Momentum was gone and the stock drifts lower on low volume. Your momentum stock, which you thought had great fundamentals, becomes what we call a long term hold. To a pure momentum trader it is a loss or dead money which should be moved into another stock. Momentum traders understand there are always sellers in a stock but not always buyers. When momentum stops he sells.
Momentum traders look for volume signals to buy and sell.
If it is not going down, buy. If it is not going up, sell. Chances are the next few days the volume will dry up and the stock will sell off. Let us face it all that stock had to come from somewhere. If you know of something in the works like an upcoming drill program these are all signs to buy and hold.
