Define MOMENTUM of the waves Part - 2

Momentum is the rate of acceleration of a security's price—that is, the speed at which the price is changing. Momentum trading is a strategy that seeks to capitalize on momentum to enter a trend as it is picking up steam. Momentum investing is a trading strategy in which investors buy securities that are rising and sell them when they look to have peaked. The goal is to work with volatility by finding buying opportunities in short-term uptrends and then sell when the securities start to lose momentum.
