GRNB vs SDFI

GRNBAVanEck Green Bond ETF

SDFIBAB Short Duration Income ETF

In short

GRNB Its peer group is stacked with total-bond-market giants. GRNB goes narrow instead: only dollar-denominated green bonds funding environmental projects, issued worldwide by governments, supranationals and companies. A 2017-vintage specialist at 0.20%.

SDFI A converted mutual fund, not an index clone: AB's bond team roams corporate, securitized and government debt while keeping duration on a short leash. It costs less than the typical fund in its cohort and pays monthly.

Stated mandate

GRNB The fund seeks to track the S&P Green Bond U.S. Dollar Select Index before fees and expenses. The index covers U.S.-dollar-denominated green bonds financing environmentally friendly projects and issued globally by supranational, government, and corporate entities.

SDFI The fund is actively managed and invests across multiple bond sectors with a short-duration focus. It seeks attractive income while aiming to maximize risk-adjusted returns.

Why people hold it

• GRNB The mandate is the point: bonds whose proceeds fund environmentally friendly projects, tracked to the S&P Green Bond U.S. Dollar Select Index instead of a generic aggregate benchmark.vaneck.com
• 0.20% a year runs below the typical fund in its category, and it sits in the top quartile of a large aggregate-bond peer group on how closely it tracks and what it holds.
• Global sourcing, dollar pricing: supranational, government and corporate issuers, roughly 500 bonds, all USD-denominated, so no currency translation layered on top.
• Distributions land monthly, and the fund has been running since 2017.

• SDFI Active multi-sector mandate: managers pick across corporate, securitized and government bonds instead of copying one index.prnewswire.com
• At 0.30% a year, it sits below the median fee in its bond cohort.
• Average duration typically stays under three years, so rate swings move its price less than a core aggregate bond portfolio.alliancebernstein.comaaii.com
• Pays monthly, spread across roughly 600 bond positions.

Worth knowing

• GRNB Thinly traded next to core bond giants like BND, so spreads and order type matter more here.
• Green describes what the proceeds fund, not an issuer's whole business; the credit still sits with governments, supranationals and companies.
• The screen costs extra: plain aggregate rivals like BND and SPAB list expense ratios near 0.03%.

• SDFI You pay for the active call. Index anchors in the same cohort (BND, SPAB, SCHZ) charge 0.03%.
• Thinly traded and modest in size, so spreads can run wider than the category's volume leaders.
• Listed in June 2024 as a mutual fund conversion, so the ETF-era track record is short.prnewswire.com
