What Is SPTL? State Street SPDR Portfolio Long Term Treasury ETF

SPTL is State Street SPDR Portfolio Long Term Treasury ETF, an ETF that tracks a long-dated US Treasury index at a 0.03% expense ratio. SPTL holds long-dated US Treasury, bundled into one ticker. It launched in 2007. It charges 0.03%. It distributes about 4.17%, and that payout moves with rates rather than being fixed.

SPTL is issued by State Street SPDR and tracks a long-dated US Treasury index, so a single ticker gives you the whole portfolio of underlying holdings weighted by the index's methodology rather than by any active stock-picking.

SPTL does not hold a basket of individual stocks. It gets its exposure synthetically, through derivatives such as swaps and futures rather than by owning the underlying shares, so there is no conventional top-10 equity holdings list. See the description above for what SPTL actually tracks and how that exposure is built.

There are three common ways to get SPTL exposure. Buy shares (or fractional shares) of SPTL directly at any major broker that lists it. Hold it as a core position and layer more concentrated ideas on top. Or build it into a thematic portfolio in Walnut, so SPTL sits alongside other holdings that express the same thesis, with target weights you can rebalance toward. SPTL trades like a stock during market hours, so you buy it the same way you would any listed share.
