Temporal structure and gain/loss asymmetry for real and artificial stock indices
Temporal structure gain/loss asymmetry mutual information
2010/11/1
We demonstrate that the gain/loss asymmetry observed for stock indices vanishes if the temporal dependence structure is destroyed by scrambling the time series. We also show that an artificial index c...
