Have you ever held a stock that just kept climbing, week after week, until it felt almost too good to be true? That rush of watching your position double in value can be intoxicating. But then comes that nagging voice in the back of your mind: is this sustainable, or am I riding a rocket that’s about to run out of fuel? Recently, one well-known investment approach faced exactly that dilemma with a stock that’s been on fire this year. The decision? To take some chips off the table. And honestly, it’s a move worth dissecting because it highlights one of the hardest parts of investing—knowing when to sell.
Markets have a way of testing our resolve. When everything is going up, conviction feels unbreakable. Yet the smartest players often remind us that discipline trumps conviction every single time. That’s precisely what played out here. After an incredible run fueled by massive demand in the tech infrastructure space, the choice was made to reduce exposure slightly. Not abandon ship—just trim the sails a bit. Let’s dive into why this happened, what it means, and whether it signals caution or opportunity.
The Parabolic Rise That Caught Everyone’s Attention
Picture this: a company that’s been around for decades, known more for steady innovation than explosive growth, suddenly becomes one of the hottest names in the market. That’s exactly what happened in 2026. The stock surged more than 50% year-to-date, landing it among the top performers across major indices. We’re talking about a move so sharp it qualifies as parabolic—that steep, almost vertical climb that makes headlines and gets everyone talking.
What sparked this? Simple: the insatiable hunger for next-generation infrastructure to power artificial intelligence. Data centers are expanding at breakneck speed, and the backbone of all that connectivity relies heavily on advanced optical fiber and cabling. One major tech giant signed a blockbuster multiyear supply deal worth billions, locking in demand and sending shares soaring. It wasn’t just one contract; the broader trend of hyperscalers racing to secure supplies created a perfect storm of momentum.
I’ve watched similar setups unfold before. When a company pivots into a high-growth area like AI-related hardware, the initial reaction is often euphoric. Valuations stretch, multiples expand, and the narrative becomes almost irresistible. But euphoria can blind us to risks. That’s why trimming makes sense—not because the story is broken, but because the price has gotten ahead of itself.
Why Discipline Matters More Than Ever
Let’s be real: holding onto winners feels great. Selling them? Not so much. Yet the best long-term results come from those willing to act against emotion. In this case, the portfolio reduced its position by about 50 shares at around $133 each. That dropped the weighting from roughly 2.2% to 2%. Small move on paper, but symbolically huge.
This wasn’t knee-jerk selling. It followed internal debate—conviction in the company’s future versus the need to respect rules against chasing parabolic moves. The rule won out. Why? Because history shows that stocks that go vertical often correct sharply. Taking profits locks in real gains (here, about 55% since entry last fall) and provides dry powder for better opportunities later.
Discipline trumps conviction every time. You can love the story, but markets don’t care about feelings.
– A seasoned investor’s mantra
That quote resonates deeply. I’ve seen too many investors ride winners all the way back down because they couldn’t bear to sell. A modest trim strikes a balance: you stay invested in the upside while protecting against downside surprises.
Breaking Down the Core Investment Thesis
At its heart, the bullish case remains solid. Optical communications are critical for modern data centers. Traditional copper connections can’t handle the bandwidth and density required for AI workloads. Fiber optics solve that problem, enabling faster, more efficient data transfer over longer distances with less power loss.
- AI models demand massive compute power, which means more servers packed closer together.
- That density requires high-performance cabling to avoid bottlenecks.
- Hyperscalers are spending trillions on infrastructure—securing supply chains is a top priority.
- Recent multibillion-dollar agreements signal strong visibility into future revenue.
These factors aren’t going away. If anything, demand should accelerate as more companies build out AI capabilities. So why trim? Because even great stories can have pauses. Valuations matter. When a stock becomes the sixth-best performer in a major index in just two months, it’s fair to ask if expectations have gotten overheated.
In my experience, the most dangerous time isn’t when things look bad—it’s when they look perfect. That’s when discipline becomes your best friend.
What the Trim Actually Means for Positioning
After the sale, the holding remains meaningful but no longer oversized. Reducing from 2.2% to 2% might seem minor, but in a diversified portfolio, every percentage point counts. It frees up capital without abandoning the position entirely. If shares pull back—as parabolic movers often do—there’s room to add again at better prices.
The rating was adjusted accordingly. No longer an aggressive buy; more of a “hold and wait for opportunity.” That shift reflects realism. The long-term outlook is positive, but near-term froth warrants caution. It’s not bearish—just prudent.
| Metric | Before Trim | After Trim |
| Shares Owned | 650 | 600 |
| Portfolio Weight | ~2.2% | ~2% |
| Realized Gain | N/A | ~55% |
| Rating | Higher Conviction | Wait for Pullback |
This table illustrates the measured approach. Nothing dramatic, but strategically sound.
Broader Lessons for Today’s Market
2026 has been wild so far. AI enthusiasm has lifted many boats, but not all rises are created equal. Some stocks benefit from real secular tailwinds; others ride hype. Distinguishing between them requires looking beyond headlines.
Here, the tailwind is genuine. Data center spending isn’t slowing anytime soon. But parabolic moves invite volatility. One disappointing update, one shift in sentiment, and corrections can be swift. Trimming into strength prepares you for that.
Perhaps the most interesting aspect is how this reflects maturity in investing. Early in a career, we chase every winner. Later, we learn to harvest gains systematically. It’s not sexy, but it’s effective.
- Identify strong secular trends (like AI infrastructure).
- Enter positions when valuations are reasonable.
- Monitor momentum carefully.
- Trim into strength to manage risk.
- Re-enter on weakness if fundamentals hold.
Simple framework, yet powerful. It keeps emotion in check and portfolios balanced.
Looking Ahead: Potential Scenarios
What happens next? Several paths are possible. If more supply deals emerge, the rally could extend. Additional announcements would reinforce the narrative and potentially push shares higher. On the flip side, if market sentiment cools or competition intensifies, a pullback becomes likely. Either way, having taken some profits positions investors well.
From a valuation standpoint, the stock trades at elevated multiples compared to historical norms. That’s not necessarily bad in a growth phase, but it does raise the bar for execution. Any stumble could trigger a re-rating.
Personally, I think the company is well-positioned for the long haul. Manufacturing expansions, innovation in next-gen products, and sticky customer relationships all point to durability. But near-term? A breather wouldn’t surprise me. And that’s okay—breathers create buying opportunities.
Investing isn’t about being right every day. It’s about being right over time while managing risk intelligently. Trimming a winner isn’t admitting defeat; it’s playing smart defense. In a market full of noise, that quiet discipline often separates consistent performers from flash-in-the-pan successes.
So next time you see a stock go parabolic, ask yourself: am I riding conviction, or respecting discipline? The answer might just save you from the next painful correction. And who knows—maybe it’ll let you buy back in cheaper down the road.
