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.

While not calling it momentum investing, William J O'Neil's acclaimed best-seller How to Make Money in Stocks gives considerable weightage to Relative Price Strength Rating in his CANSLIM formula (the L stands for Leader or Laggard).
Note that O'Neill's Relative Strength is not related to the Technical Analysis RSI indicator. Nor does Momentum Investing have anything to do with the Momentum Indicator. Though it is based on price, Momentum Investing is not part of Technical Analysis.
