Secondly, what I've learned is a stock can stay in overbought territory for an elongated period of time but the visits to oversold territory are "usually" brief in "most" cases, obviously there can be exceptions to everything. Think about it this way...the number of new buyers of a stock can be endless and keep price overbought indefinitely. The number of sellers of a stock is a finite number.
