GXIG vs USIG

GXIGBGlobal X Investment Grade Corporate Bond ETF

USIGAiShares Broad USD Investment Grade Corporate Bond ETF

In short

GXIG An active corporate bond fund that runs a quant multifactor model and a deep neural network across the US investment grade market, then holds a concentrated slate of about 100 bonds instead of shadowing a thousand-name index.

USIG Most investment-grade corporate bond funds hand you one slice of the maturity curve. USIG takes the whole thing, thousands of US dollar corporate bonds from short-dated to long, for four basis points a year.

Stated mandate

GXIG The Fund seeks total return through both income and capital appreciation.

USIG The fund seeks to track an index of U.S. dollar-denominated investment-grade corporate bonds.

Why people hold it

• GXIG At 0.15%, it undercuts the typical fund in its investment grade corporate cohort (0.19% median) while running an active book rather than an index.globalxetfs.com
• Security selection leans on machines: sub-adviser Mirae Asset uses a quantitative multifactor model and a deep neural network to screen the corporate bond universe.globalxetfs.com
• About 100 bonds, not thousands, so manager conviction actually shows up in the portfolio. Income is paid monthly.
• Buying individual corporate bonds is clunky for retail accounts. This delivers the exposure in one exchange-traded line.globalxetfs.com

• USIG Costs 0.04% a year, against a category median near 0.19%. CORP, which tracks the same ICE BofA US Corporate Index, charges 0.41%.
• One ticker, the full USD investment-grade corporate curve: thousands of bonds, short to long. Slice funds like IGSB (1-5 year) and IGIB (5-10 year) each cover one segment.ishares.com
• Running since 2007, it has tracked its index with very little drift and is one of the more actively traded funds in its category.
• Interest lands monthly, and this is a multi-billion-dollar fund that ranks among the strongest implementations in its peer group.

Worth knowing

• GXIG Thinly traded and still small, so bid-ask spreads can run wider than the giant index alternatives in this space.
• The active call costs real money: VCIT charges 0.03%, and USIG, SPIB and IGIB 0.04%. GXIG asks several times that for a model-driven portfolio.
• Launched in 2025, so there is little history yet showing how the model handles a full credit cycle.

• USIG Owning the whole curve means long-dated bonds ride along, so the price swings more when rates move than a short-maturity slice such as IGSB.
• This is corporate credit, not Treasuries. Investment grade at purchase, but prices can fall when spreads widen or an issuer is downgraded.ishares.com
• VCIT edges it on fee at 0.03%, though that fund stays in intermediate maturities rather than the full curve.
