Systematic investing
Investing by explicit, pre-defined rules rather than discretion or gut feel — so decisions are repeatable, testable, and free of in-the-moment emotion.
Systematic investing follows a written rulebook: the same inputs always produce the same decision, whatever the mood or the headlines. It stands opposite to discretionary investing, where a manager decides case by case.
Its strengths are consistency and testability — a rule can be examined, backtested, and audited — and its discipline removes many of the emotional errors that hurt investors most. Its limit is that a rule only knows what it was designed to see. It is the core of how Witan Way works.
