Stock futures saw modest gains early Friday, on the last trading day of October, driven by investor enthusiasm over generally positive earnings reports from big tech companies.
Here are some of Friday’s biggest stock movers:
Biggest stock gainers
- Amazon (AMZN) +13% – Shares advanced after delivering a strong Q3 beat, with EPS of $1.95 topping estimates by $0.37 and revenue rising 13% Y/Y to $180.2B, driven by solid growth across online and physical stores, third-party seller services, subscription revenue, and a standout 20% Y/Y increase in AWS sales to $33.01B; ad services also exceeded expectations at $17.7B. While operating income of $17.42B and a 9.7% operating margin missed forecasts due to heavier spending, management emphasized an aggressive ramp-up in AWS and AI capacity, noting AWS power capacity has doubled since 2022 and is set to double again by 2027, with full-year cash CapEx expected to be ~$125B in 2025 and rising further in 2026.
- Western Digital (WDC) +10% – Shares jumped after the storage company posted strong FQ1 results with revenue up 27% Y/Y and issued guidance well ahead of expectations, driven by ongoing demand for AI-related storage solutions. For FQ2, WDC expects adjusted EPS of ~$1.88 plus or minus $0.15 (vs. $1.74 est.) and revenue of $2.8B–$3.0B (midpoint $2.9B vs. $2.83B est.), with gross margins projected at 44%–45%. The company also raised its quarterly dividend by 25% to $0.125 per share, payable Dec. 18.
- Twilio (TWLO) +7% – Shares popped after reporting Q3 results and guidance that exceeded expectations. The company repurchased $349.8M of stock in the quarter as part of its $2B buyback program, with ~$1.3B remaining. For Q4, Twilio guided adjusted EPS to $1.17–$1.22 (vs. $1.14 est.) and revenue to $1.31B–$1.32B (vs. $1.28B est.), implying ~9.5%–10.5% Y/Y growth. It also raised its full-year outlook, now expecting FY2025 revenue growth of 12.4%–12.6% (previously 10%–11%) and higher free cash flow of $920M–$930M. However, adjusted operating income guidance was lowered to $400M–$410M (from $850M–$875M), suggesting continued reinvestment and margin pressures.
- Coinbase (COIN) +6% – Shares gained after the firm reported Q3 results that topped expectations, driven by a rebound in trading volumes and lower sequential expenses. The company also guided Q4 subscription and services revenue to $710M–$790M (midpoint ~$750M vs. ~$767M est.), expects transaction expenses to run in the mid-teens as a percentage of net revenue, and projects tech & development plus G&A expenses of $925M–$975M (midpoint ~$950M).
- Apple (AAPL) +3% – Shares soared after delivering better-than-expected FQ4 results, even though iPhone revenue ($49.0B vs. $50.3B est.) and Greater China sales ($14.5B vs. $16.4B est.) came in light. CEO Tim Cook said FQ1 revenue is expected to increase 10%–12%, translating to $136.7B to $139.2B, above the $131.82B consensus, with iPhone returning to double-digit growth and China expected to rebound. He also reiterated that Apple will roll out its AI-enhanced Siri next year, with broader AI integration to follow.
Biggest stock losers
- Roku (ROKU) -6% – Shares plunged after the company reported a mixed Q3 and issued guidance that only slightly topped expectations. For Q4, the company forecast revenue of ~$1.35B and gross profit of ~$575M, both just above consensus, while adjusted EBITDA guidance of ~$395M also came in modestly higher.
