The COVID crash

near the end of it · 2020-02-19 → 2020-03-23, -33.92% over the whole period

What happened that day?

  • Sunday 15 March 2020 — the Fed held an emergency meeting, cut rates to effectively zero, and announced large-scale asset purchases
  • Normally that lifts stocks. Instead the S&P 500 fell 11.98% the next day
  • Markets read it not as support but as a signal: if the Fed is meeting on a weekend, things are far worse than we thought
  • Over that same weekend, countries were starting to close borders and lock down cities
  • Defining feature was speed. From the 19 February record high to the 23 March bottom, it lost 33.92% in a little over a month (far faster than 1987 or 2008)
  • Recovery was equally fast — with sustained stimulus, the index regained its high by August that year
