An industry that refuses to be walled in

Amid a decline in wallboard capacity and a shortage of synthetic gypsum, Fidelity Portfolio Manager Jennifer Fo Cardillo believes that the leading manufacturers and distributors of this essential construction material are positioned to benefit from a favorable pricing environment.

“I am enthusiastic about companies leveraged to the production of wallboard due to the constrained supply of gypsum, a key raw material input,” says Fo Cardillo, who co-manages Fidelity® Stock Selector Small Cap Fund (FDSCX), alongside Shadman Riaz, Patrick Venanzi and Eirene Kontopoulos.

In helming the core U.S. small-cap equity strategy, the managers emphasize higher-quality companies with an established and durable competitive moat that can compound and help the firm become a larger, more-profitable business over time.

Fo Cardillo says she focuses on investment themes that are not fully appreciated by the broader market, including firms that stand to benefit from supply-constrained markets and improved industry structures.

Gypsum is a key input for wallboard production, she explains, yet no real substitute for the material exists. About half of the current wallboard supply comes from synthetic gypsum, with the other half coming from its natural counterpart, she adds.

Yet, as existing coal plants are retired, the supply of synthetic gypsum—a byproduct of coal production—is expected to decline, according to Fo Cardillo. This dynamic has been pushing up both costs and prices for wallboard.

For example, she notes that importing or transporting natural gypsum adds between $30 and $100 per ton to the cost of wallboard, compared with a current per-ton industry profit of $40 to $60.

“What’s more, the industry has consolidated, leaving only four main players, which together control 85% of the wallboard market,” she says. “I believe these dynamics should support a favorable pricing environment and provide a tailwind to certain stocks within the portfolio.”

Among them is building-products distributor GMS (GMS), which derives as much as 45% of its profit from wallboard production, according to Fo Cardillo.

Another notable position (as of September 30) is wallboard manufacturer Eagle Materials (EXP), which she sees as a potential outsized beneficiary of current trends due to the company’s standing as a low-cost provider.

Fo Cardillo also notes that about three-quarters of Eagle’s capacity is tied to natural gypsum reserves owned by the company, while the remaining 25% is secured through a long-term agreement that guarantees supply to Eagle.

“Shares of GMS and Eagle are trading at what we believe are reasonable valuations based on near-term earnings that remain below the midpoint of the typical business cycle,” she concludes.

Before investing, consider the funds' investment objectives, risks, charges, and expenses. Contact Fidelity for a prospectus or, if available, a summary prospectus containing this information. Read it carefully.

Because of their narrow focus, sector investments tend to be more volatile than investments that diversify across many sectors and companies.

Growth stocks can perform differently from the market as a whole and other types of stocks, and can be more volatile than other types of stocks.

Value stocks can perform differently from other types of stocks, and can continue to be undervalued by the market for long periods of time.

Stock markets are volatile and can fluctuate significantly in response to company, industry, political, regulatory, market, or economic developments. Investing in stock involves risks, including the loss of principal.

Foreign investments involve greater risks than U.S. investments, including political and economic risks and the risk of currency fluctuations, all of which may be magnified in emerging markets.

In general, the bond market is volatile, and fixed income securities carry interest rate risk. (As interest rates rise, bond prices usually fall, and vice versa. This effect is usually more pronounced for longer-term securities.) Fixed income securities also carry inflation risk, liquidity risk, call risk, and credit and default risks for both issuers and counterparties. Unlike individual bonds, most bond funds do not have a maturity date, so holding them until maturity to avoid losses caused by price volatility is not possible.

The municipal market can be affected by adverse tax, legislative, or political changes, and by the financial condition of the issuers of municipal securities.

The securities of smaller, less well known companies can be more volatile than those of larger companies.

Some funds may use investment strategies involving derivatives and other transactions that may have a leveraging effect on the fund. Leverage can increase market exposure and magnify investment risk. Investors should be aware that there is no assurance that a fund's use of such strategies will succeed.

Leverage can magnify the impact of adverse issuer, political, regulatory, market, or economic developments on a company. In the event of bankruptcy, a company's creditors take precedence over its stockholders.

Changes in real estate values or economic conditions can have a positive or negative effect on issuers in the real estate industry.
