Sell-Off

A sell-off is a period of rapid, significant price declines across a stock, sector, or the broader market, driven by intense selling pressure. Sell-offs can be triggered by various factors including disappointing earnings, negative economic data, geopolitical events, central bank policy changes, or simply a shift in investor sentiment. The severity ranges from mild pullbacks (2-5% decline) to severe market crashes (20%+ decline). During sell-offs, trading volume typically surges as panic selling overwhelms buy-side demand, and market breadth indicators deteriorate sharply. Sell-offs are amplified by algorithmic trading, margin calls (forced selling by leveraged investors), and stop-loss cascades. While sell-offs create fear and paper losses, they also create buying opportunities for disciplined long-term investors. The distinction between a healthy correction and a dangerous sell-off often only becomes clear in hindsight.
