GRNB vs SDSI

GRNBAVanEck Green Bond ETF

SDSIBAmerican Century Short Duration Strategic 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%.

SDSI Active short-duration credit in an ETF wrapper. Managers roam investment-grade and high-yield corporates, government paper and securitized debt, US and overseas, chasing income while keeping rate sensitivity short.

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.

SDSI The fund seeks current income and, secondarily, long-term capital appreciation. It uses active bond selection and tactical sector management across U.S. and non-U.S. markets.

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.

• SDSI Short by design. It measures itself against the Bloomberg U.S. 1-3 Year Government/Credit index, so it carries far less rate sensitivity than the intermediate aggregate funds that define this category.americancentury.com
• Go-anywhere toolkit: investment-grade and high-yield corporates, Treasuries and agency paper, mortgage- and asset-backed bonds, US and non-US, spread across roughly 400 positions.americancentury.com
• 0.32% a year undercuts the median fund in its bond cohort, unusual for active management, and holdings are disclosed daily rather than quarterly.americancentury.com
• Income is the stated first objective, with capital appreciation second, and the fund's policy is to pay distributions monthly.

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%.

• SDSI Cheap for active, pricey next to index. BND, SCHZ and SPAB each charge 0.03%, so the managers' sector calls carry the whole burden of justifying the gap.
• The high-yield sleeve is where the extra income comes from, and it is also where credit stress shows up first. This is not a Treasury-only short bond fund.americancentury.com
• It trades lightly compared with the index heavyweights in its cohort, which tends to mean wider spreads. Limit orders matter more here than with a mega-fund.
