From Knight and Pretty (1997) The Impact of Catastrophes on Shareholder Value:
The above graph shows the impact of a crisis on organizations’ shareholder value.
Organizations with effective resilience see an overall increase in their shareholder value and a healthy recovery whereas those who fail to plan and deliver an ineffective response struggle to recover and see a decrease in their shareholder value.
It is assumed that the same market behavior is valid for e.g. customer loyalty and brand value.
