The COVID Flash Crash of March 2020: A Historic Plunge

What Happened March 16, 2020, stands as a pivotal day in the history of the S&P 500, marked by one of the most drastic singleday declines in recent memory, often referred to as the "COVID Flash Crash." As the world grappled with the escalating COVID19 pandemic, fear and uncertainty reached a fever pitch, leading to a relentless selloff across global markets. The SPY, an ETF tracking the S&P 500, experienced an unprecedented freefall, triggering circuit breakers and leaving investors reeling from the sheer speed and magnitude of the market's capitulation. The day began with an aura of immense anxiety, following a weekend of alarming news regarding the spread of the virus and increasingly dire economic projections. From the opening bell, selling pressure was intense and sustained. The market quickly plunged, triggering a Level 1 circuit breaker approximately 15 minutes into trading, halting all trading for 15 minutes. This pause, intended to calm the market, offered only a brief reprieve. Upon resumption, the selling intensified, pushing prices relentlessly lower throughout the session. The day concluded near its absolute lows, cementing its place as one of the worst trading days in decades.
