Riot Platforms stock jumps 12% as CFO change and data-center incentives come into focus

NEW YORK, Jan 4, 2026, 09:58 ET — Market closed Riot Platforms shares jumped 11.8% on Friday, the last trading day, after a regulatory filing detailed a chief financial officer transition and changes to executive incentives tied to the company’s push into data-center development.

DroneShield stock: JPMorgan trims stake as shares jump 8% — what to watch next

Micron stock jumps 10% on Bernstein target hike as AI-memory bets carry into 2026

NEW YORK, Jan 4, 2026, 09:29 ET — Market closed Micron Technology, Inc. shares ended Friday’s session up 10.5% at $315.42, after Bernstein SocGen Group raised its price target on the memory-chip maker to $330 while keeping an “outperform” rating.

Nvidia stock (NVDA) heads into CES week after Friday rebound as SEC filing flags planned insider sale

NEW YORK, January 4, 2026, 09:31 ET — Market closed Nvidia (NVDA) shares closed up 1.26% at $188.85 on Friday, a firm start to 2026 as chip stocks led a rebound in U.S. equities. The stock traded between $188.26 and $192.93 and saw roughly 148 million shares change hands. The move matters because Nvidia remains a bellwether for risk appetite in semiconductors, and early-January positioning can set the tone for the quarter. With the company’s heavy weight in major indexes, small swings often ripple into the broader AI-linked trade. Investors now face a narrow window of catalysts that can reset

Applied Optoelectronics stock jumps 14% to start 2026 as AI data-center optics rally

NEW YORK, January 4, 2026, 07:17 ET — Market closed Applied Optoelectronics’ shares jumped 13.6% in the last regular session on Friday, closing at $39.60. The stock traded between $35.82 and $40.06 during the session. The outsized move mattered because it came on the first trading day of 2026, when positioning and thinner liquidity can amplify swings in smaller, higher-volatility names. “Value is outperforming growth and AI infrastructure is up,” said Jed Ellerbroek, portfolio manager at Argent Capital, describing Friday’s broader tape. Reuters Applied Optoelectronics’ gain also landed alongside strength in optical and networking peers. Lumentum rose 4.7%, Coherent climbed

Sandisk stock today: SNDK ends last session up nearly 16% after board pick, with traders eyeing Jan. 29 earnings

NEW YORK, January 4, 2026, 06:44 ET — Market closed Sandisk Corp shares closed up 15.95% at $275.24 on Friday, leading U.S.-listed storage and memory names into the first session of 2026. U.S. equity markets are closed on Sunday. The sharp move matters because Sandisk has become a bellwether for investor bets that artificial-intelligence data centers will keep driving demand for storage hardware, after a blockbuster 2025 run for the stock, Barron’s reported. The question now is whether that momentum carries into January as investors reset positioning for the new year. Barron’s Sandisk said it appointed Alexander R. Bradley, chief

NEW YORK, January 4, 2026, 06:28 ET — Market closed. Applied Digital Corporation (APLD) shares jumped 14.6% on Friday to close at $28.11, after trading between $24.65 and $28.44. Trading volume was about 36.1 million shares.

Micron (MU) stock jumps 10% as Bernstein lifts target on AI-driven memory price upcycle

NEW YORK, January 4, 2026, 05:50 ET — Market closed Micron Technology shares surged 10.5% to close at $315.42 on Friday, as a bullish analyst note helped extend a powerful rally in memory stocks tied to artificial-intelligence data centers. The move matters now because memory is one of the key inputs for AI servers, and tighter supply can push up prices quickly. Higher prices typically flow straight into chipmakers’ margins when they sell more of the same bits at better terms. Micron is a major supplier of DRAM (dynamic random access memory, a type of working memory used in computers

NEW YORK, January 4, 2026, 05:32 ET — Market closed D-Wave Quantum Inc shares ended Friday up 7.6% at $28.13, with about 48 million shares traded as the stock ranged between $25.44 and $28.42. The move matters because the quantum-computing sector has started 2026 with renewed momentum, and D-Wave is approaching a busy stretch of investor-facing events. Traders have also been recalibrating their bets on high-growth, high-volatility names after fresh guidance from Federal Reserve officials. Philadelphia Fed President Anna Paulson said on Saturday that further U.S. rate cuts could be some way off as policymakers take stock of inflation and

The Philadelphia Semiconductor Index, a benchmark of major chip stocks, climbed 4% as the Dow rose 0.66% and the S&P 500 gained 0.19%, while the Nasdaq finished slightly lower, Reuters reported.
