Selling & Holding Winners

Back at Your Entry Doesn’t Automatically Mean Sell.

You buy the breakout. The stock moves higher. Then it pulls back toward your entry.

Suddenly, you’re questioning the entire trade.

Ideally, a stock takes off after you buy and never looks back, but good trades don’t always develop that cleanly.

Mark Minervini discusses this in his explanation of “squats and reversal recoveries.” A breakout can stall, pull back, and still recover. He cautions against abandoning a trade prematurely when the stop remains intact and major technical violations aren’t developing, particularly in a healthy market.

DHT illustrates the broader lesson.

On the chart, price clears the base, advances, then pulls back toward the original breakout area in its first natural reaction. It finds support and resumes moving higher.

That return toward the breakout area didn’t automatically mean the trade had failed.

Depending on your original stop, time horizon, and the stock’s behavior, this may be a situation where you simply follow your plan and allow the reaction to play out.

Minervini describes a natural reaction followed by a recovery to new highs as an opportunity to raise your stop. Once that recovery occurs, moving the stop to breakeven or better may make sense, depending on the structure of the trade.

How far the stock has already moved in your favor matters, too.

A small initial gain pulling back toward your entry is different from surrendering a profit worth several times your original risk.

Minervini also discusses raising stops after gains of roughly two or three times initial risk, particularly when those gains exceed your historical average. Protecting that progress may involve raising your stop or taking some profit into strength, depending on your plan and market conditions.

The distinction is between normal fluctuation and price action that invalidates your setup. Is support holding? Is selling pressure easing? Or are heavy selling and technical violations piling up?

Respect your stop. Respond to genuine deterioration. Give the trade room to develop within the risk you planned.

Your entry price is a reference point. Returning to it is not, by itself, a reason to sell.

+251% Earnings. +1,843% Sales. And a Chart That Doesn't Care.

LQDA is another great reminder of why you should NEVER fall in love with a stock.

Look at these numbers:

• Quarterly EPS growth: +251%

• Quarterly sales growth: +1,843%

• Fund ownership growth: +30.7% in the latest reported quarter

These are the kinds of fundamental numbers we study in the biggest stock market winners of all time.

But look at that chart. Massive selling volume, a complete breakdown through the 50-day and 200-day moving averages, and a stock down over 60% in just one month.

William O'Neil put it perfectly in How to Make Money in Stocks:

"The moral of the story is: never argue with the market."

Explosive earnings and sales don't give you permission to ignore price action, institutional selling, or your exit rules.

You can be absolutely right about a company's fundamentals and still lose a fortune trading its stock.

Fall in love with your process, not your positions.

How to Stay in Big Winners Without Guessing the Top

If you’re a position trader focused on growth and momentum stocks, here’s a practical way to let your winners run while still cutting your losses short.

You finally buy a great stock. You sell for a nice gain. Then you spend the next three months watching it double.

Finding the winner wasn’t the problem. Holding it was.

Mark Minervini and David Ryan discussed two tools that can help you stay with a strong stock through a bigger move.

First: let the 50-day moving average catch up to your entry.

Start with a proper entry and an initial stop based on the setup. If the trade fails, take the loss.

As the stock advances, its 50-day moving average rises. Once that line reaches your entry price or higher, Minervini explains that you can switch to using it as a trailing stop.

He describes this as “breakeven or better.” Your stop reference is now at or above your cost, although a gap below it can still produce a loss.

Minervini particularly likes this approach early in a new bull market, when emerging leaders can run for months while holding their rising 50-day.

The charts attached show how this can work: a defined entry and initial stop, followed by the rising 50-day helping you stay in the move.

Second: watch the weekly lows.

Ryan noticed that many of the great winners he studied rarely made three consecutive weekly lower lows during their strongest advances.

One or two weeks of pullback were common. Three successive lower lows were a warning that selling had become more persistent.

But he wasn’t talking about each week undercutting the previous low by a few cents. The size of the decline and the volume are important.

Meaningful weekly declines on heavier volume, especially alongside a break of the 50-day or the weekly 10-week line, provide stronger evidence that the stock’s behavior is changing.

Minervini combines Ryan’s observation with the moving average to help judge whether to keep holding. A stock that continues to hold its rising average without persistent weekly deterioration may deserve more time.

You don’t wait for three weak weeks if your stop has already been hit. Remember, these tools help manage an established winner, but your initial risk limits still apply.

Also, holding longer means accepting some giveback. A trailing stop won’t get you out at the exact high. You give the stock room to keep advancing, knowing that some profit will come back before you exit.

If you want to catch a bigger move, you have to sit through some pullbacks. Decide what will get you out before the pullback starts.

I cover these methods and other ways to manage trades in Module 5 of the Momentum Trading Strategy Course, available to all paid subscribers.

The Entry Is Simple The Hard Part Is You

Someone asked how I manage fast-moving stocks when timing the entry and knowing when to sell can feel so difficult.

My entry and management tactics are basic: a defined entry, a stop, trailing higher lows, and selling some into strength. There’s nothing revolutionary about them. Knowing the tactics and executing them under pressure are two different skills.

I believe a big part of my improvement comes from staying calm at the entry and throughout the trade. That comes from experience. I’ve made almost every mistake in the book, and a stock moving fast no longer gets me nearly as excited as it once did.

I can sell some while the stock is still climbing without needing to squeeze out every last dollar. I can take a loss without needing to prove I was right. I still feel emotions, but they have much less influence over my decisions.

If a stock runs 150%, I can be perfectly content capturing a 30% gain. I’d rather take a trade with 3–4% initial risk and capture 30% than accept 40% risk trying to capture the entire 150%.

I don’t need the whole move. I need a worthwhile return for the risk I take, and the discipline to execute my plan.

The Biggest Down Day Can Be Your Warning

After a strong advance, one warning sign gets my attention: the biggest down day or week of the move, accompanied by the heaviest volume.

The stock may have spent weeks climbing steadily, with controlled pullbacks and quick recoveries. Then selling suddenly becomes more aggressive than anything seen during that advance.

That combination can signal institutional distribution. A stock that previously absorbed selling is now struggling under it.

“It’s still well above where I bought it” does not explain away abnormal action.

One bar doesn’t prove the final top is in. But it deserves a reassessment of the position: where the stock closes, whether important support breaks, and how the action compares with its previous pullbacks.

If a sell rule is triggered, I act. I don’t move the standard simply because the stock has made me money or because I still like its story.

A big winner can remain a great company while becoming a poor trade to hold.

You don’t need to prove the top is in to respond to a change in character.

You Don’t Need Hindsight to Spot Stage 3

Someone recently commented that identifying Stage 3 is difficult and questioned whether it can only be spotted after the fact. It’s a fair concern. Recognizing a developing stage 3 takes practice, but it can be done while it is happening.

You won’t necessarily recognize Stage 3 the moment it begins. What initially looks like a normal pullback may gradually reveal a change in character as the evidence builds. That delay does not mean you have to wait until the damage is obvious.

Stan Weinstein and Mark Minervini describe the characteristics of a developing Stage 3. William O’Neil also emphasizes watching distribution, abnormal behavior in leading stocks, and the performance of your recent purchases. These observations help you recognize changing conditions and make decisions while the outcome is still uncertain.

That’s exactly what I walk through in this video. Using chart replay in MTS Velocity, I examine the indexes, sectors, industry groups, and leading stocks to show how the warning signs develop. We discuss what those changes mean for protecting gains, reducing exposure, and deciding when conditions justify getting more involved again.

A potential top can still resolve into another advance, so recognizing Stage 3 requires staying responsive to new evidence. I’ve sped the video up to 1.5× to keep the walkthrough moving. If you’re getting started with stage analysis, this should help you understand what to look for and how to practice recognizing it.

Compounding Isn’t Just About How Long You Hold

Everyone wants the stock that doubles. Fewer people appreciate what a series of smaller winners can do for their account.

When we talk about compounding, we usually talk about time and time is important. Holding an exceptional stock through a sustained advance can produce extraordinary returns.

But Minervini emphasizes another powerful factor: how often you can reinvest your capital and apply your edge.

Consider the simple example in the image:

Starting with $100,000, one 100% gain produces $200,000.

Five consecutive 20% gains, with everything reinvested, produce $248,832.

That’s a 148.83% return without a single trade doubling. If both happen over the same period, the smaller compounded gains finish $48,832 ahead.

This simplified example assumes the entire balance earns each return, with five winners and no losses or trading costs. Actual account results depend on position sizing and the full mix of wins and losses.

But the principle deserves attention: repeated gains can produce an extraordinary result when you reinvest them.

A worthwhile gain captured in a few weeks can free capital for another qualifying opportunity. Each opportunity gives you another chance to apply your edge and compound the proceeds.

The benefit depends on maintaining that edge and controlling losses as you repeat the process.

You don’t need every winner to double for your account to achieve exceptional returns.

You Don’t Need Every Winner to Be a Home Run

A 15% winner can look unimpressive when everyone is talking about stocks that doubled.

But how much did you risk to earn that 15%, and how long did it take?

A 15% gain against a planned 5% risk is a 3R winner.

That’s a meaningful trade. You’ve earned three times your initial planned risk. Across a series of trades, keeping your average gains substantially larger than your average losses, with a sufficient win rate, can support a profitable strategy without requiring a steady supply of 100% winners.

Minervini emphasizes the power of smaller gains compounded over time. When you have an edge, capturing and reinvesting a series of smaller gains can compound capital faster than waiting for one larger move. O’Neil’s familiar 20–25% profit-taking guidelines also recognize the value of capturing intermediate moves, while making exceptions for unusually powerful stocks.

Time matters, too. A gain captured in a few weeks can free capital for another qualifying opportunity. Waiting months for a hoped-for move while better setups develop has an opportunity cost.

Singles and doubles deserve a place in a strategy designed to find exceptional winners.

I screen for stocks with the earnings, sales, relative strength, and price-and-volume characteristics that can support a major advance, but I can’t know in advance which qualifying stock will become the home run.

Some will fail. Some will produce worthwhile gains. A few may develop into something much bigger.

My job is to manage each one as the evidence unfolds: cut losses, take partial profits when justified, protect gains, and give strong positions room to continue.

A 15% gain isn’t an automatic instruction to sell everything. The stock’s behavior, market conditions, and my sell rules guide that decision.

The home runs can emerge from that same process. I don’t have to correctly predict them before buying, and I don’t have to dismiss every smaller winner while waiting for one.

Build a process that makes singles and doubles worthwhile and gives home runs room to develop.

The Best Trades Tend to Prove Themselves Early

When I review my biggest winners, one characteristic keeps showing up: they made meaningful progress soon after the entry. Some accelerated away from the buy point. Others reached 2R or 3R before pulling back and continuing higher.

Jesse Livermore emphasized commitments in a stock or commodity “showing a profit right from the start.”

That’s an important lesson about timing. A good company can spend months going nowhere. A well-timed entry aims to put your capital to work as demand begins moving the stock out of its consolidation.

Early progress gives you a profit cushion and evidence that the setup is working. When that progress never arrives, you need to reassess whether the stock is behaving as expected.

Too many traders make “it hasn’t hit my stop” their entire reason for holding. Days become weeks. The stock chops around, other opportunities develop, and patience gradually turns into an excuse to avoid making a decision.

Normal pullbacks and retests are part of trading. A winner can revisit its entry, and one quiet session doesn’t invalidate a setup. What matters is whether the stock’s behavior remains consistent with your plan and the market environment.

Before entering, know what constructive follow-through should look like. Then evaluate what actually happens: Is the stock advancing, holding its gains, and finding support? Or repeatedly stalling and failing to attract demand?

Your capital has a time cost as well as a price risk.

A trade that hasn’t stopped you out still has to earn its place in your account.

Larry Hite once said in Market Wizards:

“I don’t know of too many people who get rich by taking small profits.”

Everyone knows the famous saying: Cut your losers short and let your winners run. But look at how many traders actually behave. They give a losing position more room because they hope it will recover, then sell a winning position at the first small gain because they’re afraid of giving it back.

They give their weakest trades patience and their strongest trades a deadline.

Hite’s comment came in a discussion about seeing the bigger picture, controlling risk, and following the trend. Catching a meaningful move requires staying with a stock while it continues to act right, including through normal pullbacks and consolidations.

Taking partial profits can help manage risk and make holding the remainder easier, but if you consistently sell your entire position at the first small gain, you never give a potential big winner the chance to become one.

Stop giving your losers the patience your winners deserve.

Great Earnings Don’t Cancel a Stage 3 Top

The company reports great earnings. The headlines are glowing, but the stock has already started acting differently.

Pullbacks are deeper. Price swings are wider. Heavy selling keeps interrupting rallies. Breakouts struggle to hold.

The business can still look strong while the stock is topping.

That’s what makes Stage 3 so deceptive. After a long advance, the story is widely known and the recent results can look outstanding. Fresh buyers see the earnings report and assume the stock has another big move ahead.

That demand can give institutions an opportunity to sell into strength.

A rally on good news might even look like a fresh breakout, but if it reverses on heavy volume and fails to hold the breakout, the headline doesn’t erase that warning.

Watch what the stock does with good news.

Does it advance, hold its gains, and attract support on pullbacks? Or does every attempt higher meet selling?

I care about earnings and sales growth, but I also want the stock’s behavior to confirm those fundamentals. Strong numbers don’t give a deteriorating chart a free pass.

For new buys, a Stage 2 uptrend is my starting requirement. Then I need a qualifying setup, and defined risk.

If a stock repairs its structure and establishes a fresh Stage 2 advance, I can reconsider it. I don’t need to anticipate that recovery because the story sounds convincing.

Great earnings never override evidence of distribution.

EDRY Just Showed Why Sell Rules Matter

EDRY fell 20.44% today on roughly 2.5× relative volume. After a powerful advance that largely followed the 10-day moving average, the stock delivered a clear change in character.

The first warning was the gap below the 10-day. Selling continued through much of the morning, and price then broke through the 20-day. In MTS Velocity, RVOL Now was already flagging elevated volume early in the session, giving us another reason to pay attention.

An alert near your planned exit level brings the stock front and center. Your sell rules determine what you do next. If you caught the earlier breakout, an orderly exit could still leave you with a substantial profit, even after giving back some of the advance.

Unfortunately, catching a big winner doesn’t automatically make someone good at managing it. Without sell rules, it’s easy to keep finding reasons to hold: the earnings still look great, the industry is strong, or the stock will probably bounce. Meanwhile, a meaningful gain starts disappearing.

Kullamägi’s approach is relevant here. His published breakout rules include taking partial profits after the initial burst and trailing the remaining shares with the 10-day or 20-day moving average, using a closing break of the selected average as the exit signal. EDRY finished below both today.

For a swing trader following a similar approach, this is a textbook sell signal. Other traders may have acted earlier under rules for a sharp, heavy-volume breakdown. The important thing is having those rules established before the selling starts.

And if EDRY rebounds tomorrow or reaches new highs again? That wouldn’t invalidate a disciplined exit based on today’s evidence. You evaluate a trading process across many trades, and protecting gains sometimes means leaving before a stock’s final advance.

Sell rules exist because you cannot know which breakdown will recover and which will become a much larger decline.

A single unmanaged position can undo months of good trading. You don’t need to capture the exact top, but you do need to know when your plan says the trade is over.

Give Me the Meat in the Middle

A lot of traders obsess over buying the exact bottom and selling the exact top. I’ve found plenty of success, and a lot more contentment, taking the meat in the middle.

Look at EDRY.

For months, it chopped sideways, developing higher lows and finding support around the 50-day. Buying a pullback might have kept you involved, but your capital could have spent considerable time waiting for sustained progress. Minervini addresses this directly: money sitting in a stock that goes nowhere has an opportunity cost while other setups develop.

Then August brought an explosive earnings move on heavy volume.

Buying immediately before the announcement would have meant gambling on the market’s reaction. Instead, you could wait and study that reaction, how well the stock held its gains, and whether buying continued afterward. Missing the first burst doesn’t necessarily mean missing the opportunity.

EDRY then tightened up. After several sessions of strong momentum, price moved sideways and volume dried up. Both Minervini and O’Neil describe tight price action accompanied by contracting volume as constructive evidence that selling pressure is diminishing.

When volume returned and price pushed out of that short consolidation, there was an entry opportunity with a nearby low against which to define risk. Depending on the entry, the low of the day could also serve as the stop.

As O’Neil writes: “You want a stock to prove its strength to you before you invest in it.”

From there, EDRY largely followed its 10-day moving average higher. Now the sharp break beneath that line on heavy volume, toward the 20-day, marks a change in behavior. For a swing trader managing this move around those averages, that deserves attention.

Kullamägi’s published approach includes taking partial profits and trailing the remaining position with the 10-day or 20-day moving average. His moving-average exit rule looks for a close below the selected line, which matters when evaluating an intraday break.

There were opportunities to sell some into strength along the way, too. Many successful traders have made the broader point that consistently capturing the exact low and high is unrealistic. Successful trading leaves some of the move behind.

You could miss the bottom, wait until after earnings, and exit below the peak while still capturing a substantial move.

That’s why I maintain a watchlist, set alerts, and look for momentum followed by tightness, drying volume, and renewed demand.

Give me a sound entry and defined risk. The meat in the middle is enough.

And if I miss it? Stay patient and move on to the next setup.

One Exception Can Undo Months of Discipline

You can follow your rules for 20 trades, then give back much of that progress on the one you refuse to sell.

Maybe it was your biggest winner. Maybe you love the company. Maybe you’ve become convinced that its entire industry has an incredible future.

Then the price action changes. Sell signals appear. And you start explaining them away.

“This one deserves more room.”

“The market doesn’t understand it.”

“I’ll sell when it comes back.”

The danger is giving your favorite stock permission to break rules you would enforce on everything else.

Some stocks will continue higher after I sell. That alone doesn’t make the exit a mistake. I can accept leaving money on the table when I’ve followed a sound sell plan.

But ignoring my stop or abandoning my profit-protection rules because I’m attached to a stock can turn a successful stretch into a damaging drawdown.

Before I enter, I need a plan for handling both a losing trade and a profitable one. Then I have to follow it when the decision becomes uncomfortable.

A stock doesn’t earn an exemption from my rules because it made me money in the past.

The Story Can Still Sound Great After the Stock Has Topped.

“The earnings are still growing.”

“The company is an industry leader.”

“The long-term opportunity is enormous.”

All of that can be true while the stock is breaking down.

Stocks trade on expectations for the future. They can peak while reported earnings and sales still look excellent, then decline as investors anticipate slower growth ahead.

That’s why I don’t wait for the business story to fall apart before selling.

Earnings and sales help me find potential leaders, but once I own a stock, strong fundamentals don’t give it permission to violate my sell rules.

Normal pullbacks are part of an uptrend. I’m watching whether the stock continues to act constructively or whether signs of abnormal price and volume action are piling up.

If my sell rules are triggered, I act. I don’t need the next earnings report to justify the decision.

By the time the fundamental weakness becomes obvious, the stock may already have surrendered a large part of its advance.

Don’t let a good story talk you out of a disciplined exit.

3 Trading Rules I Wish I’d Taken Seriously Sooner.

Some of the biggest improvements in my trading came from ideas I already knew, but wasn’t consistently putting into practice.

1. Cutting losses short and letting winners run. Actually doing it.

Everyone knows the mantra. Following it means accepting when you’re wrong, taking the loss, and giving your winners a chance to become meaningful.

Knowing the rule doesn’t protect your account. Following it does.

2. Position sizing.

Arguably the most important of the three, and often one of the last things traders learn.

Your position size and the distance to your stop determine how much you’re planning to risk. A good setup can still be a bad trade for your account if you size it too large.

3. Progressive exposure.

When my trades are working, I build on that success: more qualifying setups, larger positions, and gradually more account exposure.

When things stop working, I reverse that process. Smaller positions. Fewer new trades. Less exposure.

Sometimes I pause new buys and manage the positions that are still working. Sometimes I move to cash.

My results help determine how aggressive I get. The standards for taking a trade stay the same.

The personal bonus: protecting break-even helps me hold winners.

This is something I picked up from Mark Minervini, and it fits my personality.

Once a trade has made meaningful progress, I may sell some into strength and raise my stop to break-even. Or I may keep the original stop and take enough profit to cover the planned risk on the remaining shares.

The aim is to protect the overall trade around break-even or better at my planned exit, while leaving room for a larger move.

Taking partial profits can reduce my eventual gain. I accept that trade-off because reducing the original downside helps me stay patient with the remaining position.

It also helps me stay willing to take the next qualifying setup when my results justify adding exposure.

I screen for characteristics shared by some of the biggest winners in history. That gives me a process for choosing candidates. It still doesn’t tell me which one will become the big winner.

Some will fail. Some will go nowhere. Others may run much further than I expected.

That’s why Minervini’s approach resonates with me: taking some profit to help finance the remaining risk makes it easier for me to give a winner time.

Know yourself well enough to build a process you can actually follow.

Larry Hite put it perfectly in Market Wizards:

“If you don’t bet, you can’t win. … If you lose all your chips, you can’t bet.”

“I’ll Sell When It Comes Back.”

In How to Make Money in Stocks, William O’Neil shares a story from Fred C. Kelly that every trader should remember.

A man sets a turkey trap. Twelve turkeys walk inside, and all he has to do is pull the string.

But one walks out.

He decides to wait for it to return. Then two more leave. Now he wishes he had settled for eleven, but tells himself he’ll pull the string if just one comes back.

He keeps bargaining until every turkey is gone.

How often do we do the same thing with a stock?

You had a healthy profit. The stock starts breaking down, but you’re anchored to what the position was worth. You tell yourself, “If it just gets back to where it was yesterday, I’ll sell.”

Then yesterday’s price gets farther away, and you lower the price you’re willing to accept. The selling rule you had before entering the trade gets replaced by a negotiation with yourself.

The market has no obligation to return to the price you wish you had sold at.

Give a stock room according to your strategy. When your selling rules trigger, follow them. Hoping to recover a previous gain or avoid admitting a loss is not a reason to keep holding.

As O’Neil put it:

“To reduce your stock market risk, stop counting turkeys.”

The Gap That Looks “Too High” May Be the Start.

A stock gaps higher, and your first thought is, “I missed it.”

Not so fast.

I want to know what happened before the gap, and what’s driving it.

Is it emerging from a base on huge volume after a strong earnings and sales report? Is there a major industry shift, like the demand for memory supporting the AI buildout? Is the company delivering a meaningful turnaround?

Did something significant catch the market off guard, with the growth fundamentals to support a sustained advance?

I’m looking for something new that changes the outlook. That’s a central part of the N in CAN SLIM.

With that context, a powerful gap can be an extremely bullish signal. The market may be reacting to a change it hadn’t fully priced in.

That doesn’t mean I have to buy immediately.

Maybe the stock runs for a few days, then forms a tight consolidation. Or it pulls back gently on light volume, holds most of its gap, and starts moving higher again. Some traders enter as strength returns after the pullback; others wait for a breakout to new highs.

There are different ways to enter. The gap gets my attention, but I still want a proper setup to act on.

Now consider a stock that has already been a leader for months. Its advance accelerates, it becomes stretched far above its base, and then it gaps sharply higher on enormous volume.

That can be an exhaustion warning, potentially part of a climax top. Even outstanding earnings don’t erase that possibility.

Just as I consider the overall market environment, I have to consider the individual stock’s history, fundamentals, and position within its trend.

A huge gap can signal a fresh opportunity or warn that a move is nearing exhaustion. The context gives it meaning.

The Earnings Look Great. The Stock Disagrees.

Imagine a company reports earnings up 50% and sales up 30%. You love the numbers. Then the stock gaps down on heavy volume and breaks support.

Your first thought: “That makes no sense. The report was great.”

Martin Zweig addressed this in Winning on Wall Street:

“The worst thing the stock can do on news of earnings is to drop sharply.”

Zweig looked for earnings and sales growth, just like O’Neil, but he also examined how the stock reacted. A sharp decline could eliminate a stock from consideration, even when the report looked good to him.

The trap is becoming so attached to the numbers that we use them to justify holding, adding, or giving a deteriorating stock “a little more room.”

We use strong earnings and sales growth as screening criteria because those characteristics have appeared in many of the market’s biggest winning stocks, including many of our own winners.

But those fundamentals never trump price action.

The market is full of emotional human beings acting on different expectations, fears, and information. The market is also forward looking and its behavior doesn’t have to make sense to you. Believing a stock should be going higher won’t stop it from going lower.

That’s what I mean when I say the market is always right. Whatever our analysis says, the price determines what happens to our money.

We don’t have to agree with the price action. We do have to respect it.

The Same Stock Move Can Be a Reason to Hold or Sell

A stock surges on heavy volume. Is that a reason to take profits or hold for a much bigger move? The answer depends on what happened before the surge.

Rules matter, but so does the context in which you apply them. Even fully systematic traders have to account for market conditions: a system with positive expectancy across thousands of trades in one environment can struggle when that environment changes.

Consider a stock with strong earnings and sales growth emerging from a long base. A rapid advance on heavy volume can be evidence of powerful demand and the beginning of a major winner. Automatically selling the entire position because it went up “too much, too fast” can cut short the very opportunity you spent months looking for.

Now consider that same acceleration after a stock has already advanced for more than a year and formed several successive bases. That burst of buying could be a climactic move near the end of the run. O’Neil’s examples of climax tops illustrate why the stock’s prior advance matters.

Similar price action. Different stages of the move. Different implications.

That doesn’t mean abandoning stops or refusing to take partial profits. It means recognizing when the evidence supports giving a potential leader more room to develop and when it supports protecting gains more aggressively. Neither outcome is guaranteed, but the difference matters.

Everyone wants a rule that tells them exactly what to do. Developing judgment means learning to recognize the situation that rule was designed for.

Before asking, “Should I sell this strength?” ask, “Where is this strength occurring within the stock’s larger move?”
