CDNS vs IP: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
CDNS and IP are similarly sized, but IP trades noticeably cheaper on forward earnings (13.89x vs 35.65x): the market is paying up for CDNS's profile and pricing IP more conservatively, or for faster growth. Which you prefer comes down to the drivers you believe, and whether adding either over-concentrates what you already own.
CDNS vs IP: the tie-breaker metrics
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.
| Metric | CDNS | IP | What it tells you |
|---|---|---|---|
| Forward P/E | 35.65 | 13.89 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Beta | 1.15 | 0.90 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 50% of range | 55% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 13.58 | 1.46 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: IP 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.
Before you buy: how CDNS and IP affect your concentration
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. CDNS and IP 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 CDNS and IP 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.

What does Cadence Design Systems (CDNS) do?
Cadence Design Systems makes electronic design automation (EDA) software, intellectual property (IP) blocks, and hardware systems that semiconductor and systems companies use to design, simulate, and verify chips before they are manufactured. Its tools sit at the front of the chip supply chain, so nearly every advanced processor, from data-center AI accelerators to smartphone and automotive chips, is designed with software from Cadence or its main rival Synopsys. The business is heavily recurring and subscription-based, which produces high margins, strong free cash flow, and unusually predictable revenue backed by a multi-year order backlog.
What does International Paper (IP) do?
International Paper is a leading global producer of fiber-based packaging, pulp, and related products, best known for corrugated containers and the containerboard that goes into them. Its boxes carry everything from food and beverages to e-commerce shipments and industrial goods, so demand broadly tracks consumer and industrial activity. The company sells mainly to businesses rather than consumers, and its economics turn on containerboard pricing, box volumes, input costs like fiber and energy, and mill utilization. As a large, capital-intensive manufacturer, it competes on cost, scale, and its distribution and converting network.
CDNS vs IP: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- CDNS drivers: AI and design complexity; Recurring revenue and backlog.
- IP drivers: DS Smith integration and global scale; Cost cuts and footprint optimization.
Which fits which kind of investor
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: Valuation is the most immediate risk: CDNS trades at rich trailing and forward multiples that price in sustained high growth, so any deceleration or guidance miss can trigger sharp drawdowns. For IP, the main risk is cyclicality: box volumes and containerboard pricing move with consumer and industrial activity, so an economic slowdown can reduce demand and pressure pricing and margins, as recent low-single-digit volume softness showed.
CDNS or IP: which should you pick?
CDNS vs IP: the full fundamentals
CDNS. Cadence grew revenue about 19% year over year in Q1 2026 with non-GAAP operating margin near 45%, and raised its full-year outlook to roughly 17% growth. The stock carries a premium valuation, with a forward P/E in the mid-40s and an even higher trailing multiple, reflecting its recurring model and AI-linked demand. Figures are approximate and drawn from company reports and market data as of July 2026.
IP. Figures are approximate and tied to the asOf date; verify live numbers before acting. Packaging producers like International Paper are cyclical, so trailing earnings can be distorted by restructuring charges and where box volumes and containerboard prices sit in the cycle. That makes forward margins, synergy capture, and the value the market assigns to the two separated companies more important to the thesis than a single point-in-time earnings multiple.
Headline figures (approximate, July 2026): CDNS shows revenue (ttm) ~$5.5B, q1 2026 revenue ~$1.47B (up ~19% YoY), q1 2026 non-gaap eps ~$1.96, backlog ~$8.0B (record); IP shows transformation Completed DS Smith acquisition (Jan 2025); planned geographic split announced early 2026, synergy target At least several hundred million dollars from the DS Smith combination, 2025 segment strength North American packaging adjusted EBITDA grew sharply with margin expansion, 2026 earnings Expected to absorb substantial restructuring charges from footprint actions.
The bottom line: CDNS vs IP
CDNS and IP 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 CDNS and IP exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between CDNS and IP?
+
Cadence Design Systems makes electronic design automation (EDA) software, intellectual property (IP) blocks, and hardware systems that semiconductor and systems companies use to design, simulate, and verify chips before they are manufactured. International Paper is a leading global producer of fiber-based packaging, pulp, and related products, best known for corrugated containers and the containerboard that goes into them. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is CDNS or IP the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, CDNS or IP?
+
On forward P/E (as of August 2026), CDNS trades at 35.65x and IP at 13.89x, so IP is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both CDNS and IP?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of CDNS vs IP?
+
CDNS: Valuation is the most immediate risk: CDNS trades at rich trailing and forward multiples that price in sustained high growth, so any deceleration or guidance miss can trigger sharp drawdowns. Geopolitical exposure is material, as US export controls on EDA software to China can be tightened or loosened with little warning and China is a meaningful revenue source. The underlying semiconductor industry is cyclical, and a downturn in chip capital spending would slow bookings. Long-term, Chinese domestic EDA vendors are being pushed as homegrown alternatives, though their current share is very small. Finally, concentration in a handful of large chip and systems customers means lumpy hardware orders can create quarter-to-quarter noise. IP: The main risk is cyclicality: box volumes and containerboard pricing move with consumer and industrial activity, so an economic slowdown can reduce demand and pressure pricing and margins, as recent low-single-digit volume softness showed. The transformation adds substantial execution risk: integrating DS Smith, capturing synergies, and separating into two companies all carry costs, distraction, and the possibility of dis-synergies or delays. Heavy restructuring charges are expected to weigh on 2026 earnings even as they set up future savings. Input costs for fiber, energy, and chemicals are volatile and can compress margins. The business is capital intensive and carries debt increased by the DS Smith deal, so higher rates raise financing costs. Trade policy, tariffs, and currency swings add further uncertainty across its now larger international footprint.
