Risk management is often described as the single most important discipline in both investing and trading — more important, in many respects, than the specific strategy used to select positions.
Core principles
- Position sizing: limiting how much capital is exposed to any single decision.
- Diversification: spreading exposure across assets that don't move identically.
- Defined exits: knowing in advance when you would exit a position, in both directions.
- Capital preservation: prioritizing the avoidance of catastrophic loss over maximizing every gain.
Why risk management is often overlooked
It's less exciting than finding the next winning idea, and its benefits are most visible in hindsight — during a downturn that a well-managed portfolio survives more comfortably than a poorly managed one.
Applying it consistently
Risk management is most effective when applied consistently, as a rule rather than a reaction — decided in advance, not improvised under the pressure of an open position.
