Data Algebra prepares historical evidence: selecting observations, aligning dates and calculating features. Strategy Algebra assembles rules for selection, holding, replacement and allocation.
AI agents coordinate these steps within an approved research plan and explain the outcome. Discovery explores a defined family of combinations; the plan sets the scope, and the manager approves each order basket before broker submission.

Questions and answers.
Corbex runs systematic strategies on the founder’s family capital account. These answers cover how strategies are found, reviewed and reported.
Does Corbex accept outside capital?
No. Closed fund. Not accepting outside capital. Corbex manages the founder’s family capital account, and nothing on this site is an offer or a solicitation.
What is a strategy?
A strategy is a distinct set of backtested rules. Its signals and scoring method determine how stocks are ranked, selected and managed within risk limits.
The rules guide recurring decisions; holdings change as new data affects the rankings and risk limits.
How are strategies discovered?
Within an approved research plan, agents examine relevant market data, search for signals, build portfolio-rule variations and backtest them together.
Candidates are compared on returns, drawdowns, volatility, risk-adjusted statistics and benchmark comparisons. Their evidence, weaknesses and tradeoffs are reviewed before a strategy is deployed.
How does a strategy reach the market?
The review frequency is part of each strategy and its backtest. At each review, the rules are applied to current data to produce a target portfolio.
The manager reviews the order basket before broker submission; the account is then reconciled and monitored daily.
How should I read a backtest?
A backtest applies a strategy’s rules to historical data. It shows how the rules would have behaved, including returns, drawdowns, volatility and benchmark comparisons, not the results of actual trading.
Past performance is not indicative of future results.

Any family capital account results shown are unaudited, approximate results of private family accounts, not a fund record. Past performance is not indicative of future results. Investing involves risk, including loss of principal.
