Trend following is the most enduring and successful trading approach ever documented. It's not flashy. It doesn't involve predicting where price will go. It doesn't require you to catch bottoms or tops. What trend following does is simple: it lets you ride the direction price is already moving, exiting when that direction changes. This remarkably straightforward philosophy has generated wealth for countless traders across decades and markets. If you understand nothing else about trading, understanding trend following will put you ahead of 90% of retail traders.
What is Trend Following and Why It Works
Trend following is the practice of identifying the direction prices are moving and trading in that direction. You buy when price is moving up, you sell when that upward movement shows signs of stopping. You sell short when price is moving down, you cover when that downward movement shows signs of stopping. That's it. The philosophy assumes that prices tend to move in one direction for extended periods before reversing, and that riding those moves is the most reliable way to make money.
Why does this work? There are several reasons. First, trends exist. This isn't debatable—decades of research confirms that financial markets exhibit trending behavior. Not all the time, but often enough that building a strategy around trends is mathematically sound. Second, trends tend to persist. The longer an asset has been moving in one direction, the more likely it will continue moving that way in the near term. This is partly due to momentum, partly due to fundamental reasons driving the move, and partly due to technical factors like moving averages and support/resistance.
Third, trend following aligns you with market dynamics. Instead of fighting what the market is doing, you're cooperating with it. Fourth, trend following lets you use position sizing and compounding. In long-term uptrends, you can hold positions for months or years, allowing compound growth to work in your favour. Fifth, there's an asymmetry in trend following: losing trades tend to be small (you exit quickly when the trend breaks), while winning trades can be enormous (you're riding moves that last weeks or months). This creates positive expected value over time.
The Trend is Your Friend: Trading With the Market's Direction
One of the most important lessons in trading is this: never fight the trend. Fighting a trend is trying to pick the top in an uptrend or the bottom in a downtrend. It feels natural—the market's been up so much, surely it's about to come down. But fighting trends is how traders blow accounts. The trend is your friend because it's self-reinforcing. An uptrend means higher highs and higher lows. When you see those higher highs and lows, that's the market telling you demand is strong.
Consider a stock that's been rallying for three months straight. It's easy to think "this can't go higher, it's overbought." This thought has ended many trading accounts. Instead, trend followers look at that three-month rally and think "this has been working—let me find a good entry in the direction this is already moving." The stock that has been up for three months is likely to continue up for at least one more month, statistically. Not always, but often.
This is where trend following separates itself from counter-trend trading. Counter-trend traders try to be clever and catch reversals. Trend followers are content to miss the first part of moves and catch the middle (the most profitable part) before exiting before the reversal. Over time, the trend follower's approach wins because they're aligned with what the market is actually doing.
Identifying Trends: Higher Highs and Lows, Moving Averages, ADX
To trade trends, you first need to identify them. There are three main ways to do this.
Higher Highs and Higher Lows: This is the purest definition of an uptrend. Look at a chart. In an uptrend, each significant low is higher than the previous low, and each significant high is higher than the previous high. Conversely, in a downtrend, each high is lower than the previous high, and each low is lower than the previous low. This is visual, mechanical, and objective. You don't need anything but the raw price chart.
Moving Averages: The most common way to identify trends is with moving averages. If price is above the 50-day moving average and the 50-day is above the 200-day moving average, you're in an uptrend. If price is below the 50-day and the 50-day is below the 200-day, you're in a downtrend. When the 50-day crosses above the 200-day (the golden cross), that's a trend beginning. When the 50-day crosses below the 200-day (the death cross), that's a trend ending. This is so widely used that it's become a self-fulfilling prophecy—so many traders watch it that it predicts reality.
ADX (Average Directional Index): The ADX is an indicator that measures trend strength. A reading above 25 indicates a strong trend. Above 35 indicates an extremely strong trend. Below 20 indicates a weak trend or range-bound trading. ADX is excellent for confirming that a trend is truly strong before you commit capital. Many trend followers won't enter a trend until the ADX is above 25, confirming that the trend has genuine momentum.
The best approach combines all three. Look at the chart visually—are you seeing higher highs and lows? Check the moving average alignment—is price above the 50, and the 50 above the 200? Check the ADX—is it above 25? If you get "yes" to all three questions, you've got a strong, confirmed uptrend worthy of your trading capital.
Moving Average Crossover Systems: Golden Cross and Death Cross
One of the simplest trend-following systems is based entirely on moving average crossovers. While simple, these systems have been remarkably profitable for long-term traders.
The Golden Cross: This occurs when the 50-day moving average crosses above the 200-day moving average. Historically, this has been a powerful signal for the beginning of an uptrend. When this happens, mechanical traders who follow this system will go long. It doesn't matter if the stock is already up 20%—if the golden cross just happened, they're buying. The philosophy is that the trend is just beginning, and significant moves are ahead.
In reality, not every golden cross leads to a massive uptrend, but statistically they do more often than not. The odds are in your favour, which is all you need in trading. Many major market rallies have begun with a golden cross, making this signal respected across the entire investing world.
The Death Cross: This is when the 50-day moving average crosses below the 200-day moving average. This has been a reliable signal for downtrend beginnings. Mechanical trend followers will initiate short positions or sell all long holdings when the death cross occurs. Over decades of testing, death crosses have preceded significant downtrends more often than not.
The Simplicity and Power: The beauty of this system is that it's mechanical. You don't need to have an opinion about whether a stock should go up or down. You just follow the moving averages. This removes emotion and forces discipline. Some of the most successful trend-following funds use moving average crossovers as their primary entry signal.
Drawback—Whipsaws: In choppy, range-bound markets, moving averages whipsaw you. You get a golden cross, the market rises 2%, then a death cross appears, and suddenly you're short during another rally. These whipsaws are frustrating but part of the cost of trend following. The way to mitigate them is to only trade moving average crosses when the ADX is above 25 (confirming the trend has strength) or to wait for the 50-day to be sufficiently above the 200-day before trading (at least 2% separation).
Trend-Following Entry Methods: Breakout, Pullback, MA Bounce
Once you've identified a trend, you need an entry method. There are several, each suited to different traders.
Breakout Entries: Buy when price breaks above a recent high or resistance level. If a stock has been in an uptrend and consolidates at £3.00 to £3.20 for a few weeks, breaking above £3.20 is a signal to enter. Breakouts often accelerate moves because they trigger stops on short sellers and attract new buyers. The advantage of breakout entries is that they're clean and objective. The disadvantage is that you're entering after a small move has already occurred, and you might be entering at the most expensive part of a move.
Pullback Entries: Enter when price pulls back to a moving average or support level within a trend. If a stock is in a strong uptrend and pulls back to the 20-day EMA, that's an entry. This gives you better entry prices than breakout entries and lower risk—your stop is tighter. The advantage is better risk-reward. The disadvantage is that pullbacks don't always happen. Sometimes in the fastest uptrends, price barely pulls back, and you miss the move while waiting.
Moving Average Bounce: Enter when price bounces off a moving average that it briefly touched. If price touches the 50-day EMA and bounces higher without closing below it, you enter the bounce. This is slightly more aggressive than waiting for a pullback but less aggressive than chasing a breakout. Many traders prefer this approach because it combines some of the benefits of pullback and breakout entries.
Most successful trend followers use a combination of these. They primarily trade pullback entries to maximize risk-reward, but they also take breakout entries when momentum is accelerating, and they might add on MA bounces if they're already in a position and want to pyramid.
Staying in the Trend: Trailing Stops and MA Exits
Entering a trend is only half the battle. The other half is staying in the trend long enough to capture the real profits. Many traders exit too early, taking small profits when they should be holding for large ones.
Trailing Stops: The best tool for staying in a trend is a trailing stop. This is a stop loss that moves higher with price in uptrends and lower with price in downtrends. If you enter a long position at £2.00 and price rises to £2.50, you might set a trailing stop 10p below the current price (£2.40). If price rises to £3.00, the stop trails up to £2.90. The stop only ever moves in your favour, never against it. This allows you to capture large moves while protecting most gains.
The width of your trailing stop depends on your timeframe and the volatility of the asset. For swing trading positions held over weeks, a trailing stop of 5–7% of price is common. For longer-term trend following, it might be 10–15%. The key is that it's loose enough to allow normal pullbacks within the trend without stopping you out, but tight enough to protect most of your gains.
Moving Average Exits: Another approach is to exit when price closes below a moving average that had been supporting the trend. If you're in a long position and the 20-day EMA had been bouncing repeatedly, but price then closes below the 20-day EMA, that's your signal to exit. This is less precise than a trailing stop but more reactive to changing market conditions.
ADX Decline as Exit: When ADX falls below 25, it means the trend is weakening. Many trend followers use this as a partial or full exit signal. They might take profits but keep a small position in case the trend re-accelerates. Or they might exit entirely and wait for the next strong trend to form.
Volatility-Based Stops: Some traders use the Average True Range (ATR) to set stops. If a stock has an ATR of £0.20, they might set a trailing stop 2 ATRs away from price (£0.40). This ensures their stop is appropriately sized for the current volatility of the asset.
Position Sizing in Trend-Following: Pyramiding Winners
One secret that separates good trend followers from great ones is how they size positions. Simple trend following says "enter a trend, hold it, exit it." Great trend following says "enter a trend, add to winners, compound your gains."
Pyramiding: This is adding to a winning position as it moves in your favour. You might initially buy £2000 worth of stock. If price rises and the trend accelerates, you add another £2000. If price makes a new high, you add a third £2000. By the time price has moved 30%, you're holding 3x your original position, but you're holding larger amounts at better price levels.
The key to pyramiding is that each addition should be smaller than the last. Your first entry might be 1 unit, your second 0.75 units, your third 0.5 units. This is called "pyramid up in diminishing quantities." It keeps you from being overly aggressive as the trend extends, which makes sense because old trends are more likely to end than young ones.
Position Sizing for Risk: Before you even think about pyramiding, you need to size your initial position correctly. The rule is: only risk a fixed percentage of your account on each trade—typically 1–2%. If your account is £10,000 and you want to risk £100 per trade, you need to know where your stop loss is. If the stop is 50p away and the stock is at £2.00, you might buy 200 shares (£400 at risk). This ensures that even if you have a streak of losses, you don't blow your account.
Scaling Out of Winners: As profitable trades move in your favour, many trend followers scale out partially. They might sell 50% at their measured target, then hold the remaining 50% with a trailing stop. This locks in profits while keeping upside exposure. It's a middle ground between exiting too early and being too greedy.
Why Trend Following Has Long Losing Streaks
Trend following is profitable over time, but over time means months or years of trading. In between, you'll experience extended periods of losses. This is something you must understand and accept.
Why? Because markets spend a significant portion of time in ranges or choppy consolidations. During these periods, trend-following systems will get whipsawed. You'll get stopped out on one side of the range, then the market will move the opposite direction and you'll get stopped out again. In a choppy month, you might have 3–4 losing trades for every winner.
However—and this is crucial—the winners tend to be much larger than the losers. You might have 5 losses of £500 each and then one winner of £3000. That's a net gain of £2500 over six trades despite having an 83% loss rate. This is the nature of trend following.
Psychologically, this is brutal. It's much easier to stay with a system that wins 70% of the time than one that wins 30% of the time, even if the 30%-win system makes more money. This is why many traders abandon trend-following systems during losing streaks. They don't have the discipline to stick with a system that works in the long term but feels like it's not working in the short term.
Trend Following on UK Stocks and Indices
FTSE 100 Index: The FTSE exhibits clear trends that trend followers can exploit. Major rallies from the 2009 low to 2017 high were textbook uptrends. Recent ranges and consolidations have created choppy conditions, but even within chop there are sub-trends. A trader who followed the FTSE with moving average systems would have been long through the 2009–2017 uptrend, short or neutral through 2015–2016, and long again through much of 2022–2023.
Barclays (BARC): Banking stocks often exhibit strong trends. Barclays had a multi-year downtrend from 2007 to 2009, then a consistent uptrend from 2009 to 2021. Trend followers riding that uptrend saw enormous gains. Even traders who got in late (in 2015) and held until 2021 would have doubled their money.
Unilever (ULVR): Consumer defensive stocks tend to have gentler trends than cyclicals, but they trend nonetheless. Unilever has shown periods of several-year uptrends and downtrends. A trader using moving average signals would have participated in those major moves.
AIM-Listed Smaller Caps: Smaller companies on the Alternative Investment Market tend to exhibit even more pronounced trends than large caps. Because they're less efficiently priced, they can trend for longer periods. Trend followers who focus on AIM stocks often see larger moves than on blue chips, though with greater volatility.
Famous Trend Followers and Their Results
Richard Dennis and the Turtles: In the 1980s, Richard Dennis proved that trend following could be taught. He recruited a group of traders (the "Turtles") and trained them in trend-following methods. Over the next five years, the Turtles returned over 100% annually. Their system was based on breakouts from 20-day and 55-day highs and lows—pure trend following. This remains one of the most famous demonstrations that trend following works.
Paul Tudor Jones: One of the most successful hedge fund managers ever, Tudor Jones made his fortune partly through trend following. He uses a combination of technical analysis and trend identification. His ability to stay with long-term trends has generated returns that have made him a billionaire.
David Harding and Winton Global Alpha: Winton Global Alpha is a trend-following fund that has delivered consistent returns across decades by following trends in global futures markets. Despite long losing streaks (they've had years with losses), the system's long-term record is exceptional because the winners are so large.
Ed Seykota: One of the original trend followers, Seykota built a trading system in the 1970s that turned £5,000 into £15 million. His philosophy was simple: if price breaks above the highest close of the last 50 days, go long. If price breaks below the lowest close of the last 50 days, go short. This was pure trend following.
Key Takeaways
Trend following is the most reliable long-term trading approach because it works with market dynamics instead of against them. Identify trends using three methods: higher highs and lows, moving average alignment, and ADX strength. Use moving average crossovers (golden cross and death cross) as mechanical entry signals. Enter trends via breakouts, pullbacks, or moving average bounces depending on your risk tolerance and entry speed preference. Use trailing stops to stay in winning trends and capture large moves. Scale out of winners and pyramid positions to compound gains. Accept that trend following produces long losing streaks between wins, and stick with your system through these periods because the big winners make up for all the losses. Study how famous trend followers like Dennis, Tudor Jones, and Seykota built fortunes by following simple rules and having discipline. With consistency and patience, trend following will produce steady, compounding wealth.
