MIG vs VTC

MIGBVanEck Moody’s Analytics IG Corporate Bond ETF

VTCAVanguard Total Corporate Bond ETF

In short

MIG Most investment-grade bond funds buy the index and move on. MIG hands the screening to Moody's Analytics, whose credit work sorts roughly 400 corporate bonds on quality and value before they get in.

VTC Most cheap corporate bond funds sell you one slice of the maturity curve. VTC buys the whole investment-grade corporate market, short to long, for 0.03% a year, and since 2025 it owns the bonds directly instead of stacking three Vanguard funds.

Stated mandate

MIG The Fund seeks to track, before fees and expenses, the price and yield performance of the MVIS Moody’s Analytics US Investment Grade Corporate Bond Index.

VTC The Fund seeks to track a broad, market-weighted corporate bond index, specifically the Bloomberg U.S. Corporate Bond Index. It uses an indexing approach focused on investment-grade, fixed-rate, taxable corporate bonds.

Why people hold it

• MIG The selection engine is the point: the MVIS Moody's Analytics US Investment Grade Corporate Bond Index screens IG credit on quality and value rather than taking the market as it comes.vaneck.com
• It does what the label says. Tracking of its stated index has been close, one of the tighter implementations among investment-grade corporate peers.vaneck.com
• About 400 corporate bonds, distributions paid monthly, and a 0.20% fee that sits within a hair of the typical IG corporate ETF.

• VTC 0.03% a year against a 0.19% median for investment-grade corporate ETFs. On this exact Bloomberg index, nothing in the group charges less.
• One ticker, the full corporate curve. Top-graded rivals like VCIT, IGIB and IGSB each buy a single maturity band; VTC's index spans short, intermediate and long fixed-rate corporates.
• No overlays, no active tilts, no credit guesswork. Market-weighted indexing of investment-grade, fixed-rate, taxable corporates, and the portfolio hews tightly to that mandate.
• Income lands monthly, not quarterly, which matters if bond coupons are doing real work in your cash flow.

Worth knowing

• MIG A small fund that trades thinly, so spreads can run wider and orders land less smoothly than in the giant IG bond ETFs.
• That 0.20% pays for the Moody's screen. Plain broad IG index funds such as VCIT and IGSB charge a small fraction of it.
• Launched in 2020, so its live record is short next to IG funds that have run through several credit cycles.

• VTC Whole-curve means long bonds in the mix, so prices move more with interest rates than a 1-5 year slice like IGSB does.
• The plumbing changed in March 2025: Vanguard moved it from holding three underlying corporate bond ETFs to buying the index bonds directly. Same objective, same index.sec.gov
• Moderately traded rather than a volume heavyweight, so spreads can run wider than the busiest corporate bond funds, particularly in choppy markets.
