When China restricted exports of gallium and germanium in 2023, markets have been reminded that provide chains could be disrupted. These metals might not be family names, however they’re essential to semiconductors, protection methods, and renewable vitality, which is why the restrictions drew fast market consideration.
Traders are once more turning to provide chain resilience as a portfolio concern. Uncommon earth parts sit in the identical class as gallium and germanium. Embedded in electrical automobiles, superior weaponry, and clear vitality infrastructure, uncommon earth parts signify one of many few asset themes the place geopolitics straight drives market outcomes.
That actuality was underscored in July, when the USA backed MP Supplies, its solely energetic uncommon earth miner, with a multibillion-dollar bundle together with fairness, loans, and a 10-year worth flooring on neodymium and praseodymium. The deal, mentioned additional in Winston Ma’s Enterprising Investor evaluation of a possible US sovereign wealth fund, exhibits how coverage is transferring from rhetoric to concrete capital commitments.
For buyers, the suitable query isn’t whether or not uncommon earths can “beat the market.” It’s whether or not they can present diversification and resilience in moments when conventional portfolios are weak.
A Portfolio Framing: Uncommon Earths as a Stress Hedge
To judge this, I constructed a Most Sharpe Ratio portfolio utilizing 5 ETFs:
REMX – Uncommon Earth & Strategic Metals
LIT – Lithium & Battery Expertise
ITA – Aerospace & Protection
GLD – Gold (geopolitical hedge)
IEF – U.S. Treasuries (defensive anchor)
The aim was to not design a market-beating technique, however to judge whether or not uncommon earth exposures add portfolio resilience. I used month-to-month returns from January 2018 to July 2025, a 36‑month rolling covariance matrix, and quarterly rebalancing. The outcomes:
Annualized Return: 11.45% vs. 14.53% (S&P 500)
Volatility: 21.95% vs. 17.19%
Sharpe Ratio: 0.43 vs. 0.73
If judged solely on Sharpe ratio, the portfolio underperformed broad equities. However this misses the actual level: uncommon earths are inclined to outperform throughout geopolitical shocks and provide chain disruptions, exactly when conventional portfolios are most in danger.
For buyers, the sensible takeaway is to check uncommon earths alongside different diversifiers, equivalent to commodities, infrastructure, or protection equities, in a satellite tv for pc sleeve.
When Uncommon Earths Shine
Taking a look at latest episodes of stress and transition highlights how uncommon earths can perform as a hedge when conventional portfolios stumble.
2019 United States–China Commerce Dispute: Throughout the 2019 tariff standoff, uncommon earth and protection ETFs superior even because the S&P stumbled. This divergence highlighted their worth as a hedge towards policy-driven provide chain dangers.
2020–2021 EV Adoption Rally: As electrical automobile demand accelerated, lithium and uncommon earth exposures surged forward of the market. For buyers, this underscores their potential to seize secular progress developments whereas including diversification.
2023 Export Controls: When China restricted exports of gallium and germanium, uncommon earth themes drew renewed consideration and outperformed. The episode confirmed how coverage shocks can create “thematic alpha” exactly when conventional markets are weak.
These bursts illustrate the actual worth: uncommon earths perform as a shock absorber. They gained’t exchange equities, however they will present a counterweight when macro dangers flare.

Sensible Functions
Thematic Diversification: Use uncommon earths as a satellite tv for pc allocation that enhances large secular themes: electrification, protection modernization, and the clear vitality transition. These exposures can provide portfolios focused entry to structural progress developments.
Geopolitical Threat Premium: Acknowledge that coverage shocks, not simply market cycles, can drive returns. Export bans, tariffs, and provide disruptions usually transfer uncommon earth markets independently of equities, giving buyers a uncommon supply of true diversification.
Portfolio Development: Check uncommon earths as a 5% to 10% sleeve inside a diversified portfolio. Pair them with gold and Treasuries to steadiness threat. The aim isn’t to outperform equities, however so as to add resilience when equities are confused.
Key Takeaways
Uncommon earths usually are not a silver bullet, however they’re a geopolitical hedge that buyers can’t ignore.
Conventional threat metrics (Sharpe ratio) understate their worth: non-correlation and tail occasions.
For allocators, the suitable framing is resilience, not return chasing.
In a world the place provide chains are weak, uncommon earths are greater than a commodity story. They’re a portfolio technique for managing geopolitical threat.
