CUBE vs PSA: Which Is the Better Buy in 2026?
Last updated September 2026
Short answer
PSA is the larger of the two ($56.56B market cap): the incumbent the market prices for continued execution (29.94x forward earnings, beta 0.94). CUBE is the smaller challenger ($8.99B), cheaper on forward earnings (25.27x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
CUBE vs PSA: the tie-breaker metrics
Same yardstick, side by side (as of September 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 | CUBE | PSA | What it tells you |
|---|---|---|---|
| Market cap | $8.99B | $56.56B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 25.27 | 29.94 | 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. |
| Trailing P/E | 27.03 | 28.90 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 1.06 | 0.94 | 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 | 57% of range | 59% 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 | 3.47 | 10.99 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: CUBE 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 CUBE and PSA 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. CUBE and PSA 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 CUBE and PSA 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 CubeSmart (CUBE) do?
CubeSmart is a self-storage real estate investment trust that owns, operates, and manages hundreds of storage facilities across the United States, concentrated in higher-barrier coastal and major-metro markets. It generates revenue by renting storage units to households and businesses, and it supplements owned-store income with a large third-party management platform that runs facilities for other owners. As a REIT, it passes most of its taxable income to shareholders as dividends, and it has raised that dividend for 16 consecutive years, most recently to an annualized $2.12 per share.
What does Public Storage (PSA) do?
Public Storage is a Maryland-based real estate investment trust (REIT) that acquires, develops, and operates self-storage facilities under the Public Storage brand. As of December 31, 2025, it owned or operated 3,533 self-storage facilities in 40 states encompassing roughly 258 million net rentable square feet, making it one of the two largest self-storage REITs in the United States by property count. The company derives revenue almost entirely from monthly rental income paid by individual and business customers renting climate-controlled and non-climate-controlled storage units. It also holds a 35% common equity interest in Shurgard Self Storage, which operates across seven European countries, providing modest international exposure. Additional income streams include tenant insurance programs, merchandise sales, and a growing third-party property management platform. In 2025, Public Storage acquired 87 facilities totaling 6.1 million square feet for $945.6 million, demonstrating active portfolio expansion alongside organic development. Public Storage was founded in 1972 by B. Wayne Hughes and Kenneth Volk Jr. and grew from a single facility in El Monte, California into the dominant national brand over five decades. The company has been listed on the NYSE as PSA and became an S&P 500 constituent as it scaled. Long-tenured CEO Joe Russell, who led a multi-year operational transformation, retired effective March 31, 2026. Under the PS4.0 initiative, Tom Boyle was elevated to CEO and Shankh Mitra became non-executive chairman effective April 1, 2026, signaling a new strategic phase focused on digital-first operations, margin expansion, and external growth through acquisitions, the first major move being the announced acquisition of National Storage Affiliates Trust.
CUBE vs PSA: 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.
- CUBE drivers: Dividend track record and income appeal; Improving same-store trend off a soft base.
- PSA drivers: Scale and Margin Leadership; NSA Acquisition Adds Immediate Scale.
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: Self-storage demand is sensitive to housing turnover and household moves, and a slow housing market has weighed on new customer move-ins and rate growth. For PSA, the most immediate risk is that same-store revenue is already guided to decline in 2026 (PSA's own guidance calls for same-store NOI growth of negative 3.9% to negative 0.5%), reflecting ongoing supply pressure in Sunbelt and Southeast markets and soft post-pandemic consumer demand.
CUBE or PSA: which should you pick?
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 CUBE if you believe its drivers more; PSA 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 CUBE and PSA guides.
CUBE vs PSA: the full fundamentals
CUBE. CUBE trades around the mid-teens on a price-to-FFO basis, a typical range for a stabilized storage REIT and a discount to larger peers like Public Storage and Extra Space. The reported EPS payout ratio looks stretched (well above 100%) because REIT net income is depressed by heavy real estate depreciation, so FFO and AFFO are the more relevant coverage measures. Guidance for 2026 implies roughly flat FFO per share versus 2025 as improving revenue offsets expense inflation.
PSA. PSA trades at a trailing P/E of roughly 32x, above its own 3-year average of approximately 25x to 27x and above the broader real estate sector average, reflecting the market's expectation that the NSA acquisition and the PS4.0 platform will reaccelerate growth. For REITs, Core FFO per share is the most widely watched profitability metric; PSA's 2025 Core FFO of $16.97 reached the high end of guidance and grew 1.8% year over year, while 2026 guidance of $16.35 to $17.00 implies flat to modestly positive growth. The GAAP payout ratio exceeds 100% of net income, which is normal for REITs given depreciation charges, but the ratio relative to Core FFO is the more relevant measure of dividend coverage.
Headline figures (approximate, July 2026): CUBE shows revenue (ttm) ~$1.1B, q1 2026 revenue ~$282M (up ~3.3% YoY), ffo per share (adjusted, q1 2026) ~$0.63, 2026 ffo/share guidance (adjusted) ~$2.52 to $2.60; PSA shows revenue (ttm) ~$4.85 billion, full-year 2025 revenue ~$4.82 billion, net income (fy 2025) ~$1.78 billion, core ffo per share (fy 2025) ~$16.97.

FAQ
What is the difference between CUBE and PSA?
+
CubeSmart is a self-storage real estate investment trust that owns, operates, and manages hundreds of storage facilities across the United States, concentrated in higher-barrier coastal and major-metro markets. Public Storage is a Maryland-based real estate investment trust (REIT) that acquires, develops, and operates self-storage facilities under the Public Storage brand. 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 CUBE or PSA the better stock?
+
Neither is universally better. PSA is the larger incumbent; CUBE is the smaller challenger and looks cheaper on forward earnings. 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, CUBE or PSA?
+
On forward P/E (as of September 2026), CUBE trades at 25.27x and PSA at 29.94x, so CUBE 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 CUBE and PSA?
+
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 CUBE vs PSA?
+
CUBE: Self-storage demand is sensitive to housing turnover and household moves, and a slow housing market has weighed on new customer move-ins and rate growth. Same-store net operating income was negative through much of 2025 as operating expenses (taxes, payroll, insurance, and weather-related costs) outpaced modest revenue changes. As a REIT, CubeSmart is sensitive to interest rates, which affect both its borrowing costs and the relative attractiveness of its dividend versus bonds. New supply in some markets, promotional discounting to fill units, and a high reported EPS payout ratio are additional pressures. Any renewed weakness in occupancy or street rates would directly slow FFO and could constrain future dividend increases. PSA: The most immediate risk is that same-store revenue is already guided to decline in 2026 (PSA's own guidance calls for same-store NOI growth of negative 3.9% to negative 0.5%), reflecting ongoing supply pressure in Sunbelt and Southeast markets and soft post-pandemic consumer demand. Absorbing more than 1,000 NSA properties through an all-stock deal introduces integration complexity and shareholder dilution, and any delay or regulatory complication in closing the transaction could weigh on the stock. A prolonged high-rate environment increases borrowing costs on PSA's $10.3 billion debt load and compresses REIT valuations broadly, while the GAAP dividend payout ratio above 120% raises the question of how long the current $12.00 annual dividend is sustainable if FFO growth stalls. Regulatory pressure on rents in states like California and rising property tax and insurance costs add further margin headwinds.
