Momentum investing is essentially an exception to the idea of "buying low and selling high." Investors following this style of investing are usually not interested in betting on cheap stocks and waiting long for them to recover. Instead, they believe that "buying high and selling higher" is the way to make far more money in lesser time.

Everyone likes betting on fast-moving trending stocks, but it isn't easy to determine the right entry point. These stocks often lose momentum when their future growth potential fails to justify their swelled-up valuation. In that phase, investors find themselves invested in shares that have limited to no upside or even a downside. So, betting on a stock just by looking at the traditional momentum parameters could be risky at times.
