Bond ETF Comparison
Direct answer: The major bond ETF categories are investment-grade aggregate (AGG, BND), corporate investment-grade (LQD), high-yield (HYG, JNK), Treasury-focused (TLT, SHY), and short-term (VCSH, SPSB). AGG and BND are the most common core bond holdings, both tracking the total U.S. investment-grade bond market at 0.03% expense ratio.

Frequently asked questions
What is duration and why does it matter for bond ETFs?
Duration measures a bond ETF's sensitivity to interest rate changes. A duration of 6.5 years means a 1% rise in rates causes approximately 6.5% price decline. AGG's duration of ~6.5 years means it would lose about 6.5% if rates rose 1% suddenly. Long-duration ETFs like TLT (~17 yr duration) are extremely sensitive: they gained dramatically when rates fell 2008-2021, but lost 39% in 2022 when rates rose sharply. Short-duration ETFs like SHY (1.9 yr) are much more stable: 1% rate change causes only 1.9% price movement.
Is HYG/JNK better than LQD?
High-yield ETFs (HYG, JNK) yield more than investment-grade (LQD) because they hold riskier bonds (below BBB-rated) with higher default probability. HYG/JNK behave more like equities during market stress: they fell 23% in March 2020 alongside stocks, while LQD held up better. For bond diversification versus stocks, investment-grade bonds (AGG, BND, LQD) historically provide better portfolio protection during stock market downturns. High-yield bonds are often classified as a separate asset class and not a true substitute for investment-grade bonds in a portfolio context.
Why does BND hold more bonds than AGG?
BND tracks the Bloomberg U.S. Aggregate Float Adjusted Index (approximately 10,000+ bonds), while AGG tracks the Bloomberg U.S. Aggregate Bond Index (approximately 10,000 bonds as well). The differences are minor: BND explicitly floats-adjusts its weights (excluding Fed and foreign-held bonds), while AGG has evolved to do similarly. Both cover the same universe: U.S. investment-grade bonds with at least 1 year to maturity across Treasuries, agencies, corporate bonds, and mortgage-backed securities. For practical purposes, AGG and BND are nearly identical funds that can be used interchangeably.
