IT vs PENG: 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: IT 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. IT and PENG 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 IT and PENG 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. Walnut is not an investment adviser.

Gartner, Inc. is the world's largest independent technology research and advisory firm, selling syndicated research, analyst access, benchmarking, and advisory relationships to IT, finance, HR, supply-chain, and other corporate leaders. It operates through three segments: Business and Technology Insights (formerly Research), which is nearly 100% subscription-based and is the profit engine; Conferences, the in-person events business that ran 53 conferences with over 83,000 attendees in 2025; and Consulting, a smaller project-based advisory arm. The economics are attractive because Insights carries high gross margins, high renewal rates, and predictable recurring revenue tied to contract value (the annualized value of subscription contracts), which management watches as the core growth metric.

Penguin Solutions, Inc. (NASDAQ: PENG) is the company formerly known as SMART Global Holdings (SGH), which rebranded in October 2024 to reflect a pivot from being seen as a specialty-memory manufacturer to a provider of end-to-end AI and high-performance computing infrastructure. It designs, builds, deploys, and manages large compute clusters through its Advanced Computing segment (branded Penguin Computing, Stratus, and the OriginAI AI-factory platform), sells specialty memory modules through its Integrated Memory segment, and runs a smaller Optimized LED business under the Cree LED brand. In practice it acts as an architect and operator of AI data centers, bundling hardware, infrastructure software, and services rather than competing head-on as a pure component maker.

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

• IT drivers: Subscription research and contract value; Cash generation and buybacks.
• PENG drivers: Riding the AI data-center buildout; SK Telecom and SK hynix alliance.

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 dominant risk is generative AI disintermediation: if free or cheaper AI tools can approximate the research and advice clients pay Gartner for, subscription demand and pricing power could erode, which is the primary reason the stock derated so sharply in 2026. For PENG, the most concrete risk is customer concentration: Penguin's top ten end customers accounted for about 66% of net sales in fiscal 2025 (up from 58% in 2024), and two individual customers each exceeded 10% of sales, so the loss or pullback of a single large buyer could sharply dent revenue and hand those customers pricing leverage.

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 IT if you believe its drivers more; PENG 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 IT and PENG guides.

IT. Gartner traded around $140 in early-to-mid July 2026, down roughly two-thirds from a 52-week high above $400, which pushed the trailing P/E down near 13 against a five-year median above 30. The compression reflects fear that AI erodes the research franchise plus slowing contract-value growth, not a collapse in current profits, since cash flow and EPS actually rose. Analyst price targets clustered around the mid-$160s, implying the Street sees the selloff as partly overdone but keeps a cautious consensus.

PENG. Figures are approximate and tied to the July 2026 asOf date; verify live numbers before acting. Trailing net income is small relative to a ~$3.2 billion market cap, so headline trailing P/E ratios look extreme and are not a useful gauge; the market is valuing forward AI-infrastructure growth, not current earnings. The stock's more-than-200% three-month run means the valuation already prices in substantial optimism about the AI-factory strategy.

Headline figures (approximate, JULY 2026): IT shows revenue (ttm) ~$6.5B, q1 2026 revenue ~$1.51B (-1.5% YoY), q1 2026 diluted eps ~$3.18 (+17% YoY), q1 2026 free cash flow ~$371M (+29% YoY); PENG shows revenue (ttm) ~$1.4 billion, fiscal q2 2026 net sales ~$343 million (down ~6% year over year), market cap ~$3.2 billion, stock price ~$68 per share.

IT and PENG 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 IT and PENG exposure against your real portfolio. It is not an investment adviser.
