SPIB

SPIB is a passive bond ETF built to track the intermediate-term slice (1–10 years) of the US investment-grade corporate bond market, as represented by a Bloomberg intermediate corporate bond index.

It uses a sampling approach, meaning it may hold a representative subset of the index bonds (plus limited cash-like instruments) to closely match index risk/return.

The index is market-value weighted and rebalanced monthly, so the biggest corporate issuers tend to have the biggest impact.
