The price trend of any security is more likely to continue than it is to reverse itself. Nevertheless, it will reverse itself someday. Investing in a security based on its price trend is called momentum investing. Momentum investors buy securities that have had high returns over the past year or so and sell those that have had poor returns.
With no guarantees, momentum investing can outperform the buy and hold strategy which we promote. However, it does require ongoing monitoring with the associated major time commitment.
