Tail Risk

Tail risk is the possibility of an extreme, unexpected market event that falls far outside normal trading patterns. You'll hear about it when investors discuss worst-case scenarios—like a stock crash, sudden interest rate shock, or geopolitical crisis that moves markets in ways historical data didn't predict. It matters because these rare events can wipe out gains or trigger sudden losses that standard risk calculations miss. Think of it like insurance: most days the market behaves predictably, but tail risk is that 1-in-100 scenario where everything breaks down at once. Smart investors account for tail risk by diversifying their portfolio or using hedging strategies, rather than assuming "normal" conditions will always hold.
