Panic selling is a term used to describe the act of investors selling off securities in an abrupt and panicked manner, usually due to a sudden drop in market prices or other negative economic news. This behavior can lead to further market declines and can even trigger a financial crisis in some cases. Synonyms for panic selling include mass selling, slump dumping, market rout, or fire sale. These terms all describe the same phenomenon and are used interchangeably in financial circles. It is important for investors to remain calm and avoid panic selling to mitigate their losses and prevent further disruption in the markets.
