Momentum investing is a system of buying stocks or other securities that have had high returns over the past three to twelve months, and selling those that have had poor returns over the same period. ()
Scholarly studies - some going back to the 19th century - have shown that momentum investing has outperformed the market indices comfortably. One of the best known studies was conducted by Narasimhan Jegadeesh and Sheridan Titman in 1993:

If you wish to try momentum investing, you need to build a portfolio of at last momentum 15 stocks to reduce risk with diversification.
