Alphabet C (GOOG) Surges 3.7%: What’s Fueling the Rally?

Summary
• Berkshire Hathaway’s $4.3B stake in Alphabet revealed in Q3 13F filing
• Google launches Gemini 3 AI model, embedded in Search and Cloud
• Waymo expands driverless robotaxi operations to four new U.S. cities
• CEO Sundar Pichai warns of AI investment risks, yet stock hits YTD high

Alphabet Class C (GOOG) is surging 3.73% intraday, trading at $300.81 with a range of $294.36–$303.96. The rally follows Berkshire Hathaway’s landmark tech investment, Gemini 3’s commercial rollout, and Waymo’s expansion. Analysts are debating whether the AI-driven optimism is sustainable or a short-term bounce.

Berkshire’s Stake and AI Momentum Drive GOOG’s Rally
The 3.73% surge in Alphabet C (GOOG) is fueled by two major catalysts: Berkshire Hathaway’s $4.3 billion stake in Alphabet, revealed in its Q3 13F filing, and Google’s launch of Gemini 3, a next-generation AI model integrated into Search and Cloud services. Berkshire’s investment, attributed to lieutenants Todd Combs or Ted Weschler, signals institutional confidence in Alphabet’s AI and cloud growth. Meanwhile, Gemini 3’s deployment in Search and YouTube enhances user engagement and monetization, while Waymo’s driverless robotaxi expansion in Miami and Texas underscores long-term revenue potential. These moves counter concerns about AI chatbots cannibalizing Search, as Q3 paid click growth accelerated to 7% year-over-year.

Software & Services Sector Mixed as Alphabet Outperforms
The Software & Services sector (led by Microsoft at -0.88% intraday) is mixed, with Alphabet outperforming peers like Microsoft (MSFT) and NVIDIA (NVDA). Alphabet’s 26.9x forward P/E is lower than Microsoft’s 31.8x and Broadcom’s 40.7x, making it a relative value play. The sector’s broader AI optimism is tempered by regulatory scrutiny and valuation concerns, but Alphabet’s cash flow and AI integration provide a near-term edge.

Backtest Alphabet C Stock Performance
The event-study backtest is complete. The 4 % one-day surges in GOOG (2022-01-03 – 2025-11-21) did not consistently deliver a statistically significant edge over the next 30 trading days: average cumulative excess return stays near zero and p-values remain insignificant.Below is an interactive module summarising the study. Please open it to inspect the detailed curves and distribution charts.Key observations:• Win-rate drifts around 55-60 % after day 7 but excess returns remain muted.• No consistent out- or under-performance versus the benchmark within the first month.• Strategy implication: a simple “buy the 4 % pop” in GOOG offers no statistically reliable alpha; consider adding filters (volume spike, macro context, etc.) before deployment.Let me know if you’d like deeper cuts (e.g., shorter holding horizons, stop-loss rules, volume filters) or to test other thresholds.

Bullish Momentum Intact—What’s Next for Alphabet?
Alphabet’s rally is underpinned by Berkshire’s institutional backing and Gemini 3’s commercialization, but CEO Pichai’s AI bubble caution introduces near-term caution. The stock’s 3.73% surge has pushed it closer to its 52W high of $306.89, with RSI near overbought territory. Investors should monitor the $305–$310 range for continuation signals and watch Microsoft’s -0.88% move for sector sentiment. For now, GOOG20251128C310 and GOOG20251128C305 offer high-leverage plays on the AI-driven narrative. Action: Buy GOOG20251128C305 for a $300–$305 breakout, targeting $315.85.
