What it can do
| Tool | What it says it does |
|---|---|
ncsx_bond | Filtered lookup for one issuer, ticker or note keyword (e.g. "CoreWeave", "GLXY", "Helios", "2031") — returns only the matching constituent bonds, not the whole universe. Constituents are identified by issuer + coupon + maturity; they do NOT carry CUSIPs, so never query by CUSIP. Use… |
ncsx_constituents | The whole universe in one response — all 13 constituent bonds, no filter: issuer, ticker, coupon, maturity, size, seniority, pricing date, tenor, the matched Treasury yield on that date, and the resulting issuance spread in bp. Use it to list the index or to compute weights; if the user named one… |
ncsx_curve | The US Treasury par-yield curve used on the pricing date (14 tenors, interpolated linearly, never extrapolated) plus its recent history. Every constituent spread is measured against this curve. |
ncsx_events | The index history — use this when the question is "how did NCSX-IS get to its current level" rather than "what is the level". NCSX-IS is event-driven: it only moves when a new bond prices, so the history is a replay of 13 pricing events from 2025-05-19 to 2026-07-24. Each event returns the date… |
ncsx_facts | The quotable-facts layer: 16 pre-computed, individually sourced numbers covering the whole index — index and sub-index levels, the secured-vs-unsecured structure premium, universe size, per-bond spread range, peak maturity year and its share, the 2030 window, N-PORT marks coverage and implied… |
ncsx_filings | SEC filing radar for the 9 AI-infrastructure issuers covered by SpreadBench (6 in NCSX-IS plus Nebius, IREN and Hut 8 on the watchlist): every filing from the last 45 days, noise forms (ownership, routine) filtered out, pricing-chain forms (FWP, 424B*, S-3*, F-10) flagged with pricing_signal=true… |
ncsx_index | The full index definition, not a single number — use when the question is structural ("how is NCSX-IS built", "show all tiers") rather than "what is the level". Returns the NCSX-IS / secured / unsecured tiers side by side with each tier's notional and constituent count, plus index-level coverage… |
ncsx_latest | The one number to quote — use this first for "what is NCSX-IS / what is the spread right now". Returns a compact record: headline issuance spread (coupon minus the Treasury yield of matching tenor on the pricing date, weighted by face value), the secured and unsecured sub-indices… |
ncsx_marks | Second, independent layer: quarterly fair-value marks for AI-infrastructure bonds as reported by US registered funds on SEC Form N-PORT (Level 2), converted to spread over the matched Treasury. Compare with NCSX-IS to see issuance spread vs. mark spread. |
ncsx_methodology | Methodology metadata and full formula chain: version, DOI, license, data sources and their licensing status, the exact spread and weighting formulas, and what is explicitly NOT measured. |
ncsx_ruler | Reverse pricing — the question every other tool cannot answer: given a coupon and a tenor, where would a new AI-infrastructure bond land? Returns the matched Treasury yield (linear interpolation between the two adjacent curve tenors, never extrapolated), the resulting issuance spread in bp using… |
ncsx_sector | Context series for the AI-infrastructure credit complex: US high-yield OAS, US investment-grade OAS and related ICE BofA indices, with 30-day change and daily history — use these to compare NCSX-IS against the broader market. |
ncsx_stories | Citable data stories (editorial layer) recomputed live from the same public data as the index, each with headline numbers, bilingual page URLs and a ready-to-post 1200x630 share card: (1) the maturity wall of the peak year; (2) the CoreWeave repricing — every CoreWeave bond widened 191-258bp… |
ncsx_wall | Maturity wall for AI-infrastructure bonds: outstanding face value by maturity year, split secured / unsecured, with the full bond list per year. As of 2026-11-04, $17.86B (63.6% of the index) matures in 2031, and 7 of those 8 bonds priced within 2026 — a single issuance window produced a… |
