Our read on SIZE
AThe 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.
The fund seeks to track an index of U.S. stocks that have smaller market capitalizations relative to their peers.
Why people hold it
- 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
Worth knowing
- 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.
