MATERIALS SECTOR BREAKDOWN
Now youâve got the basics of how the Materials sector works, an understanding of its history, and its high-level drivers. But a high-level understanding is just the beginning. Just like our overall economy, each sector is made of many distinct partsâsome are relatively similar to others and some are quite unique. To better understand the whole, you must understand the parts.
Chapter 1 covered the basic categories of the Materials sector: metals, chemicals, construction materials, and paper. But thatâs really an oversimplificationâall the metals and chemicals have unique characteristics and drivers. This is also true of the other Materials industries and the sub-industries that comprise them.
Before making any portfolio decision, you must understand what makes each distinct sector component tick. This chapter explores the sectorâs sub-industries and how an investor can form an opinion on each.
GLOBAL INDUSTRY CLASSIFICATION STANDARD (GICS)
Before beginning, some definitions: The Global Industry Classification Standard (GICS) is a widely accepted framework for classifying companies into groups based on similarities. The GICS structure consists of 10 sectors, 24 industry groups, 68 industries, and 154 sub-industries. This structure offers four levels of hierarchy, ranging from the most general sector to the most specialized sub-industry:
⢠Sector
⢠Industry group
⢠Industry
⢠Sub-industry
Letâs start by breaking down Materials into its different components. According to GICS, the Materials sector consists of one industry group (Materials), five industries, and 15 sub-industries. Below are Materialsâ industries and corresponding sub-industries.

GLOBAL MATERIALS BENCHMARKS
Whatâs a benchmark? What does it do, and why is it necessary? A benchmark is your guide for building a stock portfolio. You can use any well-constructed index as a benchmarkâexamples are in Table 4.1.

By studying a benchmarkâs makeup, investors can assign expected risk and return to make underweight and overweight decisions for each industry. This is just as true for a sector as it is for the broader stock market, and there are many potential Materials sector benchmarks to choose from. (Benchmarks will be further explored with the top-down method in Chapter 7.)
Differences in Benchmarks
So what does the Materials investment universe look like? It depends on the benchmark, so choose carefully! The US Materials sector looks very different from Europe, Japan, and the emerging markets. Table 4.1 shows major domestic and international benchmark indexes and the percentage weight of each sector.
Sector weights show each sectorâs relative importance in driving overall index performance. While Materials is the third largest weight in the MSCI Emerging Markets index, itâs the smallest weight of any sector in the US-based S&P 500. Why do Materials have more relative weight in emerging markets? Given a wealth of natural resources, but a lack of infrastructure and discretionary income to support other sectors, emerging markets typically have larger Energy and Materials sector weights than developed countries.
Since the weights are representative of the underlying sector and regionsâ structures, the weights arenât fixed and can change over time because of performance differences, additions and deletions of firms to the indexes, and a variety of other factors. For example, Financials wasnât always the biggest in most indexes. For many decades, Industrials dominated.
Understanding how your benchmark and the sectors within it are structured is crucial to developing a portfolio, since wide deviations in weightings can exist across regions and benchmarks. For example, in some countries, Materials is by far the largest sector; while in others, itâs barely a few percent.
Table 4.2 shows the Materials sectorâs weight in selected countries, based on the MSCI All Country World Index. Note the stark differences between developed and emerging market countries. For example, Peruâs stock market is dominated by
Table 4.2 Materials Weights by Country

| Country | Weight (%) |
|---|
| Peru | 76.6 |
| Brazil | 29.9 |
| Australia | 24.5 |
| South Africa | 21.1 |
| Mexico | 17.2 |
| Canada | 16.8 |
| Germany | 14.9 |
| UK | 10.8 |
| Russia | 10.7 |
| France | 9.1 |
| India | 7.9 |
| China | 6.9 |
| US | 3.5 |
| Spain | 0.6 |
| Italy | 0.4 |
Materialsâmainly mining firmsâbut the big, diverse US market is near the bottom of the list with only a 3.5 percent Materials weight.
Not only can sector weights vary, but so can industry weightsâsometimes greatly, depending on the chosen benchmark. Table 4.3 shows the weight of each Materials industry within each benchmark.
Understanding these weights allows you to not only properly weight your portfolio relative to your benchmark, but also effectively utilize your time by focusing on the most important components. (And for this reason, this book focuses more on the two largest industriesâMetals & Mining and Chemicalsâand less on the smallest industryâContainers & Packaging.)
Metals & Mining is the largest Materials industry in most broad global and non-US benchmarks. Because the industry is concentrated in dominant foreign mining firms, it has a much smaller US weight (Chemicals hold the largest US weight). The Metals & Mining industry also has less impact on small cap indexes (like the Russell 2000) because much of its weight is concentrated in larger firms. This wasnât always the case, but as machines have replaced manual labor and fixed costs have risen as a percentage of total costs, the benefits of economies of scale have grown and so have the firms.

Itâs important to consider regional composition as well. In a top-down context, local economic and political conditions have a large impact on sector, industry, and sub-industry performance. For example, if the US outperforms, that bodes well for the Chemicals, Paper & Forest Products, and Containers & Packaging industriesâall with large US weights relative to the rest of the sector. For a similar reason, if the emerging markets outperform, Metals & Mining and Construction Materials should benefit. Using the MSCI All Country World Index (ACWI), Table 4.4 shows the regional distribution of global Materials industries.
Table 4.5 further breaks down sector sub-industry weights (largest weights by index are bolded). Gold made a lot of headlines in 2007 and 2008, but note it makes up just 0.4 percent of the MSCI World Index and 6.1 percent of the MSCI World Materials sector. Itâs an even smaller weight in most other benchmarks. You could ignore gold altogether and not significantly impact your ability to outperform most Materials benchmarks.

Diversified Metals & Mining has the most impact in global indexes, because it contains firms producing copper, iron ore, and coal, the three largest revenue sources for global mining companies.
Notice how the structure of industries described in Chapter 1 influences the weightings across indexes in Table 4.5. For example, Commodity Chemicals has its greatest weight in Emerging Markets and Specialty Chemicals has its greatest weight in the small cap Russell 2000 Index. Can you guess why? Because commodity chemicals are priced globally and compete fiercely on production costs, producers have migrated to regions with the lowest cost of production. By comparison, specialty chemicals are priced regionally and serve niche markets, so a host of small regional producers exist.
Even Broad Indexes Have Cracks
Stock market indexes only track publicly listed firms in designated countries. No index tracks every firm. Some of the largest holders of natural resources in the world are governments, and others are in very small markets that most indexes do not include. This means some of the worldâs largest mineral producers are not reflected in most, if any, stock market indexes. For example, Codelco, the largest copper producer in the world, is owned by the government of Chile and not included in any indexes. Saudi Basic Industries, the worldâs largest chemical company, is based in Saudi Arabia and included in very few of the broadest global indexes.
A Concentrated Group
When determining your over- and underweights to the benchmark for the Materials sector, itâs important to have an opinion on (or at least knowledge of) the sectorâs largest companies. Recall from Chapter 1 that s...
