ACB vs CGC: Which Is the Better Buy in 2026?
Last updated October 2026
Short answer
CGC is the larger of the two ($320.35M market cap): the incumbent the market prices for continued execution (-5.96x forward earnings, beta 2.37). ACB is the smaller challenger ($252.61M), priced similarly on forward earnings (-36.27x): 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.
ACB vs CGC: the tie-breaker metrics
Same yardstick, side by side (as of October 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 | ACB | CGC | What it tells you |
|---|---|---|---|
| Market cap | $252.61M | $320.35M | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | -36.27 | -5.96 | 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 | 1.42 | 2.37 | 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 | 38% of range | 1% 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 | 0.68 | 0.62 | 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 ACB and CGC 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. ACB and CGC 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 ACB and CGC 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 Aurora Cannabis (ACB) do?
Aurora Cannabis is a Canadian licensed cannabis producer that has spent the past several years reinventing itself. Once one of the most hyped names of the 2018-2019 cannabis boom, it has since exited low-margin Canadian consumer (recreational) cannabis and non-core operations to concentrate on global medical cannabis, which carries higher and more durable margins. In its fiscal 2026 (ended March 31, 2026) the company reported record medical results: global medical net revenue grew sharply, international medical revenue rose even faster (led by Germany and Poland), and adjusted EBITDA and free cash flow were positive, a real shift from years of cash burn. On a GAAP basis, however, Yahoo Finance data show fiscal 2026 revenue of about 321 million and a net loss of about 122 million (Canadian dollars), with large losses in two quarters. International medical, its highest-margin segment, now makes up a majority of medical revenue. To feed that demand, Aurora acquired Safari Flower Company, an EU-GMP certified European cultivator, completed the divestiture of its controlling stake in Bevo Agtech in February 2026, and in October 2026 finished an expansion of its European EU-GMP facility that it says more than doubles expected annual flower output.
What does Canopy Growth Corporation (CGC) do?
Canopy Growth Corporation is one of Canada's largest cannabis companies, based in Smiths Falls, Ontario. It sells recreational (adult-use) and medical cannabis in Canada, exports medical cannabis to international markets in Europe and Australia, and owns Storz & Bickel, a maker of premium vaporizer devices. Its revenue comes mainly from selling cannabis flower, pre-rolls, vapes, edibles, and beverages under brands like Tweed and Doja, plus device sales. In fiscal 2026 the company completed its acquisition of MTL Cannabis, a move it says makes it Canada's leading medical-cannabis provider by revenue, and reported that its core cannabis business returned to growth after years of contraction.
ACB vs CGC: 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.
- ACB drivers: International medical cannabis growth; The Curaleaf bid and strategic review.
- CGC drivers: Core cannabis business back to growth; MTL Cannabis and medical leadership.
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 risk is Aurora's capital-structure history: repeated equity raises and a cumulative reverse-split history (roughly 1-for-120 over time) have destroyed per-share value, and further dilution would do so again. For CGC, the central risk is that Canopy is still unprofitable in a brutally competitive industry.
ACB or CGC: 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 ACB if you believe its drivers more; CGC 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 ACB and CGC guides.
ACB vs CGC: the full fundamentals
ACB. Aurora trades below book value and under one times sales, a discount that tracks its losses and dilution history, but in October 2026 the price is also being set by the Curaleaf bid: the shares sit about 20% below the roughly $5 headline offer, since most of that value is in Curaleaf stock and the board opposes it. Be cautious with per-share comparisons across time given the reverse-split history, and check the current share count, cash position, and the status of the offer directly in filings. Fiscal second-quarter results are expected in early November 2026.
CGC. Because Canopy is unprofitable, earnings multiples do not apply, and at about 1.1 times sales and well under book value the market is pricing in real doubt that the turnaround reaches profit. Reported financials are in Canadian dollars, so US-dollar comparisons move with exchange rates. Treat any single quarter with caution: cannabis results swing on pricing, one-time charges and restructuring, and the next report lands November 6, 2026.
Headline figures (approximate, October 2026): ACB shows market cap ~$252M at ~$3.98 a share (Oct 16, 2026), revenue (ttm) ~314M (Canadian dollars), down ~9% YoY in the latest quarter, net income (ttm) ~-52M; Q1 FY2027 net loss only ~-4M, eps (latest quarter) ~-$0.07 vs ~-$0.21 estimate; CGC shows revenue (ttm) ~$294 million (reported in Canadian dollars), with the June 2026 quarter up ~12.5% year over year, latest quarter (june 2026) Revenue ~$81 million; loss per share $0.02 vs $0.03 expected, margins Gross ~28.5%; operating ~-22%; still net-loss-making, net income (ttm) ~-$233 million; trailing EPS ~-$0.42.

FAQ
What is the difference between ACB and CGC?
+
Aurora Cannabis is a Canadian licensed cannabis producer that has spent the past several years reinventing itself. Canopy Growth Corporation is one of Canada's largest cannabis companies, based in Smiths Falls, Ontario. 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 ACB or CGC the better stock?
+
Neither is universally better. CGC is the larger incumbent; ACB 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, ACB or CGC?
+
On forward P/E (as of October 2026), ACB trades at -36.27x and CGC at -5.96x, so ACB 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 ACB and CGC?
+
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 ACB vs CGC?
+
ACB: The central risk is Aurora's capital-structure history: repeated equity raises and a cumulative reverse-split history (roughly 1-for-120 over time) have destroyed per-share value, and further dilution would do so again. The takeover contest adds a new kind of volatility: if Curaleaf's offer lapses or is withdrawn and no alternative deal emerges, the shares could give back much of the roughly 49% three-month gain, while holders who tender would mostly receive Curaleaf stock, carrying that company's own risks. Even after the medical turnaround, management guided fiscal 2027 EBITDA lower, partly due to reduced Canadian medical reimbursement rates from April 2026, and revenue fell about 9% year over year in the June 2026 quarter. As a small-cap in a small, fast-changing industry, Aurora is heavily exposed to regulation: a policy change in Germany, Poland, Canada, or any key market can swing results quickly, and the whole sector is prone to sharp sentiment-driven moves. Currency swings between the Canadian dollar, euro, and US dollar affect reported results. Competition from Tilray, Canopy Growth, Curaleaf and local European producers is intense. The shares are volatile and speculative, and the stock has no dividend. CGC: The central risk is that Canopy is still unprofitable in a brutally competitive industry. Canadian adult-use cannabis suffers from oversupply and price compression, which squeezes margins even as volumes grow. The company has a long history of large writedowns (BioSteel, Wana, and others) and heavy share dilution, so existing shareholders have repeatedly been diluted to fund losses. Its US upside through Canopy USA depends on federal reform that has been promised for years without arriving, and remains outside the company's control. Canopy also restated prior-period financials for non-cash technical errors tied to certain US-dollar share-settled warrants. As a small-cap cannabis stock, CGC is highly volatile and sensitive to sentiment, financing conditions, and regulatory headlines, with no guarantee the turnaround reaches sustained profitability. A newer risk is the share price itself: CGC closed at $0.74 on October 16, 2026, and Nasdaq rules require a minimum $1 bid price, so a prolonged stretch below $1 could bring a deficiency notice and another reverse split, as the company has done before.
