Greed
Learn how greed changes exits, leverage and portfolio exposure, and how predefined profit-taking and risk caps prevent winning periods from becoming risk escalation.

Greed in trading is the tendency to demand more profit, exposure or action after the original trade objective has already been met or when risk is being understated because recent outcomes feel easy.
Learning objectives
- Recognise greed as process drift rather than simply wanting profit.
- Understand how open profit can change risk perception.
- Use exit rules, exposure caps and R-based accounting to prevent uncontrolled escalation.
What it is
Wanting profit is normal. Greed becomes a trading problem when the desire for additional gain overrides previously chosen constraints. Examples include cancelling a target, adding size without a new setup, refusing to take planned partial profits or raising leverage after a winning streak.
Open profit can create a house-money effect in which unrealised gains are treated as less valuable than starting capital. Economically, however, current equity is still capital at risk. A pound of open profit can be lost just as easily as a pound of initial capital.
Greed also appears at portfolio level when several correlated positions are added because each individually looks attractive. The trader experiences each as a separate opportunity while total beta, collateral usage and liquidation risk become increasingly concentrated.
How greed changes risk
Positive outcomes increase confidence, which can be useful until confidence becomes certainty. The trader begins to interpret normal pullbacks as opportunities to add and stops considering what evidence would invalidate the thesis.
Anchoring to a larger hypothetical profit creates dissatisfaction with a valid realised gain. A trade that reached its planned target may be judged as a mistake if price later moved further, encouraging future rule-breaking.
Leverage magnifies this effect because modest price reversals can create large P&L changes. A trader who increases leverage after success can convert a normal reversal into a portfolio-level drawdown.
Precommitted exit logic reduces bargaining with the market. The trader can still use trailing exits or partial profits, but those mechanisms should be part of the strategy rather than invented only after a large open gain becomes visible.
Control framework
| Check | Purpose | What to verify |
|---|---|---|
| Exit rule | Protects original trade design | State target, trailing method or scale-out logic before entry. |
| Open risk | Prevents house-money thinking | Track current equity and loss from current price to stop, not only entry P&L. |
| Portfolio exposure | Finds hidden concentration | Aggregate correlated positions, gross exposure and collateral usage. |
| Winning-streak behaviour | Detects escalation | Compare size, leverage and trade frequency with the baseline plan. |
Worked example and thought exercise
A trader risks £500 to target 2R, or £1,000. When price reaches the target, they cancel the exit because momentum feels strong and move the stop so far away that £700 of open profit can now be lost.
The decision is no longer the original 2R trade; it is a new risk decision made under the influence of visible profit. If the tested plan instead says take half at 2R and trail the remainder by a defined method, continued participation is disciplined because the additional risk was precommitted.
Thought exercise: why can a profitable trade become a poor decision after entry even if it ultimately makes more money?
Common mistakes and practical workflow
- Treating unrealised profit as expendable money.
- Increasing leverage simply because recent trades won.
- Moving targets without a tested trailing or scaling rule.
- Ignoring correlation when adding multiple positions in the same theme.
Practical workflow
- Define exit and scaling logic before entry.
- Measure current portfolio risk after every material add.
- Use fixed exposure and leverage caps that do not automatically rise after wins.
- Record discretionary extensions of targets or cancelled exits.
- Review whether extra profit from rule-breaking compensates for the larger tail losses it creates across a sample.

FAQs
❓ Is letting winners run greedy?
Not if the strategy uses a defined trailing or trend-following exit.
❓ Why do winning streaks increase risk?
They can create overconfidence and encourage larger size or weaker selectivity.
❓ Should targets never be changed?
They can be adjusted if the process explicitly allows it and the new decision has defined risk.
❓ What is the house-money effect?
It is the tendency to treat recent gains as less valuable and therefore take more risk with them.
Summary
Greed is controlled by treating current equity as real capital, defining exits in advance and preventing recent success from silently changing exposure, leverage or selection standards.
