IUSB aims to track the performance of the Bloomberg U.S. Universal Index, which includes U.S. dollar-denominated investment-grade bonds across government, corporate, and securitized sectors.

The ETF primarily holds physical bonds rather than derivatives, providing direct exposure to the underlying assets. The fund is rebalanced regularly to align with the index, ensuring consistency with its stated objectives. This passive approach helps keep costs low while maintaining broad market representation.

The U.S. bond market is one of the largest and most liquid in the world, with varying risk and return profiles depending on the type of bond.

Alternative Comparison

Expense ratios are competitive across these funds, making IUSB a viable alternative for investors seeking comprehensive bond market exposure.
