IIGD vs SPBO

IIGDAInvesco Investment Grade Defensive ETF

SPBOAState Street SPDR Portfolio Corporate Bond ETF

In short

IIGD Most investment-grade corporate funds just buy the whole market. IIGD screens it first: higher-quality issuers, shorter maturities, roughly 160 bonds, 0.13% a year. A defensive tilt inside the calmer corner of credit.

SPBO The whole investment-grade corporate bond market in one ticker for three basis points. Most rivals sell you a maturity slice; SPBO owns the lot, and it undercuts other funds tracking the very same Bloomberg index.

Stated mandate

IIGD The Fund seeks exposure to U.S. investment-grade bonds with relatively higher credit quality and shorter maturities, using representative sampling of its underlying index.

SPBO The fund seeks investment results that generally correspond, before fees and expenses, to the price and yield performance of the Bloomberg U.S. Corporate Bond Index.

Why people hold it

• IIGD Defensive by design. The index targets U.S. investment-grade bonds with relatively higher credit quality and shorter maturities, so you hold a screened slice rather than the whole corporate market.invesco.com
• 0.13% a year undercuts the typical investment-grade corporate ETF, which is unusual for a rules-based screen rather than a plain market-cap index.
• Roughly 160 bonds, sampled to follow the index closely, with cash paid out monthly. On measured tracking and portfolio build it sits in the upper half of its investment-grade corporate peer group.

• SPBO 0.03% a year against a category median of 0.19%. In bond land, where the yield does the heavy lifting, that fee gap is not a rounding error.
• Thousands of corporate bonds across the full maturity range, so you hold the broad IG corporate market instead of one duration bucket.ssga.com
• Same index, very different tolls: KORP charges 0.29%, JLQD 0.35%, JHCB 0.53%. SPBO sits at the cheap end of that list.
• Running since 2011, pays monthly, and tracks its benchmark about as closely as anything in the investment-grade corporate group.

Worth knowing

• IIGD The screen cuts both ways: shorter maturities and higher-rated issuers mean less interest-rate and credit risk than a broad corporate index, and less of the extra yield that comes with them.
• Small and thinly traded next to the category giants. Spreads can be wider than headline funds, so limit orders matter, and modest assets are worth watching in any niche fund.
• Cheap for what it does, but not the floor: the big broad corporate index funds (VCIT, USIG, SPIB, IGIB) charge a few basis points for whole-market exposure.

• SPBO Full maturity range means long-dated paper is in the mix, so the price moves more when rates move than short-maturity peers like IGSB or SPIB.
• Corporate credit only. No Treasuries or mortgages to lean on, so the fund rides the health of corporate borrowers as well as the rate cycle.ssga.com
• Investment grade by design, US issuers only. No high-yield or emerging-market bonds in the basket.
