peak-to-trough, the whole slide
16 trading days · 2011-02-21 → 2011-03-15
back to the old high on 2013-01-15
What happened that day?
- From the high on 21 February 2011 to the low on 15 March, the Nikkei fell 20.74% in just 16 trading days
- A large earthquake struck off the Tōhoku coast on 11 March and a tsunami came ashore
- Then an accident began at a nuclear power station, and the nature of the problem changed
- Earthquake damage can be counted. Nobody knew how far the nuclear accident would go — the state a market handles worst
- On 15 March alone the index fell more than ten percent, on news that conditions at the plant had worsened
- Power cuts stopped factories, and because component supply chains span the world, production stopped in other countries too
- This high was recovered in January 2013
