Stock futures inched higher Friday premarket, rebounding from Wall Street’s prior sell-off as investors assessed Amazon’s mixed earnings results.
Here are some of Friday’s biggest stock movers:
Biggest stock gainers
- Roblox (RBLX) +14% – Shares jumped after Q4 engagement and bookings surged, easing concerns that tighter child safety measures would hurt platform activity. Daily average users rose 69% Y/Y to 144M, hours engaged jumped 88%, and bookings climbed 63% to $2.2B, topping expectations, while revenue rose 43% to $1.4B, slightly below estimates. Loss per share narrowed more than expected despite higher Trust & Safety costs, and upbeat guidance added to the rally, with Q1 sales forecast above consensus and full-year sales seen at $8.28B–$8.55B vs. $8.06B expected.
- Envista (NVST) +13% – Shares advanced after Q4 results beat expectations, with non-GAAP EPS of $0.38 topping estimates by $0.06 and revenue jumping 15% Y/Y to $751M, beating by $71M. For 2026, the company guided to core sales growth of 2%–4%, adjusted EBITDA growth of 7%–13%, and adjusted EPS of $1.35–$1.45, ahead of the $1.28 consensus, while free cash conversion is expected to be around 100%.
Biggest stock losers
- Doximity (DOCS) -33% – Shares plunged despite an upbeat FQ3 results, as weak forward guidance overshadowed the quarter. The company guided Q4 revenue to $143M–$144M, well below the $150.5M consensus, and FY2026 revenue to $642.5M–$643.5M versus $645.4M expected. The outlook miss raised concerns about growth momentum, even as Doximity announced a $500M share buyback authorization, which failed to offset investor disappointment on guidance.
- Stellantis (STLA) -23% – Shares plunged after the automaker said it would sell its 49% stake in the battery joint venture NextStar Energy to partner LG Energy Solution for a nominal $100, marking a sharp reset of its EV strategy. The move hands full control of Canada’s first large-scale battery plant in Windsor, Ontario, to LG Energy, while Stellantis will continue sourcing batteries from the facility. More than C$5B has already been invested in the plant, which employs over 1,300 people and is targeting 2,500 at full scale.
- Amazon.com (AMZN) -8% – Shares slid after the company reported mixed Q4 results, with investor focus squarely on weaker cash flow and heavy spending plans. Free cash flow fell to $11.2B over the trailing twelve months, down sharply as purchases of property and equipment surged $50.7B Y/Y, largely tied to aggressive investments in AI infrastructure. While CEO Andy Jassy emphasized strong long-term opportunities across AI, chips, robotics, and low-earth-orbit satellites, he said Amazon expects to invest roughly $200B in capital expenditures in 2026. For Q1, Amazon guided revenue of $173.5B–$178.5B (midpoint $176.5B), slightly above consensus of $175.5B, but operating income of $16.5B–$21.5B (midpoint $19.0B) fell well short of the $22.2B estimate, reinforcing concerns that elevated capex will pressure margins and cash generation in the near term.
