Risk management separates successful traders from those who blow up their accounts. Even traders with excellent analysis skills fail because they neglect risk management. Here are the ten most common mistakes and how to avoid them.
Mistake 1: No Stop Loss
Trading without a stop loss is gambling, not trading. Every position should have a predefined exit point where you admit the trade is wrong.
The Problem
- Small losses become catastrophic losses
- One bad trade can wipe out months of gains
- Emotional attachment to positions grows with losses
The Solution
Before entering any trade, determine your stop loss level based on technical analysis. Place the actual order immediately. No exceptions.
Rule: If you cannot identify where you are wrong, you should not take the trade.
Mistake 2: Risking Too Much Per Trade
Risking 10%, 20%, or more on a single trade is a recipe for disaster. Even a 50% win rate will produce devastating losing streaks.
The Math
At 10% risk per trade:
- 5 consecutive losses = 41% drawdown
- 10 consecutive losses = 65% drawdown
The Solution
Risk 1-2% maximum per trade. This keeps drawdowns manageable even during inevitable losing streaks.
Mistake 3: Moving Stop Losses Further Away
When a trade moves against you, the temptation is to widen the stop to avoid being stopped out. This destroys your entire risk management plan.
The Problem
- Losses become larger than planned
- Position sizing calculations become meaningless
- You are hoping instead of trading
The Solution
Accept that being stopped out is part of trading. If your stop is hit, your analysis was wrong for this trade. Move on.
Mistake 4: Averaging Down on Losers
Adding to a losing position to lower your average cost usually makes things worse. You are doubling down on a position that is already proving you wrong.
When It Goes Wrong
- Buy 100 shares at $50
- Price drops to $40, buy 100 more
- Price drops to $30, buy 100 more
- Now you have 300 shares with massive exposure to a losing trade
The Solution
If you want to add to a position, have a predetermined plan with specific levels. Better yet, add to winners, not losers.
Mistake 5: Ignoring Correlation
Holding multiple highly correlated positions creates hidden concentration risk.
Example
You have "diversified" with positions in Apple, Microsoft, Google, Amazon, and Meta. But these are all big tech stocks that tend to move together. A tech selloff hits all five simultaneously.
The Solution
Consider total exposure to correlated assets as one combined position. Diversify across truly uncorrelated assets, sectors, and strategies.

Mistake 6: Revenge Trading
After a loss, the urge to immediately trade again to "make it back" is powerful. This emotional response almost always leads to more losses.
The Pattern
- Take a loss
- Feel frustrated, want to recover quickly
- Take a bigger or lower-quality trade
- Take another loss
- Spiral continues
The Solution
Implement a mandatory break after losses. Walk away from the screen. The market will be there tomorrow. Never increase size to recover losses faster.
Mistake 7: Not Having Daily/Weekly Loss Limits
Without maximum loss limits, a bad day can become a disaster. Traders often enter a destructive spiral where each loss leads to worse decisions.
Example Rule
- Daily loss limit: 3% of account
- Weekly loss limit: 6% of account
- If hit, stop trading until limit resets
The Solution
Set hard limits and honor them. When you hit your limit, you are done trading until the next period. No exceptions.
Mistake 8: Overleveraging
Leverage amplifies both gains and losses. Excessive leverage turns small adverse moves into account-destroying events.
The Problem
- $50,000 account with $200,000 in positions = 4x leverage
- A 5% adverse move wipes out 20% of your account
- Margin calls force you to close at the worst time
The Solution
Limit leverage to 2x or less. If you are new, avoid leverage entirely until you have proven consistent profitability.
Mistake 9: Ignoring Gap Risk
Stocks can gap significantly overnight or over weekends. Stop losses do not protect you when price opens far beyond your stop level.
High Gap Risk Scenarios
- Holding through earnings announcements
- Biotech stocks awaiting FDA decisions
- Positions over weekends during uncertain times
- Any stock with pending news
The Solution
Reduce position sizes when holding through high-risk events. Use options for defined risk. Or simply avoid holding through binary events.
Mistake 10: Not Tracking and Reviewing
Without tracking your trades, you cannot identify what is working and what is not. You repeat the same mistakes without even realizing it.
What to Track
- Every trade with entry, exit, and size
- Planned vs. actual risk
- Win rate by setup type
- Average winner vs. average loser
- Emotional state during trades
The Solution
Keep a detailed trading journal. Review weekly to identify patterns. Adjust your approach based on data, not feelings.
Risk Management Checklist
Before every trade, verify:
- Do I have a stop loss defined?
- Is my risk less than 2% of my account?
- Have I calculated proper position size?
- How does this affect my total portfolio exposure?
- Am I within my daily loss limit?
- Am I trading emotionally or systematically?
- Is there gap risk I should consider?
Remember: Risk management is not about avoiding losses - losses are inevitable. It is about keeping losses small enough that you can survive long enough for your edge to play out.
Summary
Most trading failures are not due to bad analysis but to poor risk management. Always use stop losses. Risk only 1-2% per trade. Do not move stops or average down. Be aware of correlation and gap risk. Implement daily and weekly loss limits. Avoid revenge trading and overleveraging. Track everything and review regularly. Master these principles, and you will outlast the majority of traders who blow up their accounts through preventable mistakes.
