Momentum Trading - Is it a good trading strategy?

The answer depends on what kind of risk return profile this strategy has and whether your temperament matches up to the temperament required in this strategy. So it's important to understand the contours of the Momentum trading style first to make a decision.

Technically momentum is mass times velocity and Physics says that if an object's velocity of movement is accompanied by large mass it will have very high tendency to continue to move in it's direction until and unless a massive force try to stop it or change it's direction. It has been witnessed that the same physics applies to stocks and markets as well. Whatever be the direction, if the movement of the stock is accompanied by larger volume it will have natural tendency to continue to move in that direction.
