Unsystematic risk is the chance of loss tied to one firm or sector, such as a product recall, a management crisis, or a regulatory hit that leaves the rest of the market largely untouched. Spreading money across many unrelated holdings can shrink this type of risk. It does not remove risks that hit everything at once.
Key takeaways
- Company specific news is the classic source of unsystematic risk.
- Diversification is the main tool for reducing it, not eliminating market wide shocks.
- Concentrating in a single stock maximises your exposure to that firm’s unique problems.
- Analysts separate this idea from systematic risk, which affects broad markets and is harder to diversify away.
