The line below covers up to 5.2 years and opens on the 5Y view; the buttons cut it shorter. Over the last two years (104 weeks) this industry is 41% behind S&P 500. Earnings across its companies fell 46% on average over the last four reported quarters.

Price down, no fundamental support. 1 of 5 companies ahead of S&P 500 by 5% or more over three months.

Not ahead of S&P 500 on the three-month view this week; 1 of the 5 companies in the industry index above their 200-day average (no change from four weeks earlier); 1 of those 5 ahead of S&P 500 by 5% or more over three months (no change from four weeks earlier); earnings rising at 1 of the 5 that report earnings.

Behind S&P 500 by −25.5% over a year, with participation off the floor of its own 26-week range. Earnings not confirming, 1 of 5 members have higher trailing twelve-month earnings than a year ago.

Both lines start at 200 in the same week, so the gap between them tells the story: the industry line is an equal-weighted index of its 5 companies. The bars underneath are trailing 12-month earnings per share, one bar per reported quarter, each member set to 100 at the start and the industry taking the middle value, so a price line pulling away from flat bars means the market is paying more for the same earnings. A bar turns grey when that figure is lower than the quarter before. The rules are fixed and the same everywhere on this site: ahead by 5% or more over three months, or behind by 20% or more over a year while earnings grew 20% or more. Hover or tap any point to read both values and the gap.

Thermal Coal has done worse than the S&P 500 by 22.6% over the last 52 weeks. Over 13 weeks the gap is a shortfall of 8.8%. Natural Resource Partners L.P. is the strongest against the sector itself at +24.8%.

A score that ranks each company against the others in its industry. The four parts shown always add up to the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or old evidence affects only its own part, never as a hidden adjustment.

Alliance Resource Partners, L.P. has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 85.3% evidence confidence.

Natural Resource Partners L.P. scores well on valuation against its peers or its own history, but its earnings have not yet improved enough to back that up.

Natural Resource Partners L.P. has the strongest one-year price move in Thermal Coal at +12.3%. It also leads on relative strength against the S&P 500, at +0.5%. 1 of 5 companies we track is ahead of the index on that measure. Every line covers 314 weekly closes through 4 November 2026.

Price and relative strength

Price · same starting point: Every company, the sector's own index and S&P 500 all start level on the left edge of the window, so only the distance between the lines counts: the highest line has risen the most since then, and the chart at the top of this page is drawn the same way. It opens on one year; the buttons beside it stretch that to three or five.

RS vs S&P 500: How far ahead of or behind S&P 500 each company has been running, measured against its own recent average of that comparison, so the flat line at zero IS S&P 500: above it the company is beating the market, below it the market is beating the company. It opens on one year.

RS vs sector: The same measure taken against Thermal Coal itself instead of the whole market, so the flat line at zero is the sector: above it the company is beating its own peers, which is the sharper test of the two. It opens on one year.

Core Natural Resources, Inc. has the highest Revenue among the 5 Thermal Coal companies compared here, at $4,270 million. Peabody Energy Corporation is next at $4,010 million. The same company also has the highest Revenue growth, at 31.6%. 5 of 5 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Core Natural Resources, Inc. is the largest at $4,270 million, 6.5% ahead of Peabody Energy Corporation. Core Natural Resources, Inc.'s growth is 31.6% from a $4,270 million base, with 20 reported quarters out of the last 20. Fast growth from a smaller base is not yet the same as proven size.

What this means: Core Natural Resources, Inc. is both the largest and the fastest-growing company here; the growth has to turn into margin and returns before it counts as more than a fast start.

This conclusion weakens if: Core Natural Resources, Inc.'s revenue growth slows for two consecutive comparable reports while its operating margin also compresses.

Revenue is compared on a common reported-currency basis. Growth is year-on-year, so seasonality does not masquerade as progress.

All-company data · latest reported quarter

In every all-company table on this page, each figure is the company’s latest single reported quarter. The rankings above them use trailing-twelve-month or current-market values, so a company can legitimately show a different number in each.

Revenue shows both size and speed. A large company can absorb shocks and pay for wide distribution; faster growth can mean market-share gains, new capacity or stronger demand. The best sign is usually growth that lasts without hurting margins and returns.

Natural Resource Partners L.P. has the highest OPM among the 5 Thermal Coal companies compared here, at 58.7%. Alliance Resource Partners, L.P. is next at 17%. NACCO Industries, Inc. has the highest Margin change at +13.6 percentage points, so level and change sit with different companies. 5 of 5 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Natural Resource Partners L.P. leads opm at 58.7%; NACCO Industries, Inc. leads margin change at +13.6 percentage points.

What this means: Natural Resource Partners L.P. sets the level to compare against; the company improving fastest needs another report to confirm the change.

This conclusion weakens if: The next two comparable reports reverse the current margin change signal.

Operating margin compares operating profit with revenue. Improvement is measured in percentage points, not percentage growth.

Alliance Resource Partners, L.P. has the highest Net profit among the 5 Thermal Coal companies compared here, at $263 million. Natural Resource Partners L.P. is next at $107 million. The same company also has the highest Profit growth, at 12.4%. 5 of 5 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Alliance Resource Partners, L.P. earns the most, $263 million of profit over the last 12 months, 145.8% above Natural Resource Partners L.P. A fast rate from a small base matters less than a large profit that keeps coming.

What this means: Alliance Resource Partners, L.P. sets the level to compare against; the company improving fastest needs another report to confirm the change.

This conclusion weakens if: The next two comparable reports reverse the current profit growth signal.

Net profit is the residual after operating costs, interest and tax. Growth off a loss or near-zero base is excluded from the fastest-grower rank.

Natural Resource Partners L.P. has the highest ROCE among the 5 Thermal Coal companies compared here, at 17.5%. Alliance Resource Partners, L.P. is next at 13.5%. NACCO Industries, Inc. has the highest ROCE change at +3.2 percentage points, so level and change sit with different companies. 5 of 5 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Natural Resource Partners L.P. leads ROCE at 17.5%, 4 percentage points above Alliance Resource Partners, L.P. A high return reported once may be one good year; a high return reported year after year shows a lasting business.

What this means: Natural Resource Partners L.P. sets the level to compare against; the company improving fastest needs another report to confirm the change.

This conclusion weakens if: The next two comparable reports reverse the current roce change signal.

ROCE asks how much operating return the business earns on the capital employed. Direction matters, but a single exceptional year should not be mistaken for durability.

Core Natural Resources, Inc. has the lowest PEG among the 5 Thermal Coal companies compared here, at 0.09×. Natural Resource Partners L.P. is next at 0.11×. Peabody Energy Corporation has the lowest P/E at −68.3×, so level and change sit with different companies. 4 of 5 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Core Natural Resources, Inc. has the lowest comparable PEG at 0.09×, 18.2% below Natural Resource Partners L.P. That would need today's multiple, the company's own history and steady growth to agree.

What this means: A low valuation is a reason to look closer at the business, not a conclusion on its own.

This conclusion weakens if: The next two comparable reports reverse the current p/e signal.

PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is worked out the same way every time, as the P/E on the last 12 months of reported earnings divided by that growth rate, never on expected earnings. On Indian companies it is shown only where the two data feeds agreed. Where any of that fails the ratio is left out rather than printed: a P/E divided by a loss, or by growth measured off a tiny base, is a number that looks precise and means nothing.

This Thermal Coal comparison names 4 specific ways its own evidence can mislead, all listed below. All 5 companies here report on comparable dates, so no rank carries a stale marker. A high growth rate can still come from a very small starting figure.

Keep these limits visible

• A high growth rate can come from a very small starting figure. The page keeps level and change separate for that reason.
• A high ROCE can be temporary, or look high because the capital base is small. It is best read beside margin, cash flow and how much is spent back on the business.
• The 4-Factor Sector Score ranks published data only. Management quality, upcoming events and risks are not part of it.
• An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.

This comparison is built from the reported filings of 5 Thermal Coal companies, normalized to a common $ scale and a shared quarter axis of up to 20 quarters each. Fundamentals run through Jun 2026 and market data through 4 November 2026.

These 21 answers restate the Thermal Coal comparison above in question form. Every one is computed from the same 5 companies and the same reported filings as the rankings and charts, current through Jun 2026. Price and relative-strength answers run through 4 November 2026. Nothing here is estimated, and none of it is a recommendation.
