I've many times seen whenever, any stock, commodity etc. Gives aggressive move out of no where in the later stages of a rally i.e most bullish bar in the end stages of a upmove and most bearish bar or move in the end stages of of a downward move Always reverses the previous trend.
Remember the 23 March move?
Check it in % terms. One of the biggest day loss in % terms in later stages of rally.
