Thermal Coal, equal-weighted, based at 200 S&P 500, same base, same start trailing 12-month earnings per share rising falling

Both lines start at 200 in the same week, so the distance between them is the whole 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 rebased to 100 at the start and the industry taking the median — so a price line pulling away from flat bars is a re-rating, not earnings. A bar turns red when that figure is lower than the quarter before. Rules are fixed and applied identically 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 any point to read both values and the gap. This is a description of what the numbers did, not advice.

02 · sector relative strength, before individual stocks

Is Thermal Coal outperforming S&P 500?

Thermal Coal has underperformed S&P 500 by 4.2% over the last 52 weeks. Over 13 weeks the gap is a shortfall of 8.8%. 0 of 5 covered companies currently beat the S&P 500 on Mansfield relative strength, so leadership inside the sector is selective. Alliance Resource Partners, L.P. is the strongest against the sector itself at +8.7%.

The central tension: current leadership is concentrated, so durability matters more than rank.

Start with scale. Then earnings trajectory. Then business quality. Only after those three agree should price leadership carry much weight.

Bottom line

Thermal Coal has underperformed S&P 500 by 4.2% over 52 weeks and 8.8% over 13 weeks. 0 of 5 covered companies beat the S&P 500 on Mansfield relative strength, while 2 of 5 beat the sector itself.

4-Factor Sector Score

An additive sector-relative research score. The four displayed point contributions always equal the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or stale evidence is absorbed inside the affected factor, never applied as a hidden adjustment.

Growth & earnings · 35%Capital efficiency · 25%Valuation · 20%Relative strength · 20%
Alliance Resource Partners, L.P. has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 51% evidence confidence.
Natural Resource Partners L.P. looks inexpensive relative to peers or its own history, but its earnings trajectory has not yet earned the valuation signal.
How this score is built, and what the marks mean

Missing observations are not scored as bad. Their missing weight lowers confidence and pulls the final score toward neutral. PEG is not shown when the ratio cannot mean anything: the company must be making a profit, its price-to-earnings must be positive, and its three-year earnings growth must fall between 5% and 60%. Dividing a price multiple by a loss, or by growth measured off a tiny base, produces a number that looks precise and tells you nothing. Under relative strength, one mark per week shows the last 12 weeks: a mark is filled where the company led S&P 500 by 5% or more over the 13 weeks ending that week, which is the same test used everywhere on this site. Price stage places the company on the same six-step curve the sector itself is placed on — basing, turning, breaking out, leader, fading, asleep — read from how many weeks running it has led S&P 500 and whether that lead is widening or shrinking. It describes where the PRICE stands, not the earnings trajectory and not a recommendation, and it is left blank for a company whose weekly history is too short or too stale to read.

Price and relative strength

LeaderCore Natural Resources, Inc. · $4,231 million
Gap15.4× versus #2 · NACCO Industries, Inc.
Persistence5/8 recent comparable periods
Coverage3/5 companies · 83 observations

Investor read: Core Natural Resources, Inc. is the scale benchmark; Core Natural Resources, Inc. is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.

This conclusion weakens if: Core Natural Resources, Inc.'s growth falls below Core Natural Resources, Inc.'s for two consecutive comparable reports while 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.

Return On Capital Employed

Alliance Resource Partners, L.P. has the highest ROCE among the 5 Thermal Coal companies compared here, at 7.2%. Natural Resource Partners L.P. is next at 3.8%. The same company also holds the highest ROCE change, at +3.1 percentage points. 5 of 5 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Alliance Resource Partners, L.P. leads ROCE at 7.2%, 3.4 percentage points above Natural Resource Partners L.P.. Alliance Resource Partners, L.P. has the strongest latest improvement at +3.1 percentage points. Read the leader beside the density of its reported history: a sparse high return is a candidate; a repeated high return is evidence of durability.

LeaderAlliance Resource Partners, L.P. · 7.2%
Gap89.5% versus #2 · Natural Resource Partners L.P.
Persistence3/8 recent comparable periods
Coverage5/5 companies · 89 observations

Investor read: Alliance Resource Partners, L.P. sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

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.

Valuation Against Growth & Quality

NACCO Industries, Inc. has the lowest PEG among the 5 Thermal Coal companies compared here, at 0.14×. Alliance Resource Partners, L.P. has the lowest P/E at 11.7×, so level and change sit with different companies. 2 of 5 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: NACCO Industries, Inc. has the lowest comparable PEG at 0.14×, 0% below Natural Resource Partners L.P.. Only 2 of 5 companies have earnings and growth steady enough for the ratio to mean anything, so no broad “cheapest stock” conclusion is defensible unless the current multiple, own-history position and growth durability agree.

LeaderNACCO Industries, Inc. · 0.14×
Gap0% versus #2 · Natural Resource Partners L.P.
Persistence0/8 recent comparable periods
Coverage2/5 companies · 3 observations

Investor read: Treat valuation as permission to investigate, never as a standalone reason to buy.

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 recomputed consistently as the trailing P/E divided by that growth rate — reported earnings, never an expected-earnings multiple. 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.

What can make this comparison misleading?

This Thermal Coal comparison names 5 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. 1 of the 5 ranked sections has fewer than three usable current readings. A high growth rate can still be a low-base artefact.

Keep these limits visible

  • A high growth rate can be a low-base artefact. The page keeps level and change separate for that reason.
  • A high ROCE can be temporary or flattered by a small capital base. Read it beside margin, cash conversion and reinvestment.
  • The 4-Factor Sector Score ranks research priority, not portfolio action. Management quality, catalysts and risks need equally fresh evidence before capital is deployed.
  • An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.
  • Thin comparisons: Valuation have fewer than three usable current readings.

How was this comparison built?

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 2026-08-04. A second data feed fills gaps only after identity and scale reconciliation, and missing observations are never interpolated.

How is the 4-Factor Sector Score calculated?

Which Thermal Coal company earns the highest return on capital?

Alliance Resource Partners, L.P. leads on return on capital employed at 7.2%, across 5 of 5 companies. Read it beside the length of its reported history: a high return that repeats for years is evidence of a durable business, while a single high reading can be a small capital base or one good year.

Which Thermal Coal stock is the cheapest?

On PEG — where a LOWER number is cheaper — NACCO Industries, Inc. screens cheapest at 0.14×. Only 2 of 5 companies have earnings and growth steady enough for the ratio to mean anything, so this is not a sector-wide "cheapest stock" verdict.

Which Thermal Coal stock has the strongest price momentum?

Alliance Resource Partners, L.P. has the strongest relative strength against S&P 500. Relative strength answers last, after growth, quality and valuation: price can move well before the fundamentals confirm it, and sometimes without them confirming at all.

Which Thermal Coal company scores highest for research priority?

This ranks what deserves work next. It is not a buy recommendation, and management quality, catalysts and risk still need separate research.

How many Thermal Coal companies does this comparison cover, and over what period?

It compares 5 listed companies over up to 20 reported quarters of fundamentals, ending Jun 2026, plus weekly price and relative-strength history. Membership is the full sector list — nothing is dropped for having thin data.

The 5 Thermal Coal companies on this page carry $11,767 million of combined market value. Core Natural Resources, Inc. is the largest at $4,090 million, about 35% of the sector's total on its own. Market value moves with price, so this reading is dated 2026-08-04.

What is the Thermal Coal sector's P/E ratio?

The median price-to-earnings ratio across the 5 Thermal Coal companies on this page is 14.2×, measured on the 5 that report a comparable figure. A sector-level history for this multiple is not held here, so this is a cross-section of today, not a comparison with the sector’s own past. Figures are as of 2026-08-04.

How is the Thermal Coal sector performing?

0 of the 5 covered Thermal Coal companies are beating S&P 500 on Mansfield relative strength. The sector itself is 4.2% behind S&P 500 over 52 weeks on an equal-weight index of its current members. Readings are as of 2026-08-04.

Why are some values on this page blank?

A blank means that company did not report a comparable figure for that period, so nothing is shown. Missing observations are never interpolated, carried forward, or replaced with a similar-looking accounting line, and a company with missing evidence has its research score pulled toward neutral rather than being scored as bad.

Is this investment advice?

No. Every figure here is a deterministic calculation from reported company filings and market data, published for research. It contains no recommendation to buy or sell any security, does not account for your circumstances, and is not a substitute for advice from a licensed adviser.
