Black swan event

A black swan event is an extremely rare and unexpected occurrence that has severe financial market impacts. Such events are characterized by their unpredictability, significant consequences, and the tendency for people to rationalize them in hindsight as if they were foreseeable. They typically cause extreme price movements, often leading to rapid and substantial market crashes or surges.

For retail traders, black swan events present significant risk due to their sudden and extreme nature. Stop-loss orders may experience severe slippage, executing far from the intended price and causing losses much larger than anticipated. These events can trigger margin calls or even stop-outs, potentially wiping out substantial portions of a trading account quickly. Effective risk management strategies are crucial.
