way it does in a cap-weighted US index.
Running since 2013, one of the original iShares single-factor funds rather than a recent launch.ishares.com

TMFC Rules-based, not vibes-based. It follows the Motley Fool 100 Index and has stayed close to that benchmark rather than drifting into discretionary picks.
One fund replaces a stack of newsletter alerts: roughly 100 US companies inside a standard 1940 Act ETF, running since its 2018 launch.
It has real scale for a boutique issuer, with over a billion dollars in assets and steady enough volume that entering and exiting is usually uneventful.

Worth knowing

SIZE Thinly traded next to headline index funds, so bid-ask spreads can run wider and bigger orders need more care.
This is a tilt, not a small-cap fund: the index draws from US large and mid caps and favors the smaller end of that pool.
A mid-sized fund by category standards, not one of the asset-gathering giants. Pays quarterly.

TMFC 0.50% a year is the brand tax: roughly double the median for US factor funds, and far above cheap peers like MGV (0.05%) or SIZE (0.15%).
All-US, all-equity, roughly 100 names. That is a shorter list than a total-market fund, so single-stock moves carry more weight.
Cash comes back once or twice a year, not monthly, so it is built around growth in the shares rather than a regular payout rhythm.
