03 — Approach

Only ideas that can be tested are traded.

Every strategy follows the same path from hypothesis to live allocation, and every strategy can be removed from it.

Premise

A market observation is not a strategy. It becomes one only after it has been stated precisely enough to be wrong, tested against data it was not built on, and run with real capital under limits set in advance.

Most candidate ideas do not survive that sequence. The discipline is in discarding them.

01

Hypothesis

An observation about market behaviour is written down as a specific, falsifiable claim — what is expected to happen, in which market, under what conditions, and what evidence would show the claim to be false.

02

Data

The data required to test the claim is assembled and checked before any testing begins: coverage, gaps, corporate actions, survivorship, and the difference between what was knowable at the time and what is knowable now.

03

Out-of-sample testing

The hypothesis is tested against periods held back from its construction, with transaction costs, slippage, and realistic fill assumptions applied. A result that only holds on the data used to build it is treated as no result.

04

Limited deployment

A strategy that survives testing is run in live markets at a deliberately small size. The purpose is to compare live behaviour against expected behaviour, and to expose the operational faults that only appear in production.

05

Allocation

Capital is allocated only after live behaviour matches expectation, and always within limits set before the allocation is made. Allocation decisions follow a documented process rather than any individual's discretion.

06

Monitoring

Live strategies are monitored continuously against the behaviour they were expected to show. Divergence between the two is treated as a signal about the strategy, not as noise to be waited out.

07

Retirement

A strategy is reduced or withdrawn when its premise no longer holds, when its behaviour departs from expectation, or when the conditions it relied on are no longer present. Retirement is a normal outcome, planned for at the outset.

On change

Markets change. Strategies are evaluated continuously against changing market conditions, and the allocation of capital between them follows a documented process that responds to what those evaluations show.

This is a statement about process, not about outcomes. No method is expected to hold in all conditions, and none is treated as though it will. The purpose of the sequence above is to notice as early as possible when something has stopped working, and to act on it.

Not published

The firm does not publish its strategies, the signals they use, their holding periods, their positions, or their results. It does not publish market commentary, outlooks, price targets, or trade ideas, and it does not offer views on any instrument to anyone outside the firm.
