IGSB vs VCSH

IGSBAiShares 1-5 Year Investment Grade Corporate Bond ETF

VCSHAVanguard Short-Term Corporate Bond ETF

In short

IGSB Corporate credit with the rate risk dialed down: roughly 4,700 investment-grade bonds, none maturing past five years, for four basis points. iShares has run it since 2007.

VCSH Corporate credit, kept short. VCSH tracks an index of investment-grade company bonds maturing in one to five years, at three basis points: you take company credit risk instead of government risk, with muted sensitivity to rate moves.

Stated mandate

IGSB The fund seeks to track an index containing U.S. dollar-denominated investment-grade corporate bonds with remaining maturities from one through five years.

VCSH The fund seeks to follow a market-weighted corporate bond index with a short-term dollar-weighted average maturity, using index sampling and investing at least 80% of assets in index bonds.

Why people hold it

• IGSB Four basis points a year, a fraction of the typical investment-grade corporate bond fund's fee and level with the cheapest tier of its peer group.
• One-to-five-year maturities mean prices move less when rates move than long-dated corporate funds. Same corporate credit, shorter leash.ishares.com
• Thousands of individual bonds tracking the ICE BofA 1-5 Year US Corporate Index, with income paid monthly.ishares.com
• Trading since 2007, actively traded, and one of the strongest builds in the investment-grade corporate group on cost, portfolio and execution.

• VCSH A 0.03% expense ratio, versus a 0.12% median across its peer group. That is Treasury-index pricing for a fund doing corporate credit work.
• Running since 2009 and now a multi-billion-dollar fund that trades actively, which is one of the easier profiles to get in and out of in its category.
• Samples the Bloomberg U.S. 1-5 Year Corporate Bond Index with at least 80% of assets in index bonds, and its book lines up closely with that benchmark.vanguard.com
• Distributions land monthly, not quarterly, and it sits among the strongest implementations in its cost-and-tracking peer group.

Worth knowing

• IGSB Short maturities cut both ways: less price damage when rates rise, less lift when they fall.
• These are company bonds, not Treasuries. Investment grade, but credit spreads can widen and prices move with them.
• Only the front of the curve. Sibling IGIB runs 5-10 years and USIG spans broad maturities, both at the same fee.

• VCSH These are company bonds, not government paper. Investment grade, but credit spreads can widen when markets get nervous, and Treasuries do not carry that risk.vanguard.com
• The one-to-five-year maturity band cuts both ways: smaller price swings when rates jump, and less duration to work with when rates fall.vanguard.com
• Index sampling means it holds a representative slice of the benchmark rather than every bond in it, so small differences from the index are normal.vanguard.com
