SIZEAiShares MSCI USA Size Factor ETF

SUSAAiShares ESG Optimized MSCI USA 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.

SUSA One of the original US ESG funds, running since 2005. Its index is sector-neutral, so the screening happens inside each sector instead of turning into one giant bet against energy.

Stated mandate

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

SUSA The fund seeks to track a sector-neutral index of U.S. large- and mid-cap companies with positive aggregate ESG ratings and extensive screens for controversial activities.

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

SUSA Sector-neutral construction: sector weights stay near the broad US market, so the ESG work shows up in which companies are held, not in a lopsided tilt away from energy or utilities.ishares.com
Trading since January 2005, one of the longest-running ESG equity ETFs in the US, and today a multi-billion-dollar fund rather than a launch-week experiment.
0.25% a year undercuts the typical fund in its factor peer group, and the portfolio hews closely to the MSCI USA Extended ESG Select Index it advertises.
Large- and mid-cap US names, roughly 190 of them, with cash paid out quarterly. A core-shaped equity sleeve, not a thematic sliver.

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.

SUSA Cheaper peers sit on the same shelf: Xtrackers' USCA at 0.07% and iShares' own SIZE at 0.15%. The extended controversy screens and long history are what the extra costs buy.
It trades lightly next to mega-cap index funds, so spreads can widen in fast markets. Limit orders are the standard fix.
Screens for controversial activities keep some familiar large caps out, so results can drift from a plain US market index in either direction.
