Alphabet rises 1.0% as company finalizes large clean-energy deal and rolls out Gemini 4 Argon

What happened

Alphabet (GOOG) rose 1.0% on October 5, 2026, after reports the company was finalizing a multi-year pact to add 890 MW of nuclear capacity, and it unveiled Gemini 4 Argon. Reuters and Business Wire reported Google was finalizing a power purchase agreement with Constellation Energy to bring 890 MW of new nuclear capacity to the PJM grid, a deal Bloomberg said could be worth $1 billion or more. Proactive Investors reported Google unveiled Gemini 4 Argon, described as its most advanced AI model aimed at handling long, multi-step professional tasks.

How big was the move

The stock closed at $343.83, having risen 1.0% on the day and having rose 1.4% over the last five sessions. Trading volume was 0.7 times its 20-day average, and the size of the move measured 0.5 times a typical daily move for this stock, indicating an ordinary session. The S&P 500 rose 0.7% on the day and rose 1.2% over five sessions; the Communication Services sector median rose 0.7%, making Alphabet 0.4 percentage points better than the sector median.

The stock opened 0.3% below the previous close, and its beta was 1.18, meaning the stock tended to move more than the market. Those factors, together with the below-average trading volume and muted intraday range, underlined that the market regarded the developments as incremental rather than catalytic.

The technical picture

The stock was 1.2% above its 20-day moving average and 0.5% above its 50-day moving average, while it sat 1.9% above its 200-day moving average. The 50-day average was above the 200-day average, a sign of an established uptrend, and the Relative Strength Index (14 days) stood at 53, within a neutral range between 30 and 70. The shares were 15.0% below the 52-week high.

Performance over standard horizons was mixed: over one month the stock rose 1.4%, over three months it fell 5.4%, and over one year it rose 39.5%, which was 23.8 percentage points ahead of the S&P 500. Volatility was 34% annualized over 60 days, higher than 66% of its own readings over five years, underlining that price swings have been larger than the company’s recent history more often than not.

Fundamentals and valuation

For the four quarters through June 30, 2026, revenue was $445.87 billion, which grew 20.1% from a year earlier, and diluted earnings per share were $19.91, which rose 112.0% from a year earlier. Gross margin was 60.9% versus 58.9% a year earlier, and operating margin was 33.1% versus 32.7% a year earlier. Free-cash-flow margin was 11.9% and return on invested capital was 15.2%.

The balance sheet showed net debt of 0.2 times EBITDA, and share count over one year increased by 0.9%. On valuation, the stock traded at 17.3 times trailing earnings and 16.7 times expected forward earnings, with a price to trailing earnings lower than 95% of its own readings over the past five years; the five-year median was 24.3 times earnings. Free-cash-flow yield was 1.3% and market value was $4.13 trillion. Those metrics highlight a contrast: strong growth and profitability paired with a valuation that sits well below its recent medians.

Alphabet’s next report was scheduled for October 28, 2026. The last report, on July 22, 2026, delivered earnings per share of $9.11 against $2.87 expected, 217.4% above estimates.
