USA - A black swan event is a term used on Wall Street that refers to a rare and unpredictable occurrence that is beyond what is expected and has severe consequences. It's derived from European explorers who had previously thought that all swans were white and only white, as that was all they knew. They were overcome with shock and confusion when Dutch explorer Willem de Vlamingh discovered the existence of black swans in Australia.
The coronavirus is a black swan event, which may have serious consequences for your job, the stock market and global economy. The United States economy has been strong with record-setting high levels of employment. The stock market has rebounded incredibly since the financial crisis, increasing the net worth of many Americans.
Historically, when the stock market goes relatively straight up, there is an expectation of a correction somewhere down the road. A correction is about a 5 to 10% drop in value of stocks. It's viewed as necessary, like clearing out the dead brush in a forest to prevent a future fire. Even the wisest minds on Wall Street admit that they can’t anticipate where the next correction will come from and what damage it may bring. It now seems that the coronavirus is that black swan event.
