Institutional risk models for the individual investor
Ceiora is a portfolio risk management platform built on a family of bespoke factor models that decompose risk exposures. Ceiora distinguishes itself from traditional factor models by focusing on the unique needs of individual allocators and retail investors. In this vein, each of our models are designed to be actionable, interpretable, and approachable.
01
cUSEBarra-style equity risk
cUSE is the descriptor-native engine. It estimates exposures from company characteristics, industry structure, and orthogonalized style descriptors so the platform can explain portfolio risk in a stable, interpretable factor language.
02
cPARReturns-based equity risk
cPAR is the tradable proxy engine. It fits market, sector, and style sleeves in residualized ETF space so you can read incremental risk clearly and move directly from diagnosis to hedgeable action.
03
cMACMulti-asset macro risk
cMAC is the forthcoming macro layer. It will extend the platform beyond single-book factor diagnosis by framing exposures against rates, inflation, growth, credit, and liquidity regimes that shape how portfolio risk transmits through the broader market.
cUSE
Barra-Style US Equity Model
cUSE keeps the descriptor-native philosophy, but trims complexity on purpose: fewer style factors, a smaller industry burden, and ordered orthogonalization so the outputs remain understandable enough to manage instead of becoming a research object.
- Core universe
- 3K+
core-estimated- Live factors
- 45
14 style- Industry groups
- 30
business sectors
- Lineage
- Barra USE4 lineage, but narrowed to a smaller live factor set, a tighter industry list, and style blocks that are orthogonalized in a clean dependency order
- Tradeoff
- The model gives up breadth and institutional granularity so the factor language stays interpretable, maintainable, and harder to overfit in day-to-day use
- What you get
- A native-factor decomposition that favors stable structure and actionable explanation over exhaustive factor sprawl
cPAR
Returns-Based Equity Model
cPAR applies the same restraint in returns space: fixed ETF proxies, package-level market orthogonalization, and one-shot weighted ridge so the model stays broad, tradable, and easily maintainable.
- Fitted universe
- 3K+
active package- ETF proxies
- 17
SPY + sector + style- Weekly bars
- 52
one-year window
- Lineage
- A fixed registry of real ETF proxies: SPY, sector sleeves, and a short list of style ETFs, with non-market sleeves orthogonalized to market before the fit
- Tradeoff
- Returns-based breadth and direct hedgeability without inventing bespoke factor portfolios, plus one-shot weekly ridge to keep the fit stable instead of chasing noise
- What you get
- Residualized tradable factor space that keeps market explicit and turns incremental structure into a hedgeable read
