What is Momentum?

Momentum is the rate at which an underlying asset’s price and volume accelerate, either positively or negatively. Once an asset begins to gather momentum it is considered increasingly likely that it will continue to move in the same direction. In technical analysis indicators of momentum are called oscillators and are used to indicate emerging trends.
