Our read on ISTB
AThe Agg with the long end trimmed off, plus a dash of high yield. ISTB tracks a broad USD bond index that stops at five-year maturities, so you get core bond plumbing with a fraction of the rate sensitivity, for six basis points.
The fund seeks to track an index of U.S.-dollar bonds rated investment grade or high yield, with remaining maturities from one to five years.
Why people hold it
- Six basis points a year, a fraction of the typical broad bond ETF fee. On a bond fund, every basis point of fee comes straight out of the income you keep.ishares.com
- The index casts a wider credit net than the Agg: investment grade plus high yield, thousands of individual bonds deep.ishares.com
- Nothing in the index matures past five years, so the portfolio carries far less interest-rate sensitivity than full-maturity core bond funds like BND, SPAB or SCHZ.ishares.com
- Running since 2012, multi-billion-dollar, actively traded, and it pays income monthly rather than quarterly.
Worth knowing
- The high yield sleeve adds credit risk that investment-grade-only short bond funds skip.ishares.com
- Short maturities cut both ways: smaller price swings when rates rise, and less lift when they fall.
- Not a cash substitute. The share price moves daily, and maturing bonds get replaced at whatever rates prevail, so the monthly payout drifts.ishares.com
