10. Bitdeer Technologies Group (NASDAQ:BTDR)

Shares of Bitdeer Technologies jumped by 10.28 percent on Friday to close at $19.42 apiece, as investor sentiment was influenced by the rally in Bitcoin prices and an overall market optimism for more rate cuts.

As of writing, the price of Bitcoin was at $122,375, marking an increase of 9 percent from a week earlier and 1.62 percent from the previous day.

Over the next few days, investors of Bitdeer Technologies Group (NASDAQ:BTDR) will expect the announcement of its September production results.

Moreover, its increased hashrate fulfills the requirements for large-scale mining operations, offering strong support in computational capabilities,” Bitdeer Technologies Group (NASDAQ:BTDR) said.

9. QuantumScape Corporation (NYSE:QS)

QuantumScape propelled to a new 52-week high on Friday, as investors poured funds into shares of battery companies following the US government’s ongoing initiatives to prop up the lithium industry in the country.

During the session, the stock climbed to its highest price of $16.49 before trimming gains to finish the day just up by 11.33 percent at $15.92 apiece.

Earlier this week, the US government announced plans to acquire a 5 percent stake in Lithium Americas and another 5 percent in its Thacker Pass mine in Nevada, in a bid to boost the domestic supply of lithium and reduce the country’s reliance on imports.

QuantumScape Corporation (NYSE:QS)—a company heavily reliant on lithium to produce batteries for electric vehicles—is set to indirectly benefit from the investment as switching to domestic supplies could significantly lower the costs of raw materials and reduce supply chain disruptions, especially given that China,—the largest lithium producer in the world—remains locked in a trade conflict with the US.

In other news, QuantumScape Corporation (NYSE:QS) recently announced a partnership with Corning Inc. for the joint development of ceramic separator manufacturing capabilities for QS solid-state batteries. The partnership targets to ramp up production of its ceramic separators for commercial applications.

8. D-Wave Quantum Inc. (NYSE:QBTS)

D-Wave Quantum soared to another all-time high on Friday, as investors snapped up shares following news that police operations have improved from using one of its hybrid systems, solidifying the increasing real-world significance of quantum computing technologies.

In intra-day trading, D-Wave Quantum Inc. (NYSE:QBTS) jumped to as high as $33.28 before trimming gains to finish the day just up by 11.95 percent at $32.70 apiece.

This followed news on Thursday that its quantum computing technology helped improve the North Wales Police’s incident response capabilities by 50 percent after the latter leveraged its hybrid-quantum application to optimize the placement of police vehicles for emergency response.

D-Wave Quantum Inc. (NYSE:QBTS) said the partnership resulted in a faster, more accurate, and efficient solution than classical methods alone.

“As police forces increasingly rely on data-driven strategies to improve response times and coverage, hybrid-quantum computing can offer the speed, precision, and intelligence needed to identify optimal officer placements and enhance public safety,” said D-Wave Quantum Inc. (NYSE:QBTS) CEO Alan Baratz.

“Hybrid-quantum computing is beginning to show real-world potential across private and public sectors, and we’re thrilled to see the potential for it to make a meaningful impact in forward deployment with North Wales Police,” he noted.

7. Oscar Health Inc. (NYSE:OSCR)

Oscar Health extended its rally to a second day on Friday to come close to its 52-week high, as investors cheered President Donald Trump’s decision to pause the imposition of a 100 percent tariff on pharmaceutical imports.

Earlier this week, Trump decided to delay the levies on pharmaceutical imports as the government continues to engage in talks with giant drugmakers to lower their prescription drug prices to Americans and make them in line with other developed countries. The decision offered a significant relief to Oscar Health Inc. (NYSE:OSCR) and its insurance counterparts, as it would spare them from immediately raising their premiums and absorbing hefty drug costs as a result of the tariff.

Additionally, pharmaceutical companies’ commitments to the US government to invest in manufacturing facilities in the country would ease pricing pressures over time and help Oscar Health Inc. (NYSE:OSCR) keep its insurance plans affordable to customers.
