Trend Following

intermediate7 min read

Ride the big moves, accept many small losses. The strategy behind most lasting fortunes.

Trend following is exactly what it sounds like: identify an established trend and ride it, staying in the position as long as the trend persists, and exiting when it clearly breaks. “The trend is your friend.” It’s the strategy behind many of history’s great trading fortunes.

The counter-intuitive heart of trend following is that you win small most of the time and win big rarely — and the rare big wins pay for everything. Most trends fizzle, so you take many small losses; but the occasional monster trend runs far enough to dwarf all those losses combined. This means trend followers have a *low win rate (often well under 50%) and still make money — because their winners are much larger than their losers. It demands the discipline to cut losers fast and, harder still, to let winners run* long past where it feels comfortable.

Cut losses short — when a trade doesn’t trend, exit quickly and cheaply. Small losses are the cost of doing business.
Let winners run — resist the urge to book profits early; the whole edge lives in the few trades that run for a long time.
Define the trend objectively — use structure (higher highs/lows), moving averages, or breakouts to enter and to know when the trend has ended.

Common mistakeTaking profits early to “lock in gains,” then sitting through the full loss on losers — the exact opposite of the strategy. Cutting your winners and nursing your losers turns a winning approach into a losing one. The edge is the asymmetry; protect it.

ExampleOver 10 trades a trend follower takes 7 small losses of ₹1 each (−₹7) and 3 winners — but one of those runs huge for +₹20. Net: +₹13, despite winning only 30% of the time. The single big trend paid for all the small losses and then some.

Key takeawayTrend following rides established trends: cut losses short, let winners run. It wins small often, big rarely — a low win rate is fine because the few large winners dwarf the many small losses. The discipline to let winners run is the whole edge.

FAQs

How can a strategy with under 50% wins be profitable?

Because profitability depends on *win rate × average win vs loss rate × average loss*, not win rate alone. If your winners are far bigger than your losers (high reward-to-risk), you can win a minority of trades and still come out well ahead. Trend following is the classic example of this asymmetry.
