IG vs VTC

IGBPrincipal Investment Grade Corporate Active ETF

VTCAVanguard Total Corporate Bond ETF

In short

IG Most investment-grade corporate bond ETFs just buy the index. IG hires a manager to pick the credits, charges 0.19% (the category median), and pays income monthly. Active credit work at an index-adjacent price.

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

IG The Fund seeks current income and, secondarily, capital appreciation.

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

• IG Actively managed, not index-tracking: the manager can lean into or step away from individual issuers and sectors instead of owning the market by weight.
• At 0.19%, it costs the same as the typical investment-grade corporate bond ETF. The active mandate doesn't come with an active-management markup.
• Income comes first in the mandate (current income, with capital appreciation secondary), and distributions are paid monthly.
• Trading since 2018, with a portfolio that lines up closely with what the prospectus says it does. Sits in the upper half of its investment-grade corporate peer group.

• 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

• IG Thinly traded compared with the index heavyweights, so bid-ask spreads can be wider and bigger orders need more patience.
• That 0.19% is several times the 0.03%-0.04% charged by the largest index peers, VCIT and USIG. The gap is the price of the manager's judgment.
• A small fund next to the multi-billion-dollar index leaders in this corner of the bond market.

• 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.
