SPTL

SPTL is a passive ETF designed to track a Bloomberg long-term U.S. Treasury index, meaning it targets Treasuries with 10+ years remaining until maturity.

It uses a sampling approach, so it may not own every bond in the index—just a basket intended to closely match the index’s overall risk/return profile.

Under normal conditions, it keeps at least 80% of assets in index bonds or near-equivalent exposures, with some flexibility to hold cash-like instruments for implementation.
