Stripped Treasury Securities and Short-Term Bond ETF Valuation

Summary

The note asks how stripped Treasury securities affect the composition and valuation of a short-term Treasury ETF. It quotes index eligibility rules for the fund: eligible securities are publicly issued U.S. Treasury obligations with fixed coupons, a remaining maturity within the stated horizon, and a minimum amount outstanding, while stripped zero-coupon components and inflation-linked debt are excluded. It also points out that a qualifying coupon bond remains represented at its full outstanding amount even if some of its cash flows have later been stripped.

The document poses, but does not answer, whether ordinary Treasury bond prices can be used to estimate the ETF’s fair value or where to obtain stripped-security prices. It provides no explanation of STRIPS mechanics, valuation method, price sources, or evidence. Its useful content is the distinction between index eligibility and subsequent stripping of components, alongside the unresolved question of how that distinction enters practical fund valuation.

Key ideas

• The quoted index rules exclude stripped zero-coupon securities from eligible index constituents.
• A qualifying coupon bond’s index amount is not reduced when individual coupon or principal components are later stripped.
• The document does not establish whether ordinary Treasury prices suffice for ETF fair-value calculations.
• It raises a pricing data question but supplies no method or source for obtaining STRIPS prices.

I saw this paragraph in the SHV prospectus

> The Underlying Index is market valueweighted based on amounts outstanding of issuances consisting of publicly issued U.S. Treasury securities that have a remaining term to final maturity of less than or equal to one year as of the rebalance date and $1 billion or more of outstanding face value, excluding amounts held by the Federal Reserve System Open Market Account. In addition, the securities in the Underlying Index must have a fixed coupon schedule and be denominated in U.S. dollars. Excluded from the Underlying Index are inflation-linked debt and zero-coupon bonds that have been stripped from coupon-paying bonds (e.g., Separate Trading of Registered Interest and Principal of Securities). However, the amounts outstanding of qualifying coupon securities in the Underlying Index are not reduced by any individual components of such securities (i.e., coupon or principal) that have been stripped after inclusion in the Underlying Index. The Underlying Index is rebalanced on the last calendar day of each month.

I don't quite understand how "stripped bonds" works. Can I still use the "normal" treasury bond prices to price the fair value of this ETF for example? How do I look up the "stripped bond" prices?
