AG vs B: Which Is the Better Buy in 2026?
Last updated September 2026
Short answer
B is the larger of the two ($70.94B market cap): the incumbent the market prices for continued execution (9.83x forward earnings, beta 1.11). AG is the smaller challenger ($9.79B), actually pricier on forward earnings (19.52x): 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.
AG vs B: 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 | AG | B | What it tells you |
|---|---|---|---|
| Market cap | $9.79B | $70.94B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 19.52 | 9.83 | 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 | 28.37 | 11.14 | 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 | 2.11 | 1.11 | 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 | 47% of range | 58% 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 | 3.30 | 2.60 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: B 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 AG and B 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. AG and B 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 AG and B 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 First Majestic Silver Corp (AG) do?
First Majestic Silver Corp. (NYSE: AG) is a precious-metals producer that operates four underground mines in Mexico: San Dimas in Durango, Santa Elena in Sonora, La Encantada in Coahuila, and Cerro Los Gatos in Chihuahua. The company mines silver and gold as its primary products, along with byproduct zinc, lead, and copper. In January 2025 First Majestic completed its roughly $1.05 billion all-stock acquisition of Gatos Silver, adding a 70% interest in the Los Gatos joint venture and lifting 2025 silver production to a record 15.4 million ounces, up about 84% from the prior year.
What does Barrick Mining Corporation (B) do?
Barrick Mining Corporation (B) is one of the world's largest gold producers and, increasingly, a major copper producer. It mines and sells gold and copper from a portfolio of large, long-life operations spread across the Americas, Africa, and the Middle East, including Nevada Gold Mines (a joint venture in the United States), Pueblo Viejo in the Dominican Republic, Kibali in the Democratic Republic of Congo, and the Loulo-Gounkoto complex in Mali. The company changed its name from Barrick Gold Corporation to Barrick Mining Corporation and switched its NYSE ticker from GOLD to B in May 2025, reflecting its push to grow copper alongside gold. Its growth pipeline includes the Fourmile gold project in Nevada and the large Reko Diq copper-gold project in Pakistan. As a commodity producer, Barrick's revenue and profits swing with gold and copper prices, which it does not control. Its shares also trade on the Toronto Stock Exchange under ABX. Headquartered in Toronto, Barrick is widely viewed as a large-cap way to gain exposure to gold as a store of value, with growing copper leverage to electrification.
AG vs B: 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.
- AG drivers: Silver and gold price leverage; Los Gatos integration and scale.
- B drivers: Large-cap gold exposure; Growing copper and the energy transition.
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 single largest risk is the silver price itself: a sustained decline would compress margins far faster than the metal falls because mining costs are largely fixed. For B, barrick is a commodity producer, so its revenue and profits swing sharply with gold and copper prices, which it does not control and which can fall in stronger-growth or higher-real-rate environments.
AG or B: 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 AG if you believe its drivers more; B 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 AG and B guides.
AG vs B: the full fundamentals
AG. First Majestic posted record Q1 2026 revenue of about $476.7 million, up roughly 95% year over year, with net earnings near $128 million and EPS around $0.26 as silver and gold prices surged. The stock trades at a trailing P/E in the low 30s and a forward P/E near 18, reflecting expectations that elevated metal prices continue. The dividend yield is negligible (well under 1%), so the return case rests almost entirely on the metal price and production.
B. Barrick's valuation is inherently cyclical because earnings move with gold and copper prices the company does not control. A normal P/E can look low near the top of the metals cycle and high or not meaningful near the bottom, so the stock often trades on the gold and copper price outlook rather than on trailing earnings. In 2025 Barrick generated roughly $17 billion of revenue and about $3.9 billion of free cash flow and returned a company-record amount to shareholders through dividends and buybacks. Figures are approximate and move sharply with commodity prices; verify current numbers before relying on them.
Headline figures (approximate, Q1 2026): AG shows q1 2026 revenue ~$477M, q1 2026 net earnings ~$128M, q1 2026 eps ~$0.26, q1 2026 free cash flow ~$224M; B shows revenue (fy2025) ~$17 billion (varies with metal prices), primary products gold, with a growing copper business, gold production (fy2025) ~3.3 million ounces, copper production (fy2025) ~220,000 tonnes (a company record).
The bottom line: AG vs B
AG and B 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 AG and B exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between AG and B?
+
First Majestic Silver Corp. Barrick Mining Corporation (B) is one of the world's largest gold producers and, increasingly, a major copper producer. 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 AG or B the better stock?
+
Neither is universally better. B is the larger incumbent; AG is the smaller challenger and looks pricier 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, AG or B?
+
On forward P/E (as of September 2026), AG trades at 19.52x and B at 9.83x, so B 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 AG and B?
+
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 AG vs B?
+
AG: The single largest risk is the silver price itself: a sustained decline would compress margins far faster than the metal falls because mining costs are largely fixed. Geographic concentration is severe, with essentially all production in Mexico, exposing the company to peso currency swings, mining royalty and tax changes, permitting delays, and local security or labor disruptions. Rising input costs (energy, labor, consumables) can erode margins even when metal prices are steady. As a smaller producer than majors like Pan American or Fresnillo, AG has less operational diversification to absorb a single mine outage. The stock has historically been highly volatile and can move on sentiment and short interest as much as on fundamentals. B: Barrick is a commodity producer, so its revenue and profits swing sharply with gold and copper prices, which it does not control and which can fall in stronger-growth or higher-real-rate environments. Its mines are spread across jurisdictions with meaningful political, regulatory, tax, and security risk, including a well-publicized dispute with the government of Mali over the Loulo-Gounkoto complex and security reviews at the Reko Diq project in Pakistan. Mining is capital intensive and carries operational, environmental, and permitting risks, and costs can rise with energy and labor inflation. The stock is cyclical and can be volatile, and it is a commodity-leveraged position rather than a steady income or defensive holding.
