Abstract
This paper presents extreme value theory and its application to the calculation of the value at risk of a position. This statistical theory allows a quantification of the behavior of extreme price movements. Extreme movements are associated with both tremors like market adjustments or corrections observed during ordinary periods. The approach based on extreme price movements then reconciles the existing methods of calculation of value at risk in usual market conditions and the methods of stress testing focusing on financial crises.
