10. CoreWeave Inc. (NASDAQ:CRWV)

CoreWeave rallied for a third straight session on Wednesday, jumping 9.40 percent to close at $81.96 apiece, as investors welcomed the launch of new products designed to provide customers with flexibility.

In a statement, the company unveiled Flex Reservations and Spot, which can provide customers with cost-efficient options for interruptible work and more control over how they run AI, as well as enable them to move beyond the binary choice of reserved capacity versus on-demand capacity.

“At production scale, infrastructure planning becomes as critical as deployment. CoreWeave is setting the standard for the AI cloud by providing guaranteed capacity when it counts and flexible pricing when demand shifts,” said Chen Goldberg, CoreWeave Inc.’s (NASDAQ:CRWV) EVP for product and engineering.

“We’re bringing the original promise of the cloud—scale and efficiency—back to the AI pioneers pushing the limits of innovation,” she noted.

Apart from the flexible plans, CoreWeave Inc. (NASDAQ:CRWV) also partnered with PhysicsX to offer the latter’s platform on its high-performance cloud infrastructure. This would enable customers to train their private, domain-specific Large Physics Models (LPMs) on proprietary data, and deploy them within secure enterprise environments.

PhysicsX will also train its pre-trained LPMs on CoreWeave Inc.’s (NASDAQ:CRWV) platform, leveraging scaling laws to build increasingly capable models that can generalize across broader engineering domains and more complex physical systems.

9. The Mosaic Company (NYSE:MOS)

Mosaic bounced back by 10.08 percent on Wednesday to finish at $29.15 apiece, as investor sentiment was boosted by its ongoing efforts to ramp up its rare earth mining exposure with the planned development of a new mining site in Minas Gerais, Brazil.

In a statement, The Mosaic Company (NYSE:MOS) said that its subsidiary, Mosaic Fertilizantes P&K Limitada, along with its partner, Rainbow Rare Earths Ltd., has already completed an economic assessment for the mining site which indicated a potential processing of 2.7 million tons per year of phosphogypsum, 1,900 tons of separated neodymium and praseodymium oxide, and 600 tons of a samarium, europium, and gadolinium product rich in medium and heavy rare earth elements.

The two parties would conduct a pre-feasibility study, and assuming favorable results, they intend to progress to the conduct of a definitive feasibility study.

Construction of the processing facility is targeted next year, with official production by 2030.

“Brazil is emerging as a strategically important jurisdiction for rare earth development in the Americas. The Uberaba project brings together Mosaic’s Brazilian operations with Rainbow’s rare earth expertise,” The Mosaic Company (NYSE:MOS) President and CEO Bruce Bodine.

“Together, we will evaluate the responsible recovery of critical materials from our existing phosphate operations. This initiative aligns with our strategy to unlock additional value from our existing assets,” he noted.

8. Red Cat Holdings Inc. (NASDAQ:RCAT)

Red Cat rallied for a second day on Wednesday, surging 10.16 percent to close at $16.16 apiece, as investors loaded portfolios ahead of the results of its earnings performance for the fourth quarter and full-year period of 2025.

In a notice to its investors, Red Cat Holdings Inc. (NASDAQ:RCAT) said that it would hold an earnings conference after market close on Wednesday, March 18.

In the full year alone, Red Cat Holdings Inc. (NASDAQ:RCAT) is expecting to report revenues of $38 million to $41 million, or growth of 153 percent from the $15.6 million in 2024.

“This outperformance was driven by robust demand from defense and government customers, expanding program wins, and our ability to rapidly scale production to meet mission-critical requirements,” Red Cat Holdings Inc. (NASDAQ:RCAT) CEO Jeff Thompson said earlier.

“As we look ahead into 2026, we see continued growth, supported by an increased pipeline, improving operating leverage, and our expanding role as a trusted provider of next-generation unmanned systems,” he noted.

7. IREN Ltd. (NASDAQ:IREN)

IREN climbed by 10.13 percent on Wednesday to finish at $41.98 apiece, as investor optimism was fueled by Nvidia Corp.’s ramped up investments in data center companies, strengthening its confidence for the artificial intelligence sector.

In an announcement on the same day, Nvidia said that it invested $2 billion in Nebius Group and inked a deal with the latter for the development and deployment of next generation of hyperscale cloud for the AI market, deepening relationship across the full AI technology stack, from AI factory architecture to production software.

Sitting at the center of the rapidly growing AI industry, investors have long been watching Nvidia’s investments as it often signals which companies could become important in the AI boom.

For IREN Ltd. (NASDAQ:IREN), on the other hand, Nvidia’s investment in the industry opens further room for business growth, as it gradually transitions to AI servicing from purely Bitcoin mining.

In other news, IREN Ltd. (NASDAQ:IREN) earlier announced targets of $3.7 billion in annualized run-rate revenues by the end of the year, to be supported by its successful expansion of Nvidia B300 GPU fleet to a total of 150,000 units, with the recent purchase of 50,000 earlier this month.

The additional GPUs are targeted to be deployed in phases across its existing data centers in Mackenzie, British Columbia, and Childress, Texas through the second half of the year.

6. Hims & Hers Health Inc. (NYSE:HIMS)

Hims & Hers extended its winning streak to a third consecutive day on Wednesday, jumping 10.27 percent to close at $25.88 apiece, as investors resumed buying positions after a series of analyst upgrades, thanks to its renewed partnership with Novo Nordisk.

In separate market reports, Deutsche Bank, Citigroup, and Bank of America (BofA) all upgraded their price targets for the stock to $28, $24, and $23, from $25, $13.25, and $12.50, respectively.

Deutsche Bank maintained its “neutral” stance, while Citigroup and BofA upgraded their ratings to “neutral” from “sell” and “underperform,” respectively.

For its part, BofA’s upgrade followed Novo Nordisk’s withdrawal of its earlier lawsuit filed against Hims & Hers Health Inc. (NYSE:HIMS) in relation to its sale and marketing of compounded versions of the former’s blockbuster drugs, Wegovy and Ozempic.

Earlier this week, the two firms announced the renewal of the partnership, with Hims & Hers Health Inc. (NYSE:HIMS) agreeing to the discontinuation of sale and marketing of the compounded drugs.

Hims & Hers Health Inc. (NYSE:HIMS) said that it would only offer access to its own GLP-1 in cases that the needs of the customers cannot be met using the FDA-approved version, and if a provider determines that a compounded product is clinically necessary.

While we acknowledge the potential of HIMS to grow, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and have limited downside risk.
