Beginner’s Guide to Analyzing Coal Mining Stocks

Learn how coal mining companies operate, why they are cyclical, and what factors you should consider before investing in their stocks.

Coal mining stock analysis

Introduction

Coal mining remains one of Indonesia’s most vital industries, fueling power plants and contributing significantly to the national economy. For investors, coal companies can look highly attractive during price surges, but they are also cyclical and come with unique risks. Understanding how these businesses generate revenue and the factors that drive their profits is essential before buying their stocks.

Understanding the Coal Mining Sector

The coal sector falls under the broader energy industry. Within this sector, there are three main sub-industries:

  • Coal Production – mining and extracting coal.
  • Coal Distribution – transporting coal to buyers.
  • Coal Equipment & Services – providing tools, machinery, and consulting for mining operations.

A Simple Analogy

Imagine three characters: a treasure hunter (coal producer), a courier (coal distributor), and a tool seller (equipment provider). Each plays a role in the ecosystem and earns profit in different ways. In this article, we’ll focus on the first one—coal producers.

Coal Companies are Cyclical

Coal mining companies are price takers, not price makers. Unlike consumer goods companies that can set their own selling prices, coal miners must sell at international market prices. This makes their revenue fluctuate based on global demand and supply.

Price Dynamics

Coal prices are quoted in US dollars per ton and can swing dramatically. For example:

  • In 2022–2023, prices reached $400 per ton.
  • Average profitable range: as long as coal stays above $80 per ton, most miners remain profitable.

When prices soar, coal companies enjoy a “party.” But when they drop, thin margins can threaten survival.

How Coal Companies Make Money

The business model is simple on the surface:

  1. Secure mining land.
  2. Strip away soil layers (overburden).
  3. Extract coal and measure output.
  4. Sell at market price per ton.

Profit comes from the difference between the selling price per ton and the average cash cost per ton.

Key Factors Investors Must Watch

1. Average Cash Cost

This includes expenses such as excavation, equipment rental, labor, and transportation. Public companies often disclose this in their public exposés. For instance:

  • Adaro’s cash cost ranged from $27 to $39 per ton (2008–2012, excluding royalties).
  • Bayan Resources had $35–$43 per ton depending on the year.
  • Indo Tambangraya Megah (ITMG) often reported around $40–$50 per ton.

2. Strip Ratio

This refers to how much overburden must be removed to access 1 ton of coal. The lower the ratio, the lower the cost. Example:

  • ITMG: 10.7 tons of soil per 1 ton coal.
  • PTBA: 5.7 tons.
  • Adaro & Bayan: only about 3 tons.

Clearly, companies with lower strip ratios have a cost advantage.

3. Market Demand

Coal demand is tied to electricity generation worldwide. Just like chicken prices rise near festive seasons, coal prices rise when global demand spikes. This makes the sector highly sensitive to global energy trends and government policies on renewables.

Risks and Opportunities

While coal stocks can deliver huge profits during commodity booms, they are vulnerable when prices fall. Investors must calculate whether the selling price comfortably exceeds the company’s average cash cost. Always check disclosures, financial reports, and strip ratios before investing.

“Coal mining is cyclical: when the world needs more power, profits soar. When demand drops, margins shrink fast.”

Conclusion

Coal mining stocks can be rewarding but require a careful, analytical approach. By monitoring average cash cost, strip ratio, and global demand trends, you can identify which companies are better positioned to survive downturns and thrive during upswings.
