What is a black swan event in markets?

A black swan event is a rare, high-impact occurrence that markets did not anticipate and that standard models failed to price, recognised mainly in hindsight. The term, popularised by Nassim Taleb, describes outcomes outside normal probability ranges. Examples often cited include the 2008 financial crisis and sudden liquidity collapses in crypto. Because such events break the assumptions behind tools like Value at Risk, they argue for diversification and sizing that survives the unexpected rather than forecasts that avoid it. Building portfolios that account for tail events is part of the research discipline Qatobit documents. Read the methodology for how that thinking is structured.
