SPLB

SPLB is a passive bond ETF built to track the Bloomberg U.S. Long-Term Corporate Bond Index, targeting investment-grade, fixed-rate, taxable U.S. dollar corporate bonds with 10+ years remaining maturity.

It uses market-value weighting and typically holds most of the index, but can use sampling (owning a representative subset) to closely mirror the index’s risk/return profile.

The index is refreshed monthly, so the portfolio stays aligned with the long-term IG corporate bond market.
