These lags make it tough to catch the bounce. If you remember back in the October rally, in the NFP day, the market took a beating right after the NFP number, it tanked for like 1 hour pre-market. Then it tanked and stayed in a range for another hour after the open. Then after 2 hours of this nonsense, it proceeded to rally for the rest of the day and then for weeks. Anyone using the initial market reaction to determine their bias would have gotten the wrong signal
