This year, 2025, has started off positively for the stock market. S&P 500 index has risen by 16% so far. While that’s not a life-altering gain, some individual stocks have really outshined the rest. A lot of these companies are tapping into the buzz around generative artificial intelligence (AI) and quantum computing hype, although it feels like investor enthusiasm might be outpacing the actual numbers.
So, let’s talk about why these companies draw investors in, specifically Palantir Technologies (NASDAQ:PLTR) and Quantum Computing Co., Ltd. (NASDAQ:QUBT). It could be wise to think about cashing out some profits here.
Palantir’s stock has skyrocketed by 153% this year, marking it as a lucrative choice for those holding it long-term. And, I mean, it’s clear why: data analytics firms are increasingly in demand. Large language models are utilized to enhance services for businesses and government clients. Plus, its established connections and history give it quite the edge in the challenging world of defense and law enforcement contracts. But hey, just because a business is strong doesn’t mean it’s a great investment.
This year has really propelled Palantir forward, reaching a market cap of $461 billion. That’s quite impressive; it’s actually larger than most publicly traded companies in Europe or Japan, ranking as the 19th largest in the U.S.
However, Palantir isn’t necessarily more profitable than others in its field; it’s just valued highly. The stock’s forward price-earnings ratio (P/E) stands at an eye-popping 262 times. In comparison, companies like Nvidia, Taiwan Semiconductor Manufacturing, and Microsoft look relatively inexpensive.
On a brighter note, Palantir is witnessing considerable growth, with third-quarter revenue soaring by 63% year-over-year to $1.2 billion. Still, there’s a catch—if investors have already factored in such high expectations, even solid results might not be enough to move the market.
Now, Quantum Computing Inc. (QCi) has seen a sharp decline since early October, wiping out most of 2025’s earlier gains—down around 40% this year. Yet, the stock is still deemed quite pricey, having surged over 600% in the past year. As its name suggests, they are trailblazers in the quantum computing hardware sector, but the current prices are more influenced by excitement than by actual sales or profits.
Analysts at McKinsey & Company speculate that we might not see a commercially viable quantum computer operating at scale until 2040. Alphabet, being a key player in this field, claims they could have products on the market within five years. But even if they get the tech right, it might take a long time to build a sustainable business around it.
Generative AI serves as a cautionary tale here. For instance, OpenAI reportedly lost about $12 billion in Q3, despite having a service that many consider technologically sound. So, it’s probably unwise to anticipate that quantum computing will achieve commercial success anytime soon, especially given the substantial tech obstacles ahead.
With profit-making still far down the road, investors need to assess QCi’s financial situation carefully. In the second quarter, its revenue plummeted by 66% to just $61,000, a small figure for a company valued at $2.5 billion. Meanwhile, losses almost doubled to $10.2 million. Those considering buying QCi stock now may also face the reality of significant dilution of their shares since the company might rely on selling more stock to fund its ongoing cash-burning efforts.
Both Palantir and Quantum Computing seem to carry considerable risks, so if you own their stocks, it might be worth cashing in some gains. Conversely, if you’re considering entering, be cautious. The short positions are certainly a thing to think about. As an old economist famously said, markets can stay irrational longer than one can remain solvent. And these stocks are definitely susceptible to hype, which can boost prices even if the underlying fundamentals aren’t as strong as they appear.
Before jumping into an investment in Palantir Technologies, it might be a good idea to consider a few points.
Overall, be cautious and remember that the stock market is unpredictable.
