Selling stocks at the right time is just as crucial as buying them. While many investors focus heavily on entry points, few give enough attention to exit strategies. One proven method that has stood the test of time is the 20%-25% profit-taking strategy, a disciplined approach designed to lock in gains before market momentum shifts.
This article explores how this strategy works, why it’s effective, and how you can apply it in real-world trading scenarios—helping you avoid the emotional pitfalls that often lead to missed profits or unexpected losses.

Why Profit-Taking Matters
In the stock market, making money isn’t the hardest part—keeping it is. Without a clear exit plan, even winning trades can turn into break-even or losing positions due to sudden reversals.
Profit-taking, also known as profit protection, is the practice of selling a stock once it reaches a predetermined gain level. Its primary goal? To secure profits before a potential downturn erases them.
Consider this example: Cici, an active trader, identified Netflix (NFLX) as a strong buy after spotting a breakout from a rectangular consolidation pattern. She entered the trade at $263 per share. Over the next few days, the stock climbed to $305.60—an impressive 16% gain. Excited by the upward momentum, she held on, expecting further upside.
But the rally stalled. A sharp eight-day decline followed, wiping out all her gains and pushing the stock below her entry point. Fearing further losses, she finally sold at $255—locking in a 3% loss instead of the 16% profit she once had.
This scenario highlights a common mistake: letting emotions override discipline. Had Cici used a structured profit-taking strategy, she could have exited near her peak and preserved most of her gains.
What Is the 20%-25% Profit-Taking Strategy?
The 20%-25% profit-taking strategy is a rule-based method popularized by William O’Neil, founder of Investor’s Business Daily and author of How to Make Money in Stocks. The core idea is simple:
When a stock rises 20% to 25% from its ideal buy point, consider selling to lock in profits.
This “ideal buy point” refers to the optimal price at which a stock breaks out of a sound technical pattern—such as a cup-with-handle, double bottom, or flat base—on strong volume.
For instance:
- If a stock’s ideal buy point is $100,
- Then the target sell zone becomes $120 to $125.
Once the price hits this range, it’s time to evaluate an exit.
Advantages
- Reduces emotional decision-making: Removes guesswork and keeps discipline intact.
- Easy to implement: Requires only basic calculations and chart analysis.
- High success rate: Historically, many breakout stocks experience pullbacks after a 20%-25% move.
Limitations
- May miss extended rallies: Some high-growth stocks continue rising well beyond 25%, leading to opportunity cost.
- Not one-size-fits-all: Works best with growth stocks exhibiting strong momentum, not value or dividend-focused equities.
Despite its limitations, this strategy offers a reliable framework for short-to-medium-term traders who want consistent returns without overexposure to volatility.

Why 20% to 25%? The Data Behind the Rule
William O’Neil’s research analyzed decades of market data and found a recurring pattern: most significant stock breakouts deliver gains within the 20%-25% range before entering correction or consolidation phases.
This doesn’t mean stocks can’t go higher—but statistically, the odds of a sharp reversal increase significantly after this threshold. By exiting near this zone, investors protect their capital and free up funds to reinvest in new opportunities.
Think of it like compounding: locking in 20%-25% gains across multiple trades allows you to grow your portfolio steadily over time—even if you occasionally leave some upside on the table.
Moreover, this strategy aligns well with institutional buying behavior. When big players accumulate shares during a breakout, they often take profits around this range, triggering short-term selling pressure.
How to Apply It in Real Trading
Applying the 20%-25% rule requires distinguishing between two key concepts:
- Ideal Buy Point: The technically optimal entry based on chart patterns.
- Actual Buy Price: The price you actually paid, which may differ due to slippage or delayed execution.
Let’s revisit Cici’s Netflix trade:
- Ideal buy point: $252 (top of the rectangular base)
- Actual buy price: $263
- 20%-25% target zone: $302.40 – $315 ($252 × 1.20 to $252 × 1.25)
Even though Cici bought at $263, her profit target remains tied to the *ideal* buy point. If she had followed the strategy, she would have sold near $302—achieving a 14.8% return on her actual investment.
This distinction is critical. Basing targets on actual cost basis ($263 × 1.20 = $315.60) could delay the exit too long, increasing risk.
Practical Tips
- Mark your target zone in advance on your chart.
- Set price alerts or conditional orders to notify you when the target is reached.
- Monitor volume and momentum—if buying interest weakens near the target, consider exiting sooner.
What If the Stock Keeps Rising After You Sell?
A common concern: What if I sell at 25%, and then the stock doubles?
That’s where position management comes in.
Instead of selling everything at once, consider:
- Selling 50%-70% at the 20%-25% target to lock in core profits.
- Letting the remainder ride with a trailing stop-loss to capture potential extended moves.
This hybrid approach balances discipline with flexibility—protecting gains while staying open to outlier winners.
Your decision should also reflect your investor profile:
- Trend or swing traders: Should prioritize strict exit rules.
- Long-term investors: Might hold through volatility if fundamentals remain strong.
As Warren Buffett says: “The stock market is designed to transfer money from the active to the patient.” But for most retail investors, patience without a plan often leads to regret.
Frequently Asked Questions (FAQ)
Q: Can I adjust the 20%-25% range based on market conditions?
A: Yes. In strong bull markets, some traders extend the target to 30%. However, always assess volume and resistance levels before doing so.
Q: Should I always sell 100% at the target?
A: Not necessarily. Many traders use partial profit-taking—sell half at 20%-25%, then trail the rest with a stop-loss.
Q: Does this strategy work for all types of stocks?
A: It works best with momentum-driven growth stocks post-breakout. It's less effective for slow-moving value stocks or dividend payers.
Q: What if the stock never reaches 20% gain?
A: Combine this strategy with a 7%-10% stop-loss to manage downside risk and maintain portfolio discipline.
Q: How do I identify the ideal buy point?
A: Look for technical patterns like cup-with-handle, double bottoms, or ascending bases. The breakout point on high volume is typically your ideal entry.
Q: Is this strategy suitable for beginners?
A: Absolutely. Its simplicity and clarity make it ideal for new traders learning disciplined exits.

Final Thoughts
Knowing when to sell is one of the most challenging aspects of investing—but it doesn’t have to be guesswork. The 20%-25% profit-taking strategy offers a data-backed, systematic way to lock in gains and avoid giving back profits during market pullbacks.
While no strategy guarantees perfection, this method increases your odds of consistent success by removing emotion and focusing on historical patterns.
Remember: great investing isn’t about catching every last dollar of a rally—it’s about preserving capital, compounding returns, and staying in the game for the long run.
