Alphabet stock posts best weekly performance on robust earnings and cloud revenue
Alphabet shares surged 6%

​Alphabet Inc. [GOOGL] stock price advanced on Friday, carrying forward Thursday’s momentum after a powerful earnings-inspired rally that reaffirmed investor confidence in the tech giant’s growth outlook. In the premarket session, GOOGL traded near $284.6, up 1.35% from the prior close at $281.1, as traders reacted to Alphabet’s record-setting quarterly results.

- Alphabet shares surged 6% Thursday, posting a record $291.5 before trimming late gains.

- Cloud revenue jumped 34% to $15.2 billion, strengthening Alphabet’s AI-driven momentum.

- Alphabet’s 12% weekly rally marks the strongest performance this year.

On Thursday, the stock surged 6% to a new all-time high of $291.5 before trimming gains to close slightly lower. The rise came shortly after the Federal Reserve’s quarter-point rate cut and Alphabet’s blockbuster third-quarter earnings report, both of which fuelled optimism across the technology sector. Alphabet’s performance exceeded Wall Street expectations, delivering stronger-than-forecast results across revenue, earnings, and cloud growth.

For the quarter ended September 30, Alphabet reported total revenue of $102.4 billion, surpassing analyst projections and exceeding the $88.3 billion recorded in the same period last year. Profitability improved sharply as adjusted earnings per share climbed to $2.87, higher than both last year’s figures and consensus estimates. Investors were particularly impressed by Alphabet’s cloud division, which saw a 34% increase in revenue to $15.2 billion. The company’s cloud backlog expanded to $155 billion, reflecting strong corporate spending on data infrastructure and AI-related applications.

Alphabet overbought RSI hints at cooling pace after 12% weekly gain

These numbers reinforced the strength of Alphabet’s position in the broader artificial intelligence and cloud computing landscape. The upbeat results helped lift GOOGL’s weekly gain to nearly 12%, marking its best weekly performance this year. For October, Alphabet is closing out the month up more than 17%, setting up its seventh straight monthly advance and its largest monthly gain in a decade.

As trading heads into the final hours of October, GOOGL’s rally shows limited signs of exhaustion, though near-term indicators point to possible moderation. Both the daily and hourly RSI readings have climbed into overbought territory, suggesting the pace of gains may slow before buyers reassert control. Despite this technical restraint, market optimism tied to Alphabet’s expanding AI footprint, strong financial base, and steady support from rate-sensitive sectors could keep the stock anchored near record levels going into November.
