Is market fear persistent? : a long-memory analysis
Caporale, Guglielmo Maria; Gil-Alaña, Luis A.; … - 2017
This paper investigates the degree of persistence of market fear. Specifically, two different long-memory approaches (R/S analysis with the Hurst exponent method and fractional integration) are used to analyse persistence of the VIX index over the sample period 2004-2016, as well as some...
