In technical analysis, trend following is a trading strategy that aims to buy a position when a stock or other asset is trending up and sell or sell short a position when an asset is trending down. Some practitioners of trend following may choose to maintain an active position at all times in the market, whether it’s long or short, while others may go long (or long and short) only when a trend has been confirmed.

Because trends are difficult to predict and often can be confirmed only after the fact, many trend-following systems speculate or evaluate trends based on certain principles or calculations that may have a record of historical accuracy. For example, some trends may be determined by trendlines, larger price swings, moving averages, or various indicator readings. The biggest risk in trend following occurs when a price is fluctuating within a trading range. In a trading range (also called a “sideways” market), price will fluctuate between a relative support and resistance level, going up and down over a prolonged period of time but with no clear direction.

Trend followers attempting to buy and sell an asset that’s fluctuating within a range risk taking losses every time price reverses. This is known among traders as getting “whipsawed.” There are times when trends may occur infrequently, but the rationale behind most trend-following strategies is that capturing a long trend will often make up for the smaller losses that might occur during nontrending (whipsaw) periods.

As trend followers like to say: “The trend is your friend, until the end of the trend.”
