Capital Markets

Capital markets firms investment banks (bulge bracket and boutique), prime brokers, inter-dealer brokers, and market makers operate the infrastructure that intermediates securities and derivatives flow between issuers, institutional investors, and each other. The sell-side business model monetises four primary activities: client execution (agency brokerage), principal market making, securities underwriting, and financing (prime brokerage, securities lending, repo). Each activity has distinct risk and P&L profiles but shares a common dependency on real-time pricing, risk, and analytics.

Pricing of derivatives and structured products is the canonical application of quantitative finance on the sell-side. The Black-Scholes-Merton model and its extensions (local volatility, stochastic volatility, SABR) are the pricing backbone for equity and rates derivatives. Credit derivatives require their own models (Gaussian copula, intensity models). Structured products autocallables, reverse convertibles, exotics are priced and hedged as a portfolio of simpler instruments (the so-called building blocks approach). TQH TERMINAL implements the full pricing library and supports the building block decomposition for exotics.

Risk management on the sell-side operates at three levels. Market risk: VaR, ES, and sensitivity-based limit monitoring at desk, business line, and firm-wide levels. Credit risk: counterparty exposure (CVA), issuer risk (jump-to-default), and settlement risk. Operational risk: trading errors, booking errors, model risk. TQH TERMINAL and ARMS together cover market and counterparty risk across the full trade population in real time, with limits management and escalation workflow.

Electronic trading is now the dominant execution channel in most asset classes. TQH TRADING AGENT provides a FIX 5.0/5.0 SP2 and FpML 5.13 compatible electronic trading platform for fixed income, with sub-100 microsecond internal latency, RFQ and streaming protocols, a market data engine, and a built-in data lake for trade reconstruction and compliance. The platform supports both agency execution (passing through client flow to venues) and principal market making (internalising flow with the bank's own axe).

TheQuantHackers supports the full sell-side workflow in the integrated TQH ecosystem. TQH TERMINAL provides pricing and risk, ARMS provides the risk aggregation and limits engine, TQH TRADING AGENT provides the electronic trading layer, and TQH MACRO TERMINAL provides historical data and reference data. Integration is via shared services: market data, reference data, position master, and a common calculation layer that produces both internal risk and regulatory templates from the same source.
