“…Table 3 2 reflects the time-frequency spillover effects at different frequencies of absolute returns derived by wavelet frequency decomposition. The trading frequencies are divided into four frequency bands: 2-4 days, 4-8 days, 8-16 days, and 16-32 days, which correspond to short term trading, short-medium term trading, medium term trading, and long term trading, respectively (Mensi et al, 2021a;Miao et al, 2022). The construct of the total spillover changes significantly as they correspond to 28.35, 29.71, 34.87, and 42.88%.…”
