Stock futures inched higher Tuesday morning as investors positioned themselves ahead of the next batch of corporate earnings reports.
Here are some of Tuesday’s biggest stock movers:
Biggest stock gainers
- Teradyne (TER) +22% – Shares surged after delivering a strong Q4, with revenue up over 43% Y/Y and upbeat Q1 guidance. The company forecast Q1 revenue of $1.15B–$1.25B, well above the $966.6M consensus, and adjusted EPS of $1.89–$2.25 versus $1.28 expected. Management highlighted broad-based sequential growth across Semi Test, Product Test, and Robotics, with 2026 momentum driven by AI-related compute demand.
- DaVita (DVA) +13% – Shares jumped after beating Q4 revenue and EPS expectations and issuing strong 2026 guidance. The company forecast non-GAAP EPS of $13.60–$15.00, well above the $12.74 consensus, with adjusted operating income of $2.09B–$2.24B and free cash flow of $1.0B–$1.25B.
- TeraWulf (WULF) +12% – Shares advanced after announcing the acquisition of two brownfield infrastructure sites in Kentucky and Maryland, adding roughly 1.5 GW of capacity to its portfolio. The Kentucky site offers immediate access to high-voltage power infrastructure, while the Maryland acquisition includes an operating power plant with 210 MW capacity and expansion potential up to 1 GW. The deals strengthen TeraWulf’s strategy of securing energy-advantaged assets with near-term power availability and long-term scalability.
- Palantir Technologies (PLTR) +7% – Shares rose after Q4 results and guidance beat expectations. Q1 FY2026 revenue is guided at $1.532B–$1.536B, well above the consensus of $1.33B, with adjusted operating profit of $870M–$874M. Full-year revenue is seen at $7.182B–$7.198B, topping estimates, driven by at least $3.144B in U.S. commercial revenue, up over 115% Y/Y. Adjusted operating profit is forecast to be between $4.126B and $4.142B for the year, while adjusted free cash flow is expected to be between $3.925B and $4.125B.
Biggest stock losers
- Rambus (RMBS) -16% – Shares plunged after Q4 results flagged a near-term supply chain disruption that will pressure Q1 FY26 product revenue and EPS. Management cited ongoing memory-related supply constraints limiting its ability to meet demand, prompting Q1 guidance below the prior outlook. While the issue is described as one-time and expected to be resolved with partners, the market focused on the timing hit. CEO Luc Seraphin reiterated confidence in a return to strong growth in Q2, supported by market share gains and new product ramps, and maintained a constructive long-term outlook for 2026 and beyond.
- NXP Semiconductors (NXPI) -5% – Shares slipped despite a strong Q4 finish, as the market weighed robust beats in Mobile and Industrial IoT against slightly soft growth in its core Automotive segment. The company delivered a bullish Q1 2026 forecast with revenue projected at $3.15B, outpacing the $3.09B consensus. NXP also completed the sale of its MEMS sensors business to STMicroelectronics, adding about $45M to STM’s Q1 2026 revenue.
