Celestica Inc. (CLS): Among the Worst Performing AI Stocks of Previous Week

We recently compiled a list of the 20 Worst Performing AI Stocks of Last Week. In this article, we are going to take a look at where Celestica Inc. (NYSE:CLS) stands against the other AI stocks.

US Stocks in September

This September saw a sluggish start for most US stocks, and large-cap technology stocks were no exception to this trend. The main driving factors for this development include concerns over the health of the American economy resurfacing, particularly in light of the August jobs report. The report underscored the labor market’s weakness in the US, which has not left investors feeling all that secure about the state of the economy.

On the stock side, many investor favorites in the artificial intelligence (AI) space have been doing poorly so far in September, with losses ranging from around 4% to even over 20% for the first week of September. The primary reason for this decline seems to be that investors are just not satisfied with the growth demonstrated by major AI companies at present. While growth is definitely present, it’s continuing to fall short of investor expectations, which have increased exponentially in light of the hype cycle created around AI stocks.

Are We Really In An AI Bubble?

The first week of September was actually the worst week for chip stocks recorded in over two years. Many investors are now beginning to wonder whether AI is worth the amount of money being poured into it, resulting in corporate spending on AI coming under greater scrutiny than ever before. The greater scrutiny is predominantly because of investors and analysts now thinking that many AI stocks are overhyped and overvalued and don’t have the means to justify this hype and valuation – essentially, the main concern is that we’re in an AI bubble that’s on the brink of bursting.

However, as with any high-tension market situation, there are diverging opinions as well. In his September 6 interview on CNBC’s “Closing Bell Overtime,” Deepwater Asset Management’s managing partner, Gene Munster, emphatically stated that we are not in an AI bubble. For him, the bigger problem in the AI space is that every other company today is trying to talk about AI and say that it’s working towards AI incorporation in its operations – something that’s leading to a lot of noise in the market, which is drowning out the voices of companies offering real substance in this space. He thus noted that it’s important for investors to be careful not to invest in just any company that says it’s working with AI and instead to focus on the better, perhaps more boring, options in the market.

According to Munster, the main players to keep your money in are predominantly big tech names, as these are the only companies that are poised to deliver substantial growth instead of just generating noise. However, investors are still confused about whether AI is a good place to invest in even today, which is why we’ve compiled a list of the worst performing AI stocks in September so far and explained whether these stocks are worth picking up or if they’re just temporary beneficiaries of the hype around AI.

Our Methodology 

We compiled our list by screening for AI stocks that have seen declines of 10% or above in the first week of September, and then ranked the stocks based on their weekly decline as of Friday, September 6. We have also mentioned the number of hedge funds holding stakes in each stock.

Why are we interested in the stocks that hedge funds pile into? The reason is simple: our research has shown that we can outperform the market by imitating the top stock picks of the best hedge funds. Our quarterly newsletter’s strategy selects 14 small-cap and large-cap stocks every quarter and has returned 275% since May 2014, beating its benchmark by 150 percentage points.

Celestica Inc. (NYSE:CLS)

Weekly Decline: 19.71%

Number of Hedge Fund Holders: 38

Celestica Inc. (NYSE:CLS) is an information technology company based in Toronto, Canada. It provides supply chain solutions to tech firms and has been benefitting immensely from the growing demand for AI-related hardware. The company is a leading provider of connectivity products for data centers and is renowned for its 400G and 800G switches.

Like other AI stocks, Celestica Inc. (NYSE:CLS) has seen a shocking decline in the first week of September. As a result, the stock has gotten caught up in a global sell-off of highly appreciated AI stocks, which is making many investors still sticking with Celestica Inc. (NYSE:CLS) consider exiting their positions.

Additionally, recent fears surrounding the American economy have also instilled concern among Celestica Inc. (NYSE:CLS) shareholders. Since this company’s business is highly cyclical and volatile, considering the fact that its growth is dependent on customer demand, many investors are worried about falling customer demand forecasts and what this may mean for Celestica Inc. (NYSE:CLS). The only position that might work with this stock is if you buy and hold on to it long-term since only then would you be able to generate a meaningful return on your investment. Otherwise, Celestica Inc. (NYSE:CLS) is not looking too attractive for short-term investors.

We saw 38 hedge funds long Celestica Inc. (NYSE:CLS) in the second quarter, with a total stake value of $843.9 million.

Overall CLS ranks 2nd on our list of the worst performing AI stocks last week. While we acknowledge the potential of CLS as an investment, we believe that AI stocks hold promise for delivering high returns and doing so within a shorter timeframe. If you are looking for an AI stock that is more promising than CLS but that trades at less than 5 times its earnings, check out our report about the cheapest AI stock.

Undervalued AI Stock Poised for Massive Gains: 10,000% Upside

AI game is changing.

The chip guys, like Nvidia, they had their moment. The first AI wave? They rode it high.

But guess what? That ride’s over. Nvidia’s been flatlining since October 2025.

Remember the internet boom? Everyone thought Cisco and Intel were the kings, right? Wrong. The real money was made by the companies that actually used the internet to build something new: e-commerce, search engines, social media.

And it’s the same deal with AI. NVDA? They’re yesterday’s news. The real winners? They’re the robotics companies, the ones building the robots we only dreamed about before.

We’re talking AI 2.0. The first wave was about the chips, this one’s about the robots. Robots that can do your chores, robots that can work in factories, robots that will change everything. Labor shortages? Gone. Industries revolutionized? You bet.

This isn’t some far-off fantasy, it’s happening right now. And there’s one company, a robotics company, that’s leading the charge. They’ve got the cutting-edge tech, they’re ahead of the curve, and they’re dirt cheap right now. We’re talking potential 100x returns in the next few years. You snooze, you lose.

My name is Inan Dogan. I’m the co-founder and Research Director of Insider Monkey. I have an important message for you today.

Since March 2017, my stock picks have returned 16.5% annually. Today, I’ve found an opportunity even bigger than my British American Tobacco call.

Two years ago, Wall Street wrote off British American Tobacco (BTI) as a “melting ice cube.” The stock had crashed 40% from its peak, and consensus said the business was dying.

We looked under the cover and realized they were wrong.

We alerted our subscribers, and BTI returned 90% in just 16 months.

Now if you had invested just $10,000 in BTI in June 2024, you’d be sitting on $19,000 in October 2025.

Today, we have identified a nearly identical pattern in a digital-first giant trading at $3.

While the market panics over a surface-level revenue decline, our PhD-led research shows management has actually surgically cut $100 million in waste to focus on high-margin growth.

This pattern is a hallmark of our 16.5% annual return track record. The current opportunity offers a 400% upside potential—dwarfing even our 90% BTI return.

Get the ticker for our new “Underdog” pick and the full BTI case study for just 99 cents.
