single-day change vs previous close

What happened that day?

  • On 26 August 2015 the S&P 500 rose 3.9%
  • A give-back of the Monday crash. The index had fallen 12.35% from its peak in a matter of days
  • China cut both its policy rate and the reserves banks must hold — read as a promise to hold the market up
  • In the US, the president of the New York Fed said the case for a September hike had grown less compelling
  • A durable goods orders report that morning also came in better than expected
  • A sharp jump right after a sharp fall is ordinary. Sellers are already out, so one piece of news moves everyone the other way
  • Getting back to the old high took much longer — not until July 2016
