The key difference between the Vanguard Short-Term Corporate Bond ETF (VCSH 0.03%) and the iShares 1-5 Year Investment Grade Corporate Bond ETF (IGSB 0.04%) is breadth: IGSB is more diversified, while VCSH is modestly cheaper and larger in terms of its assets under management (AUM).
Both funds aim to provide steady income with limited interest rate risk by focusing on short-term, investment-grade U.S. corporate bonds. This comparison between VCSH and IGSB examines costs, returns, risk, and underlying portfolio differences to help clarify which approach may appeal to different fixed income investors.

What's inside
IGSB spreads its assets across a vast pool of 4,435 investment-grade U.S. corporate bonds, providing substantial diversification. It provides access to bonds with one- to five-year maturities, and the fund has an established history of close to 19 years.
VCSH, in contrast, maintains a smaller portfolio with 2,552 bond holdings. Like IGSB, it holds investment-grade corporate bonds with a dollar-weighted average maturity of one to five years, though it has a slightly shorter track record of 16 years.

Foolish take
IGSB and VCSH are similar in many ways. They both hold thousands of short-term, investment-grade U.S. corporate bonds, they've earned similar one- and five-year total returns, and they have nearly identical dividend yields and expense ratios. They also have roughly the same risk profile, and with virtually the same max drawdown, neither has experienced more significant volatility than the other.
The primary difference between them comes down to diversification. IGSB holds close to 2,000 more bonds than VCSH, which can be an advantage for those looking to maximize their exposure to the corporate bond space.
However, VCSH has a much larger AUM, which can provide greater liquidity and, in some cases, a lower fee. Long-term investors may not be as impacted by AUM, but it's a factor to consider when deciding between these two very similar funds.
