What is Atoti Risk Services?

Atoti Risk Services is a managed, cross-asset risk engine that computes VaR, P&L Explain, and Risk Factor Decomposition (breaking a risk or P&L figure down by contributing factor) across more than 80 products. It ingests positions, market data, and reference data, then delivers the resulting risk analytics through its own web-based Risk Portal, or as a feed that other Atoti products can work with. Atoti Risk Services serves sell-side and buy-side institutions, exchanges, and central clearing counterparties in capital markets.

​

Why use Atoti Risk Services?

Building and maintaining a cross-asset risk engine in-house takes years and requires a large team of quants and engineers. Even after that investment, the resulting numbers often reach the desk too late to be useful. The problem compounds for firms running separate engines for listed, OTC, and structured products: producing one consistent set of numbers across the business becomes difficult, and explaining a single risk figure can require a multi-day investigation. Atoti Risk Services addresses these problems directly.

• Ready on day one. The service is API-first and cloud-delivered, with reference data, pricing models, and risk analytics maintained by ActiveViam.
• Live risk and what-if on one engine. Trade impact, portfolio shifts, and ad hoc scenarios run on the same engine that produces the reported numbers, instead of a separate batch process.
• Transparent by design. Every figure drills down to the underlying trade, market data point, and model assumption.
• One consistent set of numbers. A single cross-asset engine replaces separate engines for listed, OTC, and structured products.
• Lower total cost of ownership. A managed service reduces the quant and engineering capacity needed to run an in-house risk stack.

​

Who is Atoti Risk Services for?

Atoti Risk Services is used by teams that need cross-asset risk analytics without building or operating the underlying risk engine themselves. Typical users include:

• Front office traders and portfolio managers on the sell side and buy side.
• Market risk and enterprise risk teams.
• Quantitative analysts validating models and pricing.
• Regulatory and management reporting teams.

Common use cases include:

• Calculating VaR, P&L Explain, and Risk Factor Decomposition across asset classes, from top-of-house down to a single trade.
• Running pre-trade what-if analysis and stress and scenario testing.
• Monitoring funding, liquidity, and collateral utilization, including initial and variation margin and SIMM-based calculations.
• Producing intraday and end-of-day regulatory and management reports, including OPERA and ESMA reporting.

How does Atoti Risk Services work?

Atoti Risk Services ingests positions, market data, and reference data, then computes VaR, P&L Explain, and Risk Factor Decomposition across more than 80 products, from vanilla instruments to structured exotics. Every computation round prices all positions against the same market view, so a stock, its options, and a convertible into that stock are valued consistently with each other. The resulting greeks are mutually consistent across stocks, options, and convertibles, rather than assembled from values struck at different moments. It runs as a cloud-native platform. It can be consumed as a standalone service with APIs and a managed Risk Portal, or as a layer that feeds its computed risk analytics into the Atoti Engine, alongside data the Engine ingests from other sources.

What is the relationship to other Atoti products?

Atoti Risk Services is one of the data sources that the Atoti Engine can use. Atoti Engine aggregates the risk analytics that Atoti Risk Services computes, alongside data the Engine ingests from other sources in parallel. Any cube built on the Engine can use data that originates from Atoti Risk Services. Atoti Intelligence gives AI agents native access to the cube, which can include data from Atoti Risk Services as well as any other data in the cube.
