Short-term statistical arbitrage
Thousands of tiny, repeatable pricing errors — engineered, not guessed.
Anatomy of the strategy
Capture faint pricing errors across minutes to days using statistical patterns and cost-aware execution.
Models such as cointegration tests and hidden Markov chains detect anomalies between related assets; execution is fully automated with latency and slippage compressed to the limit.
Thousands of tiny, repeatable edges compound into meaningful returns when transaction costs are engineered to near zero.
Model decay, regime shifts, and execution slippage. A pair that cointegrated for two years can break in a week.
How the desk runs it
A loop, not a tip — the same four steps, every day, without exception.
Scan the universe
Every pair of related securities is tested for a stable statistical relationship — correlation is not enough; the spread must be proven mean-reverting out of sample.
Reject almost everything
Renaissance-style desks are defined by their rejection rate. Most apparent anomalies are noise; a strict gate keeps false discoveries out of the book.
Size by conviction and cost
Position size follows signal strength minus expected transaction cost. An edge that cannot survive fees is not an edge.
Mark to the thesis, daily
Every open position is tracked against the evidence that justified it. When the relationship weakens, the position is cut — no narrative, no hope.
