KORPBAmerican Century Diversified Corporate Bond ETF

SPBOAState Street SPDR Portfolio 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.

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

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.

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

  • 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.
  • 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

  • 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.
  • 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.
