AG vs FSM: How AG and FSM Compare (2026)
Last updated July 2026
Short answer
AG is the larger of the two ($8.47B market cap): the incumbent the market prices for continued execution (14.86x forward earnings, beta 2.11). FSM is the smaller challenger ($2.58B), cheaper on forward earnings (5.09x): 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 FSM: the tie-breaker metrics
Same yardstick, side by side (as of July 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 | FSM | What it tells you |
|---|---|---|---|
| Market cap | $8.47B | $2.58B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 14.86 | 5.09 | 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 | 29.08 | 7.89 | 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 | 2.12 | 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 | 39% of range | 31% 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 | 2.93 | 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: FSM 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 FSM 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 FSM 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 FSM 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 AG (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 FSM (FSM) do?
Fortuna Mining Corp. (formerly Fortuna Silver Mines) is a Canada-based, mid-tier precious and base metals producer that trades on the NYSE and TSX. Its ongoing operations are the Seguela gold mine in Cote d'Ivoire (its flagship, lowest-cost asset), the Lindero gold heap-leach mine in Argentina, and the Caylloma silver, zinc and lead mine in Peru. Over 2025 the company reshaped its portfolio, selling the San Jose silver mine in Mexico and the Yaramoko gold mine in Burkina Faso to shed higher-cost, shorter-life assets and concentrate on lower-cost gold ounces. It is also advancing the Diamba Sud gold project in Senegal as its next growth engine.
AG vs FSM: 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.
- FSM drivers: Gold price leverage and record cash flow; Seguela as the low-cost flagship.
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 FSM, fSM's mines sit in jurisdictions with meaningful political, tax and regulatory risk, including Argentina, Peru, Cote d'Ivoire and Senegal, where currency controls, permitting delays or fiscal changes can hit economics.
AG or FSM: 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; FSM 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 FSM guides.
AG vs FSM: 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.
FSM. FSM trades at a low single-digit to high single-digit earnings multiple, a discount to the roughly 14x average for US metals and mining, reflecting both jurisdictional risk and the market's tendency to price gold miners cautiously into a high gold-price cycle. The company carries net cash of about ~$493 million and generates strong free cash flow, but pays no dividend, so returns depend on the gold price and execution of its production growth plan. Valuation multiples for gold miners can compress fast if gold prices fall, so the low multiple reflects cyclicality rather than a simple bargain.
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; FSM shows revenue (ttm) ~$1.09 billion, q1 2026 revenue ~$342 million (record), net income (ttm) ~$340 million, market cap ~$2.5 billion.
The bottom line: AG vs FSM
AG and FSM 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 FSM exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between AG and FSM?
+
First Majestic Silver Corp. Fortuna Mining Corp. 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 FSM the better stock?
+
Neither is universally better. AG is the larger incumbent; FSM 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, AG or FSM?
+
On forward P/E (as of July 2026), AG trades at 14.86x and FSM at 5.09x, so FSM 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 FSM?
+
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 FSM?
+
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. FSM: FSM's mines sit in jurisdictions with meaningful political, tax and regulatory risk, including Argentina, Peru, Cote d'Ivoire and Senegal, where currency controls, permitting delays or fiscal changes can hit economics. The stock is highly sensitive to the gold price, so a sustained pullback in gold would compress margins and cash flow quickly. Mine depletion is an ongoing concern; each asset has a finite reserve life, and the growth plan depends on successful exploration and project execution. Concentration in a small number of mines means a single operational disruption, strike or grade shortfall can move consolidated results materially. As a metals producer, it also faces rising labor, energy and input costs that can erode the benefit of high gold prices.
