SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Bond investors struggle to judge whether a bond is genuinely rich or cheap because raw spread and yield information don’t clearly separate rates, credit, and residual effects.

Core Features & Use Cases

  • Spread decomposition that breaks total spread into risk-free (G-spread), credit curve, and residual components to reveal true richness/cheapness.
  • Yield curve + credit curve context using pricing and curve tools to benchmark a bond against appropriate reference structures.
  • Scenario stress testing that verifies whether the rich/cheap view holds under parallel rate shocks (down and up).
  • Common use case: compare a target bond versus peers to determine whether observed spread compensation is sufficient relative to rates and credit fundamentals.

Quick Start

Use the bond-relative-value skill for the ISIN of the bond you’re evaluating to compute spread decomposition and run parallel rate shock scenarios so you can conclude whether it’s rich, cheap, or fair.

Frequently Asked Questions about bond-relative-value

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I determine if a bond is rich or cheap using spread decomposition?

Spread decomposition reveals true bond richness or cheapness by breaking total spread into risk-free G-spread, credit curve, and residual components, isolating the residual effect to show whether observed spread compensation is genuinely sufficient.

How do I stress test a bond's relative value under yield curve shocks?

Stress test bond relative value by running parallel rate shock scenarios from -100bp to +100bp shifts, validating whether the initial rich or cheap conclusion holds consistently across both upward and downward interest rate movements.

What is the residual component in fixed income analytics spread decomposition?

The residual component in spread decomposition represents the remaining bond valuation gap after subtracting risk-free G-spread and credit curve effects, serving as the primary signal for identifying genuine richness or cheapness.

Can I use bond relative value analysis for peer basket comparisons?

Yes, bond relative value analysis supports peer and basket comparisons, allowing you to benchmark a target bond against peers to determine if observed spread compensation aligns with rates and credit fundamentals.

Do I need yield curve and credit curve data for bond relative value analysis?

Yes, bond relative value analysis requires chaining bond price data with interest rate curve and credit curve inputs to compute G-spread and credit-residual splits accurately before drawing rich or cheap conclusions.

Why does my bond spread not clearly show if it is rich or cheap?

Raw spread and yield information fails to clearly separate rates, credit, and residual effects, requiring spread decomposition to isolate the true drivers behind bond richness or cheapness for accurate valuation.
