If there is no Real interest in the stock, the price will then collapse back down to where it was a few minutes earlier.
Does anyone know if this same idea applies to NASDAQ stocks?
You have to remember that there is no centralized marketplace for the Nasdaq, so there cannot be any way of the same thing happening. By reading the NYSE tape, you can usually get involved when you see the Specialist getting ready to do a "print" at a price away from the current market. This technique will alert you to the times when stops are going to be triggered.
We don't recommend that our traders use stops, rather we rely on alerts or other triggers to let us know when a stock hits a breakout or breakdown level. This way we can take into consideration other market data to determine if want to get involved.
