Corbex Funds Management

Quantitative investing, built for family capital.

Closed family fundRule 506(c) of Regulation D

Corbex builds and operates highly automated quantitative strategies that deploy family capital in US equity markets. We gather diverse point-in-time data from multiple sources, process it into governed datasets, and build models designed to extract weak, repeatable signals under explicit risk controls. Today we operate one live quantitative strategy, Arbiter.

How Corbex operates

From market data to deployed capital.

Corbex Funds Management is a research and capital-management company. We collect and process data, build models, and deploy family capital through a governed, data-driven process.

01

Gather point-in-time market intelligence.

We acquire and gather available information about markets, companies, sectors, analyst research, company reporting, and other point-in-time historical sources.

02

Clean and normalize diverse data.

We reconcile, timestamp, clean, and normalize the inputs into governed datasets that can support reproducible research and model development.

03

Train models to extract weak signals.

Our models learn from noisy data to identify weak market and company signals. Proprietary aggregation mechanisms combine those signals into stronger decision inputs.

04

Construct a controlled long-short book.

Portfolio rules translate ranked signals into a concentrated book of companies and ETFs, using long and limited short positions under explicit exposure controls.

05

Deploy target exposure through proprietary agents.

Our deployment agents prepare target exposures and route manager-approved order baskets to brokerage accounts through a controlled daily process.

06

Publish an explicit mark-to-market record.

Brokerage integration reconciles mark-to-market performance and supports dated publication of live and simulated records with explicit methodology and disclosure.

I founded Corbex to bring my experience in production data engineering and analytics to systematic market research.

We collect and organize point-in-time company, market, rates, volatility, and cross-asset data in a governed data lake. That foundation lets me model market dynamics and capital flows at a nuanced level, extract signals that identify strong companies, and detect periods of market stress.

Corbex exists to build data-driven strategies, deploy them first with family capital, and establish transparent live operating records. That is our current focus with Arbiter.
