Stocks making the biggest moves after hours: Apple, Amazon, Coinbase, Netflix and more

Major tech players like Apple and Amazon led after-hours gains, with Apple jumping 4% on strong iPhone 17 demand and Amazon surging 14% driven by robust cloud growth, both exceeding earnings and revenue forecasts. Cloudflare, Twilio, Atlassian, and Coinbase also saw shares rise after beating estimates, while Netflix gained 3% following a 10-for-1 stock split. However, Roku fell 7% due to advertising spending concerns, and both Gilead Sciences and Monolithic Power Systems experienced slight declines despite surpassing their respective top and bottom-line expectations, highlighting selective market responses to earnings reports.

Analysis

The latest earnings reports indicate a robust performance across several major technology and software companies, with Apple and Amazon leading after-hours gains. Apple jumped 4% on fiscal-fourth quarter earnings of $1.85 per share and revenue of $102.47 billion, both exceeding analyst expectations, and provided a strong December quarter forecast driven by iPhone 17 demand. Amazon surged 14% after reporting $1.95 per share and $180.17 billion in revenue, significantly topping estimates, primarily fueled by strong growth in its cloud-computing unit.

Cloudflare, Twilio, Atlassian, Coinbase, Reddit, Zillow Group, and First Solar also demonstrated strong financial performance, beating analyst estimates for both earnings and revenue. Cloudflare shares rose over 8% and Twilio soared 10% on their respective beats, while First Solar gained nearly 4% and raised its 2025 forecast, signaling positive future outlooks. Netflix saw a 3% increase following its announcement of a 10-for-1 stock split, a move aimed at enhancing retail investor accessibility.

Conversely, Roku shares fell over 7% despite beating EPS estimates, attributed to a decline in advertising spending and increased competition, overshadowing its raised full-year platform revenue estimate. Gilead Sciences and Monolithic Power Systems also experienced declines of 1% and 3% respectively, despite beating both top and bottom-line expectations, suggesting market focus on other underlying concerns or segment performance beyond headline figures.

Key Decisions for Investors

• Investors should prioritize companies demonstrating strong fundamental beats and positive forward guidance, particularly in cloud computing and specific tech segments, as evidenced by Apple and Amazon's performance.
• Exercise caution with companies experiencing sector-specific headwinds like declining advertising spend, even if headline earnings appear strong, as seen with Roku.
• Monitor the impact of corporate actions such as stock splits on market accessibility and liquidity, and assess underlying business drivers beyond headline beats for companies like Gilead and Monolithic Power Systems.
