When China limited the export of Gallium and Germanium in 2023, markets were reminded that supply chains can be disturbed. These metals may not be well -known names, but they are crucial for semiconductors, defense systems and renewable energy, and therefore the limitations attracted immediate attention from the market.
Investors again turn into the resilience of the supply chain as a portfolio care. Rare earth elements are in the same category as Gallium and Germanium. Embedded in electric vehicles, advanced weapons and infrastructure for clean energy, rare earth elements represent one of the few assivathemas where geopolitics directly drives the market results.
That reality was underlined in July, when the United States supported MP materials, his only active rare earthminder worker, with a package of millions of dollars including equity, loans and a 10-year price base on Neodymium and Praseodymium. The deal, further discussed in Winston MAs Entrepreneurial investor Analysis of a potentially American sovereign asset fund shows how the policy of rhetoric is going to concrete capital obligations.
For investors, the right question is not whether rare earths ‘can beat the market’. It is as if they can offer diversification and resilience in times when traditional portfolios are vulnerable.
A portfolio framing: rare earths as a stress hedge
To evaluate this, I have built a maximum Sharpe ratio portfolio using five ETFs:
- Remx – Rare Earth & Strategic Metals
- Lit – Lithium & Battery Technology
- Ita – Aerospace & Defense
- Gld – Gold (geopolitical hedge)
- IEF – US Treasuries (defensive anchor)
The aim was not to design a market-complaining strategy, but to evaluate or add rare earth blades portfolio spring power. I used monthly returns from January 2018 to July 2025, a 36 -months rolling Covarian Matrix and every three -monthly balance. The results:
- Annual return: 11.45% versus 14.53% (S&P 500)
- Volatility: 21.95% versus 17.19%
- Sharpe ratio: 0.43 versus 0.73
If only on the Sharpe ratio, the portfolio performed over wide shares. But this lacks the real point: rare earths perform the tendency to surpass during geopolitical shocks and disturbances of the supply chain, exactly when traditional portfolios are most at risk.
For investors, the practical collection meals to test rare earths alongside other diversifiers, such as raw materials, infrastructure or defense shares, in a satellite sleeve.
When rare earths shine
Looking at recent episodes of stress and transition, emphasizes how rare earths can function as a hedge when traditional portfolios stumble.
- 2019 United States – China Commercial dispute: During the 2019 rate position, rare Earth and Defense ETFs went on, even when the S&P stumbled. This divergence emphasized their value as a hedge against policy-driven supply chain risks.
- 2020–2021 Ev Adoption Rally: As the demand for electric vehicles accelerated, lithium and rare earthly exposure to the market. For investors this underlines their potential to capture secular growth trends and at the same time add diversification.
- 2023 Export checks: When China limited the export of Gallium and Germanium, rare earth themes attracted renewed attention and surpassed them better. The episode showed how policy shocks can create “thematic alpha” when traditional markets are vulnerable.
These outbursts illustrate the real value: rare earths function as a shock absorber. They will not replace shares, but they can offer a counterewight when macro risks flare.

Practical applications
- Thematic diversification: Use rare earths as a satellite allocation that complements large secular themes: electrification, defense modernization and the transition of clean energy. These exposures can give portfolios targeted access to structural growth trends.
- Geopolitical risk premium: Recognize that policy shocks, not just market cycles, can stimulate returns. Export bans, rates and delivery disruptions often move rare earth markets independent of shares, which gives investors a rare source of real diversification.
- Portfolio construction: Test rare earths as a sleeve of 5% to 10% within a diversified portfolio. Combine them with gold and treasure chest to balance risks. The goal is not to perform better than shares, but to add resilience when shares are emphasized.
Important collection restaurants
- Rare earths are not a silver bullet, but they are a geopolitical hedge that cannot ignore investors.
- Traditional risk traps (Sharpe Ratio) underestimate their value: non-correlation and tail events.
- For allocators, the right framing is resilience, not haunting again.
- In a world where supply chains are vulnerable, rare earths are more than a raw material story. They are a portfolio strategy for managing geopolitics risk.
