EFIV vs FEUS

EFIVAState Street SPDR S&P 500 ESG ETF

FEUSANorthern Trust ESG & Climate US Large Cap Core ETF

In short

EFIV A screened S&P 500 that still looks like one. EFIV trims to about 300 names on ESG criteria but holds industry-group weights close to the parent index, for 0.10% a year.

FEUS Plenty of ESG large-caps are a screened S&P 500. FEUS instead optimizes the 600 biggest US companies toward higher ESG scores and lower carbon, while holding sector weights near the parent. Fee: 0.09% net of a waiver through March 1, 2027.

Stated mandate

EFIV The Fund seeks to track an index of securities selected using environmental, social, and governance sustainability criteria while retaining industry-group weights broadly similar to the S&P 500 Index.

FEUS The fund seeks results that generally correspond, before fees and expenses, to the price and yield performance of the Northern Trust ESG & Climate US Large Cap Core Index.

Why people hold it

• EFIV Charges 0.10% a year, well under the 0.25% typical of its values-screened peer group.
• Keeps industry-group weights broadly similar to the S&P 500, so the screen changes which names you own more than which sectors.
• Tracks its declared index very tightly, one of the cleaner implementations in its cohort.
• Straightforward 1940 Act index fund from SPDR, running since 2020, distributing quarterly.

• FEUS Not a screen, an optimizer: it starts from the 600 largest US companies, tilts toward higher ESG scores and lower carbon, and caps each name's active weight at -1.00% to +0.75%.sec.govflexshares.com
• The ESG Vector Score follows SASB standards, grading the sustainability issues that are financially material to each industry instead of applying one generic rating.sec.govflexshares.com
• 0.09% net of a waiver through March 1, 2027 (0.10% gross), below the category median. ESGU charges 0.15%, SNPE and EFIV 0.10%; only XVV, at 0.08%, goes lower.
• The portfolio matches the index it advertises, and it sits in the top quartile of a crowded 48-fund ESG peer group.

Worth knowing

• EFIV About 300 stocks, not 500. The screens remove names, so results can diverge from the headline S&P 500.
• Cheaper shelf-mates exist: XVV at 0.08% and ESGV at 0.09% undercut it on fee.
• Mid-size asset base and moderate trading volume, which can mean wider spreads than the mega-cap index giants.

• FEUS Thinly traded and smaller, roughly 130 stocks. Thin volume can mean wider spreads; filings flag new fund risk, where a fund that stays small may track its index less closely.flexshares.com
• Norms-based and controversial-business screens drop some big US names outright, so returns can drift from the broad market in either direction.sec.govflexshares.com
• The FlexShares label became Northern Trust ESG & Climate US Large Cap Core ETF in 2026. Same ticker, same index.flexshares.com
