Modeling Fixed-Income ETF Prices from Bond Index Cash Flows

Summary

The document describes a student fund’s effort to improve how it represents a domestic government bond index held through fixed-income ETFs. Its current approach treats the index as one bond, discounts projected cash flows, and feeds that estimated value into a utility-based allocation model. The team wants a more accurate price model while retaining the existing allocation framework, and asks for models, papers, or textbooks to guide the work.

The note offers a useful modeling problem and identifies the team’s limited fixed-income background, but it does not supply a proposed method, references, or empirical evidence. It also does not specify the index composition, ETF tracking mechanics, valuation date, or available market data, all of which would matter when choosing an approach. As presented, it is a request for research direction rather than an evaluated pricing method, so it cannot establish that a particular alternative improves valuation or portfolio allocation.

Key ideas

• The fund models a government bond index as a single bond and discounts its projected cash flows.
• The resulting estimated value enters a utility-based portfolio allocation model.
• The team seeks a more accurate way to value fixed-income ETF holdings while retaining its allocation framework.
• The document requests references but provides no pricing model, evidence, or comparison.

Apologies, if this is a bit of a stupid question, very new to the forum, and been trying to search for answers on how to go about this, but wasn't able to find anything useful online.

I'm in a team in our Student Managed Fund that is more macro oriented and allocates towards various equity and fixed-income ETFs. We're currently looking to bolster how we model our fixed-income holdings (Domestic Government Bond Index), which at present treats the entire index as a singular bond, then discounts all future cash flows to determine the total bond price, which is then further used as an input to determine the "optimal allocation" via a utility based model.

Unfortunately, we cannot replace the utility model, but I'm really interested in how we can go about more accurately determining the price of the bond index. Our team has quite strong quantitative skills (undergrad comp-sci, statistics and applied-math backgrounds), so we're really not afraid to make a more complex model. However, we're completely starting from scratch - we understand very basics of fixed-income products, but nothing much else - so was just wondering if there are any specific models, academic papers, textbooks that we should look out for.
