The 1% Rule: How Jan and Anna Manage Their Market Stall
Meet Jan and Anna
Jan and Anna decide to open a market stall selling handmade jewelry. They start with a total budget of ten thousand euros. This is their entire savings. If they lose it all, they cannot continue their business.
Before buying their first batch of inventory, they sit down and ask: how much can we risk on a single product?
The Inventory Problem
Jan wants to buy one hundred necklaces at one hundred euros each. That would cost ten thousand euros, their entire budget. Anna stops him: what if those necklaces do not sell? We lose everything.
Instead, Anna suggests: let us only risk one percent of our budget on any single product. One percent of ten thousand euros is one hundred euros. This way, if one product fails completely, we only lose one hundred euros, not our entire business.
How This Applies to Trading
Your trading account is exactly like Jan and Anna’s budget. If you have ten thousand euros, risking one percent means you can only lose one hundred euros on any single trade.
The Calculation Step by Step
Let us say you have a five thousand euro trading account.
Step one: Calculate one percent of your account Five thousand euros multiplied by zero point zero one equals fifty euros. Your maximum risk per trade is fifty euros.
Step two: You want to buy shares at twenty euros each with a stop at eighteen euros If wrong, you lose two euros per share (twenty minus eighteen equals two).
Step three: Calculate how many shares you can buy Fifty euros divided by two euros per share equals twenty-five shares. You can buy exactly twenty-five shares.
Step four: Verify the math Twenty-five shares times two euros risk equals fifty euros total risk. This is exactly one percent of your five thousand euro account.
Why One Percent Keeps You in the Game
If Jan and Anna risk only one percent per product, they can survive one hundred failed products before going bankrupt. In reality, some products will sell well, some will fail. The small losses on failures are covered by the profits on successes.
Same in trading: with one percent risk, you can have ten losing trades in a row and only be down ten percent. You are still in the game. Risk ten percent per trade, and three losses wipe out thirty percent of your account.
The Stop Limit: Anna’s Safety Net for Every Purchase
Anna’s Smart Rule
Anna makes a rule for their market stall: before we buy any product, we must decide the lowest price we will accept if it does not sell. If a necklace costs us fifty euros, we agree in advance: if we cannot sell it for at least forty euros within two weeks, we sell it at whatever price we can get and move on.
This predetermined exit point is exactly what a stop limit does in trading.
What Is a Stop Limit?
A stop limit is a price you decide before entering a trade. If the price drops to this level, you automatically sell. No emotions, no hoping it will recover. You accept a small loss and protect your capital for the next opportunity.
Real Example with Jan’s First Stock Trade
Jan wants to buy shares of a technology company.
The setup:
- Current price: fifty euros per share
- Jan believes it will rise to sixty euros
- Jan’s account: two thousand euros
- Maximum risk (one percent): twenty euros
Choosing the stop limit: Jan looks at the chart and sees that the price has bounced from forty-eight euros three times. This is a support level. Jan places his stop at forty-seven euros, just below support.
Calculating position size:
- Risk per share: fifty euros minus forty-seven euros equals three euros
- Maximum risk: twenty euros
- Shares to buy: twenty euros divided by three euros equals six point six shares
- Jan buys six shares (rounded down for safety)
Verification: Six shares times three euros risk equals eighteen euros maximum loss. This is under his twenty euro limit. Perfect.
The Three Types of Stop Limits
Type one: Fixed percentage Always set stop five percent below entry. Simple, works for any stock.
Type two: Technical stop Set stop just below support level. More logical, adjusts to each stock’s behavior.
Type three: Volatility stop Measure how much the stock normally moves daily. Set stop outside this normal range.
Anna’s Wisdom
Anna tells Jan: setting a stop limit is not admitting defeat. It is planning for survival. The market will still be here tomorrow, but only if we protect our capital today.
Risk Versus Reward: The Balance Every Trader Needs
The Market Stall Pricing Decision
Jan finds a supplier offering silver rings for twenty euros each. He needs to decide: what price should I sell them for?
If he sells at twenty-two euros, he makes two euros profit. But if the rings do not sell and he must discount them, he might sell at fifteen euros, losing five euros.
This means he risks five euros to potentially make two euros. That is a terrible deal. He would need to sell more than twice as many rings just to break even with the occasional failure.
The Two to One Rule
Anna teaches Jan: never enter a deal where you can lose more than you can gain. Ideally, aim to gain at least twice what you risk.
Good deal: Risk five euros to potentially make ten euros or more (two to one ratio) Bad deal: Risk five euros to potentially make two euros (zero point four to one ratio)
How This Works in Trading
Let us walk through Marie’s first trade using proper risk to reward.
Marie’s analysis:
- Stock price: one hundred euros
- Support level: ninety-five euros (stop goes here)
- Resistance level: one hundred fifteen euros (target goes here)
Calculating the ratio:
- Risk: one hundred euros minus ninety-five euros equals five euros per share
- Reward: one hundred fifteen euros minus one hundred euros equals fifteen euros per share
- Ratio: fifteen divided by five equals three
- This is a three to one ratio. Excellent.
Position sizing:
- Marie’s account: ten thousand euros
- One percent risk: one hundred euros
- Shares to buy: one hundred euros divided by five euros equals twenty shares
The outcomes: If wrong: Marie loses twenty shares times five euros equals one hundred euros (one percent of account) If right: Marie gains twenty shares times fifteen euros equals three hundred euros (three percent of account)
The Power of Good Ratios
With a three to one ratio, Marie can be wrong twice and right once, and still break even. In practice, if she wins just forty percent of her trades with three to one ratio:
- Ten trades: four winners, six losers
- Losses: six trades times one hundred euros equals six hundred euros
- Wins: four trades times three hundred euros equals one thousand two hundred euros
- Net profit: six hundred euros
She wins only forty percent but still makes money. This is the power of good risk to reward ratios.
Test Your Knowledge: Risk Management in Practice
Practice Scenario One: Jan’s Position Sizing
Jan has a trading account of eight thousand euros. He wants to buy shares of a retail company priced at forty euros. He plans to set his stop at thirty-eight euros.
Question: How many shares can Jan buy while risking only one percent?
Solution: Step one: Calculate one percent of account Eight thousand euros times zero point zero one equals eighty euros maximum risk.
Step two: Calculate risk per share Forty euros minus thirty-eight euros equals two euros per share.
Step three: Calculate position size Eighty euros divided by two euros equals forty shares.
Answer: Jan can buy forty shares.
Practice Scenario Two: Anna’s Risk to Reward Check
Anna finds a stock at sixty euros. Her analysis shows support at fifty-seven euros and resistance at seventy-two euros.
Question: Should Anna take this trade based on risk to reward?
Solution: Risk: sixty euros minus fifty-seven euros equals three euros Reward: seventy-two euros minus sixty euros equals twelve euros Ratio: twelve divided by three equals four to one
Answer: Yes, this is an excellent four to one ratio. Anna should consider this trade.
Practice Scenario Three: Marie’s Account Protection
Marie has twenty-five thousand euros. She takes five trades, each risking one percent. Three trades hit the stop limit (losses), two trades hit the target with a two to one ratio.
Question: What is Marie’s account balance after these trades?
Solution: Risk per trade: twenty-five thousand times zero point zero one equals two hundred fifty euros Reward per winning trade: two hundred fifty euros times two equals five hundred euros
Losses: three trades times two hundred fifty euros equals seven hundred fifty euros Wins: two trades times five hundred euros equals one thousand euros
Net result: one thousand euros minus seven hundred fifty euros equals plus two hundred fifty euros New balance: twenty-five thousand euros plus two hundred fifty euros equals twenty-five thousand two hundred fifty euros
Answer: Marie ends with twenty-five thousand two hundred fifty euros, a one percent gain despite losing more trades than she won.

- Set your stop limit before you buy, not after
- Only take trades with at least two to one reward to risk
- Small consistent losses are acceptable when your winners are bigger

Frequently asked questions
- What's the most important risk management rule for beginners?
- The 1% Rule: Never risk more than 1% of your account on a single trade. This is non-negotiable and the #1 difference between traders who survive vs. those who blow up. With 1% risk, you can lose 20 trades in a row and still have 82% of your capital left. With 10% risk, just 7 losses in a row wipes out 50% of your account—a death spiral most never recover from. How to apply: (1) Calculate 1% of account, (2) Determine entry and stop prices, (3) Divide risk by stop distance for position size. Your account is your career. Protect it.
- Should I use mental stops or hard stop-loss orders?
- Always use hard stop-loss orders placed with your broker. Mental stops fail 80%+ of the time due to psychology. Price hits your mental stop, you think 'maybe it bounces,' you wait, it drops more, you panic-sell at a worse price. Hard stops eliminate emotion: set at $95, automatically out when hit. No decisions, no emotions. For liquid stocks (AAPL, SPY), hard stops are mandatory. Set your stop the moment you enter, before thinking about profits.
- What's a good risk-reward ratio for beginners?
- Minimum 2:1, but aim for 3:1 as a beginner. At 2:1 with 40% win rate, you're profitable. At 3:1 with 35% win rate, you still profit. This is crucial because beginners typically have 35-45% win rates while learning. Calculate before every trade: (Target - Entry) ÷ (Entry - Stop). Below 2? Skip it. Common mistake: risking $500 to make $300 (0.6:1). You'd need 80% win rate—impossible. Be patient. Great 3:1+ setups appear weekly.
- How many trades can I take at the same time?
- Beginners: 1-3 max. Intermediate: 3-5. Advanced: 5-10. Never more than 10 unless professional. Each position = 1% risk. 10 positions = 10% total risk. Beyond 10, too much simultaneous risk if market crashes. Also attention span—can you seriously track 15 stocks' levels, news, earnings? Most can't. Correlation trap: 8 tech stocks isn't 8 positions, it's 1 leveraged tech bet. Start with 1-2 until you have 6+ months experience. Quality over quantity.
- When should I move my stop loss to break-even?
- Move to break-even only when price moved favorably by at least 2x your initial risk. Entry $100, stop $95 (risk $5). When price hits $110 (+$10, 2x risk), move stop to $100. Why 2x? Moving too early gets you stopped out by normal pullbacks. The 2x rule ensures: (1) You've paid for risk with profit, (2) Trend confirmed, (3) Breathing room for pullbacks. After break-even, use trailing stops. Never let a +5x winner turn into a loss.
