Definition of Tail Risk
Tail Risk is a form of portfolio risk that refers to the potential for an investment to experience extreme changes in value due to rare events that lie beyond three standard deviations from the mean in a normal distribution. These events can result in significant losses and are considered low probability but high impact.
Tail Risk vs Other Risks
| Tail Risk | Standard Risk |
|---|---|
| Concerns extreme changes (left or right) in value, particularly on lower tail events (losses). | Deals with usual fluctuations around the mean, typically within one or two standard deviations. |
| Often ignored in traditional models (because who likes to think about walking into a bear pit?) | Generally well understood and modeled using normal distributions (like a predictable dog barking!). |
| Rare events with significant consequences (like finding out your ex is dating your best friend!). | More common events that can be estimated and planned for (like a rainy day). |
Examples of Tail Risk
- Market Crashes: Events like the 2008 financial crisis that caused a sudden drop in market value are examples of tail risks.
- Unexpected Political Events: Political upheavals, natural disasters, or pandemics that have a low chance of occurring but can have dramatic effects on financial markets.
Related Terms
- Kurtosis: A measure of the “tailedness” of a probability distribution; high kurtosis indicates a significant presence of tail risk.
- Value at Risk (VaR): A statistical technique that assesses the risk of loss on an investment portfolio.
- Black Swan Events: Unpredictable or unforeseen events statistically beyond the realm of normal expectations that have potentially severe consequences.
