Risk & position sizing
How do I use a risk matrix to systematically map out improbable black swan events?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
A risk matrix maps potential events by likelihood and impact severity, helping traders systematically consider low-probability but high-impact black swan scenarios alongside more routine, frequent risks.
How it works
By plotting scenarios like flash crashes, liquidity freezes, or broker insolvency on a grid, investors can prioritize which tail risks warrant hedges, insurance, or reduced exposure despite their rarity.
An example
An investor rates a potential exchange outage as low probability but high impact, prompting them to diversify broker relationships rather than concentrating all assets at one firm.
Risk & limitations
Risk matrices rely on subjective probability estimates, and true black swan events are by definition difficult to anticipate or accurately quantify in advance.
