What Is Momentum Trading?
Momentum trading is based on the idea of "buying high and selling higher".
Momentum trading seeks to capitalize on the directional price trends of financial assets.
Momentum trading works better in a bull market, as investors tend to herd more.
Understanding momentum trading
Momentum trading is a strategy of buying and selling financial assets according to the recent strength of price trends.
Momentum traders seek to capitalize on the directional trends in a stock price, either upward or downward.
They open a position to take advantage of the expected price change and close the position when the trend starts losing its strength. For example, if a stock surges after reporting strong earnings, a momentum trader could acquire shares and ride the stock’s price upward.
In a word, momentum trading is all about trading with the trend.
Momentum trading is based on the idea that if there is enough force behind a price move, it will continue to move in the same direction.
When an asset reaches a higher price, it usually attracts more attention from investors, pushing the market price even higher. The price increase continues until a large number of sellers enter the market. Once enough sellers are in the market, the momentum changes direction and lowers an asset's price.
History of momentum trading
Researchers have identified persistent momentum trends in stock markets as far back as the Victorian Era (ca. the1830s to 1900).
Richard Driehaus, often considered by many as the father of momentum trading, he gained his prominence by popularizing the strategy. He took the practice and made it into a strategy to run his funds Driehaus believes more money could be earned by "buying high and selling higher" than by buying underpriced stocks and waiting for the market to re-evaluate them.

In the late 2000s, with the rapid development of computers and networking, computer-driven models made it possible for many more sub-variants of momentum trading to be deployed in the real markets.
Disadvantages of momentum trading
When appropriately executed, momentum trading could turn a high profit over a short period of time. However, like any other trading style, some risks come with momentum trading.
Momentum trading is highly time-sensitive. Traders have to keep monitoring the market regularly as the price can fluctuate quite a few multiple times in a day. If the entry position is taken too late, the investment might turn out to be a loss.
Momentum trading is more suitable for a bull market where herding behaviors and price bubbles are quite common. However, in a volatile bear market, the investors should be cautious, which results in a shrinking margin for profit on momentum investing.
