Stock futures inched lower in the premarket hours of Friday after yesterday’s market slide, positioning ahead of critical CPI data.
Here are some of Friday’s biggest stock movers:
Biggest stock gainers
- Corsair Gaming (CRSR) +22% – Shares jumped after posting a solid Q4 beat, with non-GAAP EPS of $0.43 topping estimates by $0.16 and revenue rising 5.6% Y/Y to $436.9M, also ahead of expectations. While FY2026 revenue guidance came in below consensus ($1.33B–$1.47B vs. $1.58B), EPS guidance was broadly in line to higher, supported by expected double-digit growth in Gamer and Creator Peripherals, partially offset by a cautious outlook for Gaming Components amid global semiconductor constraints. Sentiment was further boosted by Corsair’s first-ever $50M share repurchase authorization.
- Rivian Automotive (RIVN) +18% – Shares surged after reporting Q4 results and outlining its 2026 outlook, with investors looking past weaker automotive revenue, down 45% Y/Y due to lower regulatory credit sales, softer deliveries after tax credit expirations, and a lower ASP mix, and focusing instead on strong momentum in software and services, where revenue jumped 109% on contributions from its Volkswagen joint venture and higher service-related sales. While Q4 deliveries of 9,745 slightly missed consensus, Rivian said results were in line with internal expectations and guided to a meaningful pickup in 2026 deliveries of 62K–67K vehicles, alongside adjusted EBITDA of -$2.1B to -$1.8B and capex of about $2B.
- Applied Materials (AMAT) +13% – Shares advanced after delivering FQ1 results and guidance that beat expectations, driven by accelerating AI-related chip investments. Management highlighted strong demand for leading-edge logic, high-bandwidth memory, and advanced packaging, areas where Applied is a market leader, and guided for FQ2 revenue of $7.15B–$8.15B and adjusted EPS of $2.44–$2.84, both comfortably ahead of Wall Street estimates.
- Roku (ROKU) +13% – Shares rose after crushing Q4 earnings estimates and issuing upbeat 2026 guidance. The streaming platform provider reported Q4 adjusted EPS of $0.53, nearly double the expectations, on revenue of $1.38B (+16% Y/Y), which came in line. Strength was driven by platform revenue growth of 18% Y/Y, while management guided Q1 2026 revenue of $1.2B and full-year 2026 revenue of $5.5B, both ahead of consensus.
Biggest stock losers
- Pinterest (PINS) -19% – Shares plunged after reporting weaker-than-expected Q4 results and issuing a soft Q1 2026 outlook. The company guided revenue in the range of $951M–$971M, missing the $981M consensus, implying 11%–14% Y/Y growth that includes a ~3-point FX tailwind. The company also forecast Q1 adjusted EBITDA of $166M–$186M.
- DraftKings (DKNG) -15% – Shares sank after reporting mixed Q4 results and issuing FY2026 guidance that fell short of expectations. Q4 revenue rose 43.2% Y/Y to $1.99B, supported by strong customer engagement, efficient new customer acquisition, and higher sportsbook net revenue margins. Monthly unique paying customers were flat Y/Y at 4.8M, while average revenue per MUP jumped 43% to $143, driven by improved margins across both sportsbook and iGaming. DraftKings guided FY2026 revenue to $6.5B–$6.9B (midpoint $6.7B), well below the $7.3B consensus, overshadowing the solid quarterly performance.
