Trend Following

Quick answer: Trend Following is a futures approach that assumes returns are autocorrelated — that a move already underway is more likely to continue than to reverse — so it holds long in rising markets and short in falling ones until the trend turns.

In simple words

Trend following is the idea that when a market has been going up, it is a little more likely to keep going up than to suddenly fall, and the same downward. So the trader buys strength and sells weakness, then holds on. The catch is that markets do not trend most of the time; they chop sideways. During those stretches this approach loses small amounts again and again, and the trader only makes the money back on the rare big move. Sitting through the losing stretch is the hard part, and most people quit right before the payoff.

What it looks like

Professional explanation

The assumption underneath everything

Trend following rests on one empirical claim: that returns are positively autocorrelated over the chosen horizon — a rising market tends to keep rising. Nothing in the method proves this is true today; it is a bet on a market regime. When the regime holds, the position captures a large slice of a sustained move. When it does not hold, the same rules generate a long string of small losses. No indicator, moving average or breakout filter can tell you in advance which regime you are in. That uncertainty is not a flaw to be engineered away; it is the permanent condition under which the approach operates.

Why the return profile is positively skewed

A trend follower loses a little most of the time and wins a lot rarely. The many small losses come from entering moves that fizzle; the few large wins come from the occasional move that runs far further than anyone expected. Mathematically the distribution has a long right tail — positive skew. This is the mirror image of premium-selling and mean-reversion, which win often and lose rarely but severely. The consequence is psychological: a positively skewed method feels like losing even when it is working, because the losses are frequent and the wins are unpredictable in timing.

Whipsaw, and why it is the design, not the defect

When price oscillates in a range, a trend follower buys near the top of each swing and sells near the bottom, bleeding on both sides — the pattern traders call whipsaw. It is tempting to add filters to avoid it, but every filter that suppresses whipsaw also delays entry into the real trend that eventually pays for all the whipsaw. There is no free removal of the small losses; they are the price of admission to the large wins. A method that never whipsaws is a method that never catches a trend early.

The rollover cost that options do not have

Because NIFTY and BANKNIFTY futures are cash-settled and expire, a position held for months must be rolled from the expiring contract into the next one, repeatedly. Each roll crosses a bid-ask spread and pays the calendar difference between the two contracts. Over a multi-month trend these roll costs accumulate and quietly reduce the captured move. This is a structural drag specific to holding futures for the long horizons trend following favours, and it is why the horizon and the instrument have to be considered together rather than separately.

Construction

1. Identify that a market is in a directional regime rather than a range — accepting that this identification is inherently uncertain and only confirmable in hindsight.
2. Take a futures position in the direction of the established move: long in a rising market, short in a falling one.
3. Define in advance the adverse level at which the thesis is considered wrong, understanding that this stop is an instruction the market can gap past, not a structural floor.
4. Hold the position while the trend persists rather than taking profit at a fixed target, since the method's edge lives entirely in the rare extended move.
5. Roll the contract to the next expiry to maintain exposure across the trend's life, paying the roll spread each time.

Market outlook

A trader may study trend following when they suspect a market is entering a period of persistent directional movement — after a decisive macro shift, a change in policy stance, or a sustained flow imbalance. The approach assumes returns cluster in one direction for long enough to overcome the small losses accumulated while waiting. It is invalidated the moment the market reverts to oscillating around a level, because that regime turns every entry into a small loss. Crucially, the transition between the two regimes is only visible after it has happened, so no entry condition can promise the trend is real.

Risk profile

Trend following carries undefined risk. A futures position has no long option leg capping the loss; the only structural bound is the underlying reaching zero for a long, or nothing at all for a short. The stop-loss a trader places is an intention, not a structure — on Indian indices, overnight gaps on global cues regularly open past the stop, so the realised loss can exceed the planned one. Because the method deliberately runs positions through counter-moves, individual losses are contained by discipline rather than by structure, and a single gap through the stop during a losing string can undo many prior small wins.

Reward profile

The reward is one-sided and lumpy: a small number of large gains drawn from the occasional move that runs far. There is no cap on the favourable direction — a long can rise indefinitely, a short can fall to a floor — so the upside per trade is open-ended in principle and bounded in practice only by when the trader exits. Because these large wins are rare and unpredictable in timing, the equity curve spends long periods flat or drifting down between them, and the entire positive expectancy, if any exists, is concentrated in a handful of trades.

Margin requirement

A futures position is held against SPAN plus exposure margin, marked to market every day. There is no spread benefit because there is no offsetting leg — the full naked-futures margin applies. An adverse daily move debits the account and can trigger a margin call; on a shortfall the broker may square off the position, sometimes at a worse level than the trader's own stop. SPAN and exposure percentages, and lot sizes, are revised by the exchange and clearing corporation periodically.

Greeks exposure

Volatility impact

Implied volatility is an options concept and does not apply to a futures position — there is no vega, so a change in the option market's expected-move pricing does not move a futures price by itself. What matters to a trend follower is realised volatility: higher realised volatility means larger daily marks in both directions, wider stops, and bigger gaps through those stops. So while the 'IV regime' field is not meaningful for futures, the volatility environment still matters enormously, just through the size of actual price swings rather than through any premium the trader pays or receives.

Time decay

There is no time decay. A futures position carries no theta, so holding it costs nothing in the way a long option does — the value does not erode as expiry approaches. This is the single sharpest contrast with options and the reason trend following is naturally expressed in futures: the method needs to hold through long, uncertain stretches, and an instrument that bled a little every day would make that holding period ruinously expensive. The only time-related cost is the roll spread paid when moving to the next contract.

Practical examples

Lot sizes used above (NIFTY 75, BANKNIFTY 30) are those in force at the time of writing; NSE revises them periodically. Figures exclude brokerage, STT, exchange charges, stamp duty and GST, all of which materially affect small spreads.

Common mistakes

• Abandoning the method during the string of small losses — which is exactly when it is behaving as designed — and so missing the rare large trend that the small losses were paying for.
• Adding filters to eliminate whipsaw without realising that every such filter also delays entry into the genuine trend, trading a visible small loss for an invisible larger missed gain.
• Treating the stop-loss as a certain exit price and sizing the position as if the worst case were the stop level, when an overnight gap can open well past it.
• Taking profit at a fixed target, which caps the rare large win that the entire positive skew depends on and leaves the frequent small losses uncompensated.
• Ignoring accumulated roll costs on a multi-month hold, so the captured move on paper is meaningfully larger than the money actually banked.
• Sizing off the notional's apparent affordability rather than the daily mark-to-market swing, then facing a margin call on a normal adverse day.
• Switching instruments or timeframes after a losing stretch, which resets the sample and guarantees the trader is never present for the payoff on any single market.

Advantages & disadvantages

Adjustments & exits

• A trader may scale into a position as the trend confirms rather than committing full size at once, which reduces the loss on a false start but also reduces participation if the move runs immediately.
• A trader may trail the adverse level upward as an unrealised gain grows, locking in part of a move at the cost of being shaken out by a normal counter-swing that the trend later resumes.
• A trader may roll early, before expiry-week liquidity thins, accepting a possibly worse calendar spread in exchange for avoiding the wider spreads and gaps common in the final sessions.

Adjustment is a decision about risk, not a way to rescue a losing view. See Adjustments and Exit Planning.

Professional usage

Managed-futures and CTA funds run trend following systematically across dozens of global markets at once, precisely because diversification across many uncorrelated trends smooths the lumpy single-market return profile that a retail trader on one index cannot smooth. They also finance and cross-margin positions in ways a retail account cannot, and they hold through drawdowns that would breach an individual's pain threshold or margin. The concept is replicable by retail on a single index; the diversification that makes it tolerable is largely not, which is why a retail trend follower feels the positive skew far more acutely than a fund does.
