The metals industry is a subsector of basic materials. It includes companies that:

  • Mine, process, or invest in the extraction of precious metals such as gold, silver, platinum, and palladium.
  • Mine and process industrial metals such as copper, iron ore, and aluminum ore (bauxite).
  • Convert raw metal materials like iron ore into more valuable metal products such as steel.

There’s a blurred line between this sector and mining. Some metals companies operate an integrated mining business, while others don’t. Here’s a closer look at this subgroup of the basic materials sector and some of the best metals stocks to invest in.

Rio Tinto

Rio Tinto (NYSE:RIO) is a diversified global mining company. It primarily focuses on producing industrial metals, including the three most widely used ones -- iron ore, aluminum, and copper.

Rio Tinto is a global leader in producing aluminum. The company operates large-scale, high-quality bauxite mines, alumina refineries, and aluminum smelters. It’s a leader in using low-cost, carbon-free hydroelectricity to power its aluminum operations. Rio Tinto is also a top producer of iron ore, a key ingredient in steel (the most-used metal alloy in the world). The company’s iron ore operations in Australia are composed of an integrated network of world-class mining assets, processing hubs, rail lines, and port terminals that help keep costs low. It complements those leading operations with a large-scale copper business and a meaningful titanium enterprise.

Rio Tinto aims to be a low-cost producer to help mute the impact of metals price volatility. Combined with its diversification, Rio Tinto is a top option for investors seeking broad exposure to the metals sector.

Nucor

Nucor (NYSE:NUE) is a diversified North American steel and steel products company. It makes steel bars, plates, and beams, and it produces steel products such as fasteners, pipes, and wire. Nucor also operates a leading scrap-metal business that recycles and transports ferrous (iron-containing) and nonferrous metals.

Nucor differs from most other steel manufacturers in that it focuses on operating minimills, which use electric arc furnaces to melt scrap steel. This process is less expensive than the traditional blast furnaces used to melt iron. It also powers its facilities primarily with natural gas instead of coal, which costs less. Add to that its focus on using recycled metals, and Nucor is one of the lowest-cost producers of steel in the world.

The company’s relatively environmentally sustainable and lower-cost operations have enabled it to turn a profit in a range of economic conditions. Because of that, it may be an ideal stock for investors seeking a lower-risk steelmaker.

Wheaton Precious Metals

Wheaton Precious Metals (NYSE:WPM) is one of the largest streaming companies in the world. As a streamer, it provides mining companies with an initial payment to help develop a project. In exchange, it receives the right to purchase a portion of the production at a fixed cost.

Wheaton Precious Metals has a diversified portfolio of streaming contracts. Its agreements give it the right to purchase gold, silver, palladium, and cobalt from a variety of leading mining companies. Its streams include currently producing mines, as well as those in development.

The company’s contract portfolio allows it to buy silver and gold at average per-ounce prices of $5.81 and $451, respectively, through 2025. It can then sell those metals at prevailing market prices, pocketing the difference. With gold ending 2021 near $1,800 per ounce and silver above $22, Wheaton made a hefty profit on its precious metal streaming contracts. Wheaton’s low-cost business model makes it an attractive means of investing in precious metals.

The metals industry and the economy

Metals companies largely fall into two categories:

  1. Those focused on precious metals like gold and silver.
  2. Those that produce or use industrial metals such as iron ore, aluminum, and copper.

Consequently, metals companies have different sensitivities to the global economy.

Demand and prices for industrial metals tend to rise and fall with the global economy. A recession typically causes demand and prices to fall, weighing on the profitability and stock prices of companies focused on producing industrial metals. For example, the COVID-19 pandemic-induced recession weighed on industrial metal demand in early 2020, taking prices down with it.

However, the subsequent economic recovery was a boon for industrial metal demand and prices. In addition to economic stimulus, the U.S. Congress passed infrastructure legislation in 2021. This action should drive demand for industrial metals such as steel -- a key metal used to build bridges and other infrastructure -- in the coming years.

The value of precious metals, on the other hand, tends to have an inverse relationship to the economy. That’s due in large part because investors buy these metals to protect their wealth or to hedge against inflation, which is more likely to rise after central banks lower interest rates to counter an economic downturn. Investors saw evidence of this during the pandemic. Economic turmoil and government stimulus sent silver and gold prices to multi-year highs.

Given the inverse relationships between these types of metals, investors might want to consider pairing a company that focuses on industrial metals with one that focuses on precious metals to help smooth out returns.
