MSFT vs SKM: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: SKM is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. MSFT and SKM share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined MSFT and SKM exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Microsoft (MSFT) is one of the largest and most diversified technology companies in the world, operating across three reporting segments. Productivity and Business Processes includes Microsoft 365 (Office, Teams, Dynamics 365) and LinkedIn. Intelligent Cloud covers Azure, GitHub, server products, and enterprise services. More Personal Computing spans Windows, gaming (Xbox plus the acquired Activision Blizzard), Surface devices, and search via Bing. Azure is the second-largest cloud computing platform in the world behind AWS, and Microsoft 365 is the dominant productivity suite for businesses globally. AI is woven across all of it through the Copilot product line and a deep partnership with OpenAI, in which Microsoft is both the primary cloud provider and a major investor. The company was founded in 1975 by Bill Gates and Paul Allen, is headquartered in Redmond, Washington, and is led by CEO Satya Nadella (since 2014). Microsoft is consistently the largest or one of the two largest publicly traded US companies by market cap, with enormous recurring cash flow and a multi-decade dividend-growth streak.

SK Telecom is Korea's largest wireless carrier, with 23.5 million mobile subscribers at the end of 2025 and a 41.6% share of a three-operator market, ahead of KT at 30.8% and LG Uplus at 27.6%. Revenue splits into three reportable segments. Cellular services, covering wireless service fees, interconnection and handset sales, produced KRW 12,552.5 billion of 2025 revenue. Fixed-line runs through SK Broadband, now 99.1% owned with the residual 0.9% under agreement, which sells broadband to 7.2 million homes, IPTV to 6.7 million and telephone service including VoIP to 3.3 million, and booked KRW 4,540.6 billion. Everything else, including commerce, the enterprise business and the young AI data centre operation, sits in a third bucket. Group revenue was KRW 17.10 trillion in 2025, near US$11 billion to US$12 billion depending on the exchange rate applied. SK Inc. owns 30.6% of the shares. SK Square, the semiconductor and ICT investment company that holds the group's SK hynix stake, was split out of SK Telecom in November 2021 and distributed to shareholders, so it is a sibling listing rather than a subsidiary. In September 2025 management folded its scattered AI units into one internal organisation it calls the AI Company-in-Company.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• MSFT drivers: AI as the platform; Closing the gap with AWS in cloud.
• SKM drivers: The AI data centre programme is the entire growth case; Cellular is shrinking, and the 2026 profit rebound is largely a base effect.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The largest open question is the return on AI capex: Microsoft is spending more than $50 billion a year on AI and cloud infrastructure, and if enterprise adoption is slower than expected the payback stretches out. For SKM, the 2025 cybersecurity incident is not closed.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick MSFT if you believe its drivers more; SKM if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the MSFT and SKM guides.

MSFT. For comparison, the S&P 500 trades at roughly 22x earnings on average. Microsoft's premium reflects its combination of growth, durability, margins, and AI exposure through Azure and OpenAI. It is not the highest P/E in mega-cap tech; NVIDIA, for example, trades at roughly 50x. The premium is justified as long as Azure keeps growing double digits and the AI capex earns a return; multiple compression risk rises if cloud growth slows. All figures are approximate as of early 2026 and refresh quarterly; verify against Microsoft's investor relations page or your broker.

SKM. Trailing earnings are depressed by the 2025 breach costs, which is why a trailing P/E near 33 sits so far above a forward figure near 16. On EV/EBITDA around 7.6 the operating business screens close to other incumbent Asian carriers, so most of the ADS re-rating has arrived through the AI data centre story rather than through telephone economics. Book value and the dividend anchor the other side of the case, and neither has moved much since 2023.

Headline figures (approximate, early 2026): MSFT shows revenue (fy2025 ending june) ~$245 billion, growing ~15% year over year, operating margin ~45%, among the highest of any company at Microsoft's scale, net income ~$95 billion, eps (ttm) ~$12.80; SKM shows revenue (ttm) ~KRW 17.06 trillion for the twelve months to June 30, 2026, roughly US$11 billion to US$12 billion depending on the won rate applied, against KRW 17.10 trillion in fiscal 2025, KRW 17.94 trillion in 2024 and KRW 17.64 trillion in 2023. SK Telecom reports in Korean won under IFRS, so a screener line reading 17,058,105 is KRW millions and not US dollars. Second-quarter 2026 revenue was KRW 4,359.1 billion, up 0.47% year over year, while first-half revenue of KRW 8,751.4 billion was down 0.47%., earnings and margins Operating income was KRW 1,048.5 billion in 2025 under IFRS, down from KRW 1,690.9 billion in 2024 and KRW 1,756.3 billion in 2023, with the fall driven by the KRW 134.8 billion regulatory fine and KRW 212.0 billion of cybersecurity response costs. The recovery shows in 2026: second-quarter operating income of KRW 566.0 billion was up 67.3%, and profit for the quarter of KRW 466.0 billion was up 459.8% against that weak base. Trailing twelve-month earnings run about KRW 3,432 per common share, near KRW 1,907 per ADS at the five-ninths ratio., segments and operating metrics Cellular services produced KRW 12,552.5 billion of 2025 revenue and KRW 744.2 billion of segment operating profit, down 52.7%. SK Broadband contributed KRW 4,540.6 billion of revenue and KRW 141.5 billion of profit. AI data centre revenue was KRW 136.2 billion in the second quarter of 2026, up about 92%. SK Telecom ended 2025 with 23.5 million mobile subscribers and 41.6% share, against KT at 30.8% and LG Uplus at 27.6%, plus 7.2 million broadband and 6.7 million IPTV subscribers. Monthly ARPU excluding MVNO subscribers was KRW 27,845, about US$19., cash flow and balance sheet Total assets stood at KRW 30.11 trillion and shareholders' equity at KRW 12.96 trillion on December 31, 2025, with cash and equivalents of KRW 1,490.0 billion. Capital expenditure ran KRW 2,206.6 billion in 2025, of which KRW 733.9 billion went into wireless networks, and management expects slightly more in 2026. Translated, total debt sits near US$6.6 billion against roughly US$1.3 billion of cash, giving an enterprise value around US$21.7 billion and EV/EBITDA near 7.6 on approximately US$2.8 billion of EBITDA. Headcount fell to 22,723 at the end of 2025 from 26,195 two years earlier..

MSFT and SKM are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined MSFT and SKM exposure against your real portfolio. It is not an investment adviser.
