Is IBM’s Quantum Advantage Enough to Justify Its 31% 2025 Stock Surge?

If you’re wondering whether now is the time to buy, hold, or rethink International Business Machines, you’re not alone. IBM has made plenty of headlines lately, not just from Wall Street analysts, but from major outlets reporting on its promising momentum in quantum computing and its leadership moves in artificial intelligence. And if you’re tracking performance, the numbers might have caught your eye: IBM’s stock is up 31.0% year-to-date and has notched a 165.7% gain over the last three years. These are not the kind of moves you’d expect from a “dinosaur” of tech.

Much of this growth comes from a renewed sense of excitement and, frankly, a bit of changing risk perception among investors. Reports highlighting IBM’s favorable position in the “Quantum advantage” race, with companies like Google and Microsoft in the mix, have given Big Blue some futuristic sparkle. Shorter-term moves aren’t being left behind either. In the past month, IBM’s stock has soared 11.2%, and even in the last seven days, there’s been a modest 0.5% uptick. It’s not just a bounce; the growth is part of a wider story, where old tech is finding new relevance and investors are taking note.

But what about valuation? On that front, the “scoreboard” says IBM is undervalued in just 1 out of 6 standard checks. That presents an intriguing puzzle. Should you trust the numbers, or are there other factors at play raising IBM’s ceiling? Let’s look at how these traditional valuation methods stack up, and stick around, because by the end, we’ll explore what could be a much smarter way to judge a company’s worth.

International Business Machines scores just 1/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.

Approach 1: International Business Machines Discounted Cash Flow (DCF) Analysis

The Discounted Cash Flow (DCF) method is a popular approach that estimates a company's true value by projecting its future cash flows and discounting them back to today's dollars. In essence, it’s a way of asking: how much are all IBM’s expected future profits worth right now?

For International Business Machines, analysts report current Free Cash Flow at $11.5 Billion. Estimates from multiple analysts suggest cash flows will steadily grow over the next five years, reaching about $18.7 Billion by 2029. Beyond that, projections are extrapolated using modest assumptions to envision FCF crossing $24.1 Billion by 2035. Readers should note that accuracy tends to decrease the further out we go.

Putting these numbers together using the DCF model, the estimate for IBM’s intrinsic value comes to $290.21 per share. Right now, IBM’s share price is trading just 0.7% below this level, which means the market price is very close to what the model suggests the company is worth.

Approach 2: International Business Machines Price vs Earnings

The Price-to-Earnings (PE) ratio is a tried-and-true metric that offers a quick snapshot of how investors are valuing a profitable company like International Business Machines. The PE ratio is especially useful for companies with steady earnings, as it connects what you pay as an investor to the company’s bottom-line profits. Fast-growing firms with lower risks and wider profit margins often carry higher PE ratios, while businesses with uncertain outlooks or shrinking earnings tend to trade at lower multiples.

IBM currently trades at a PE ratio of 45.8x, which stands notably above both the average for its IT industry peers at 32.4x and the peer group average at 21.0x. These benchmarks offer context but may not factor in IBM’s unique growth profile, market positioning, or any potential risks attached to its business.

That is where Simply Wall St’s proprietary "Fair Ratio" comes in. The Fair Ratio, calculated as 43.4x for IBM, takes a deeper dive by weighing elements like the company’s projected earnings growth, risk profile, industry, profit margins, and size. This tailored approach is a more nuanced gauge of fair value compared to simply looking at averages, since it aims to capture what makes IBM truly different from its broader peer set.

Comparing IBM’s actual PE ratio (45.8x) with its Fair Ratio (43.4x), the numbers are quite close, with less than a 0.10 difference. This suggests that, at current levels, the stock price aligns well with fundamental expectations.

Upgrade Your Decision Making: Choose your International Business Machines Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let's introduce you to Narratives. A Narrative is simply your story, the unique perspective you have about a company, linked directly to your assumptions behind the numbers: what you believe are reasonable future revenues, earnings, profit margins and fair value. Narratives connect the dots from a company's story to a financial forecast and finally to a fair value, putting you in the driver’s seat on why a stock is fairly priced, overvalued, or a bargain in your eyes.

Narratives are easy to use and available to everyone on Simply Wall St's Community page, used by millions of investors. They make it possible to compare the fair value you assign to International Business Machines with the current share price. This can help you decide if it is time to buy, sell, or hold, based on your outlook. Even better, Narratives update automatically when new earnings or breaking news is released, so your view of IBM is always fresh and fact-based.

For example, some investors see IBM as a transformative leader with a fair value of $350 based on robust AI and cloud growth, while others anticipate competitive headwinds and assign a fair value as low as $198. Narratives let you confidently invest according to your own logic and beliefs, rather than guesswork or hype.

For International Business Machines, we'll make it really easy for you with previews of two leading International Business Machines Narratives:

🐂 International Business Machines Bull Case

Bull Case Fair Value: $350.00

Current price is 17.7% below Bull Case fair value

Expected Revenue Growth Rate: 6.1%

  • IBM is positioned for sustained growth and premium valuation due to accelerated AI, hybrid cloud, and digital modernization adoption in regulated sectors, which may drive profitability.
  • Integration of key acquisitions and innovation in quantum computing could boost high-margin software, increasing predictable free cash flow.
  • Main risks include declining legacy revenues, competition, open-source disruption, talent shortages, and elevated debt levels.

🐻 International Business Machines Bear Case

Bear Case Fair Value (Consensus): $281.32

Current price is 2.4% above Bear Case fair value

Expected Revenue Growth Rate: 5.1%

  • IBM’s hybrid cloud, AI, and strategic acquisitions drive client modernization, but macro uncertainty and competition threaten revenue and margin growth.
  • Investments in z17 mainframe and generative AI may boost earnings, but volatility in consulting and software segments could dampen prospects.
  • Risks include currency fluctuations, competitive pressures, and reliance on discretionary spending and consumption-based services.
