BRK-B vs NCL: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
BRK-B is the larger of the two ($1.10T market cap): the incumbent the market prices for continued execution (23.71x forward earnings, beta 0.61). NCL is the smaller challenger ($8.54M): 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.
BRK-B vs NCL: 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 | BRK-B | NCL | What it tells you |
|---|---|---|---|
| Market cap | $1.10T | $8.54M | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Beta | 0.61 | 0.86 | 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 | 91% of range | 0% 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 | 0.00 | 0.46 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how BRK-B and NCL 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. BRK-B and NCL 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 BRK-B and NCL 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 Berkshire Hathaway (BRK-B) do?
Berkshire Hathaway is a diversified holding company that owns a wide range of businesses outright and holds a large portfolio of public stocks. Its foundation is insurance: GEICO, Berkshire Hathaway Reinsurance, and other insurers generate underwriting profit and, more importantly, float (premiums held before claims are paid) that Berkshire invests. In Q1 2026 insurance underwriting income rose to about $1.72 billion from $1.34 billion a year earlier. Beyond insurance, Berkshire owns the BNSF railroad, Berkshire Hathaway Energy, and consumer and industrial businesses such as Duracell, Dairy Queen, See's Candies, and Precision Castparts, alongside a stock portfolio historically anchored by names like Apple and American Express.
What does Northann Corp (NCL) do?
Northann Corp is a small building-materials company, headquartered in South Carolina, focused on additive manufacturing and 3D-printing technologies for flooring, cabinetry, and other construction and home-improvement products. It sells through a family of brands including Benchwick, SuperOak, DotFloor, and the eco-friendly Blue11, along with proprietary designs such as Infinite Glass, offering substrate-agnostic flooring and wall-panel solutions to retailers in North America. The company emphasizes a portfolio of patents and a focus on sustainable, innovative surface designs as its differentiation in a large but competitive flooring market.
BRK-B vs NCL: 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.
- BRK-B drivers: Leadership transition to Greg Abel; Insurance float and underwriting.
- NCL drivers: 3D-printing and additive-manufacturing differentiation; Brand portfolio and retail distribution.
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: The central 2026 risk is the leadership transition itself: Buffett's judgment and reputation were core to Berkshire's edge, and the market will test whether Greg Abel can allocate capital as effectively, especially with a record cash pile to deploy. For NCL, the dominant risk is that Northann is a very small, speculative micro-cap with a limited revenue base competing against much larger, established flooring manufacturers with far greater scale, distribution, and resources.
BRK-B or NCL: 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 BRK-B if you believe its drivers more; NCL 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 BRK-B and NCL guides.
BRK-B vs NCL: the full fundamentals
BRK-B. Figures are approximate and tied to the asOf date; verify live numbers before acting. Because accounting rules force Berkshire to mark its large stock portfolio to market each quarter, GAAP net income is noisy, so investors typically focus on operating earnings and book value per share rather than a simple P/E. The record cash balance means a meaningful part of the market cap is cash awaiting deployment, which affects how the business should be valued.
NCL. Figures are approximate and tied to the asOf date; verify live numbers before acting. For a speculative micro-cap like Northann, standard valuation metrics are of limited use because the revenue base is small, profitability is inconsistent, and the share count can change with dilution. The stock trades on sentiment about its 3D-printing story, its ability to scale, and its listing status rather than stable earnings. Its thin trading makes prices volatile and easily moved, so treat any implied valuation with caution and as a high-risk bet.
Headline figures (approximate, Jul 2026): BRK-B shows operating earnings (q1 2026) ~$11.35 billion, up ~18% year over year (approximate; verify live), net earnings (q1 2026) ~$10.1 billion, but volatile due to mark-to-market swings on equities (approximate; verify live), cash and treasurys ~$397 billion at end of Q1 2026, a record (approximate; verify live), market cap ~$1 trillion (BRK-B ~$497 per share in mid-July 2026; approximate; verify live); NCL shows company profile Micro-cap building-materials firm using 3D printing and additive manufacturing, revenue base Small; a niche flooring and wall-panel business, not yet at meaningful scale, profitability Has faced losses and share dilution as a small, early-stage manufacturer, listing status Regained full NYSE American continued-listing compliance in June 2026.
The bottom line: BRK-B vs NCL
BRK-B and NCL 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 BRK-B and NCL exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between BRK-B and NCL?
+
Berkshire Hathaway is a diversified holding company that owns a wide range of businesses outright and holds a large portfolio of public stocks. Northann Corp is a small building-materials company, headquartered in South Carolina, focused on additive manufacturing and 3D-printing technologies for flooring, cabinetry, and other construction and home-improvement products. 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 BRK-B or NCL the better stock?
+
Neither is universally better. BRK-B is the larger incumbent; NCL is the smaller challenger. 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, BRK-B or NCL?
+
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 BRK-B and NCL?
+
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 BRK-B vs NCL?
+
BRK-B: The central 2026 risk is the leadership transition itself: Buffett's judgment and reputation were core to Berkshire's edge, and the market will test whether Greg Abel can allocate capital as effectively, especially with a record cash pile to deploy. Size is another constraint: at roughly a trillion dollars in market value, Berkshire needs very large deals to move the needle, which limits its universe of opportunities and can hold cash idle. The insurance business carries catastrophe risk, as large wildfire and disaster losses have shown in recent years, and results can swing on a single bad quarter. The reported net income is volatile because accounting rules force Berkshire to mark its huge equity portfolio to market each quarter, so headline profit can gyrate on stock-price moves even when the operating businesses are steady. Berkshire also pays no dividend, so all returns must come from price appreciation and buybacks. NCL: The dominant risk is that Northann is a very small, speculative micro-cap with a limited revenue base competing against much larger, established flooring manufacturers with far greater scale, distribution, and resources. The company has faced losses and share dilution, and as a small firm it may need additional capital, which could further dilute existing shareholders. Its recent history includes a listing-compliance deficiency that it only regained compliance on in June 2026; any renewed failure to meet NYSE American standards could threaten its listing and liquidity. The stock is thinly traded and illiquid, which makes it highly volatile and vulnerable to large price swings on small volumes. Its 3D-printing approach is unproven at large scale in a competitive commodity-like flooring market, and there is execution risk in winning and keeping retail placement. Housing-market and construction cycles, input costs, and broad economic conditions add further uncertainty. This is a high-risk holding suited only to investors who can tolerate the possibility of significant loss.
