The day the calm-market bet blew up

single-day change vs previous close

What happened that day?

  • On 5 February 2018 the S&P 500 fell 4.1%
  • A US wage growth report days earlier set it off — if prices rise, rates rise, and the market did that arithmetic
  • Then one product lit the fire. Listed products that paid off while markets stayed calm had become popular
  • When markets moved, those products had to sell all at once to cover their losses. The fall fed the selling and the selling fed the fall
  • The fear gauge (VIX) more than doubled in a day. One of the best-known products was wound up and ceased to exist
  • The Dow fell 1,175 points that day — the largest point drop at the time
  • From the peak the index was down 10.16%, and took half a year to get back
