Une mesure de la persistance dans les indices boursiers
AbstractWe identify and examine the presence of the long memory in equity returns and more generally in specific transformations of these returns, on both the US and European stock markets. Taking into account the persistence phenomenon, we analyze the effect of the splitting of the sample period on the one hand, and the impact of the aggregation on the other hand, on the long me-mory process. Our main results show the strongest evidence of long memory presence in the absolute value of the returns.
