KORP vs VTC

KORPBAmerican Century Diversified Corporate Bond ETF

VTCAVanguard Total Corporate Bond ETF

In short

KORP Most corporate-bond ETFs just clone an index. KORP is run by people: an investment-grade core with a dial that can turn toward high yield, held in a three- to seven-year duration lane.

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

KORP Seeks current income by emphasizing investment-grade debt and dynamically allocating part of the portfolio to high-yield debt. The strategy uses active fundamental and quantitative analysis and generally maintains three- to seven-year duration.

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

• KORP Actively managed, not a tracker. Investment-grade core plus a sleeve that shifts into high-yield debt, a lever index funds in this category don't have.americancentury.com
• Generally runs a three- to seven-year duration, parking rate sensitivity in the intermediate zone instead of the long end.americancentury.com
• The portfolio does what the name says: roughly 400 corporate bonds, global in reach, with a stated monthly income schedule.americancentury.com
• Live since 2018 and sitting in the upper half of a crowded investment-grade corporate field, which is more than most active bond ETFs manage.

• 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

• KORP 0.29% a year is above the category median and many times what index heavyweights like VCIT and SPBO charge. The manager's judgment is the thing you're buying.
• That high-yield allocation can push credit risk past a pure investment-grade portfolio. Flexibility cuts both ways.americancentury.com
• Volume is moderate rather than heavyweight, so spreads can run wider than the most-traded names in the corporate-bond aisle.

• 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.
