Alphabet C (GOOG) Surges 6.12% on Berkshire's Rare Tech Bet—Is This the Start of a New Bull Run?

Summary
• Berkshire Hathaway's $4.93B stake in Alphabet propels GOOG to record highs at $302.40
• Intraday surge of 6.12% breaks 52-week high of $302.75
• Google Cloud's $155B backlog and $40B Texas data center expansion drive institutional optimism
• Options chain sees 2025-11-28 contracts with 360%+ price change ratios

Alphabet Inc. Class C (GOOG) is experiencing a historic intraday rally, surging 6.12% to $302.40 as of 15:06 ET. The move follows Berkshire Hathaway's rare foray into tech with a $4.93B stake in Alphabet, signaling a strategic shift in Warren Buffett's investment philosophy. With Google Cloud's backlog hitting $155B and a $40B Texas data center expansion underway, the stock is trading at a 28x forward P/E—well below peers like Microsoft (29x) and Nvidia (30x). The 52-week high of $302.75 is within striking distance, with options volatility spiking to 39.33% on the 2025-11-28 chain.

Berkshire's Tech Endorsement Ignites Institutional Demand
Berkshire Hathaway's $4.93B stake in Alphabet represents a seismic shift in the conglomerate's historically tech-averse strategy. This rare move validates Google's AI infrastructure leadership, particularly its Gemini expansion and TPU ecosystem, which are now attracting institutional capital. The purchase of 17.85M shares—valued at $4.93B as of Friday's close—has triggered a 6.12% intraday surge, pushing GOOG to a record high. Analysts note that Buffett's endorsement typically drives short-term gains, as seen in past Berkshire positions. The stock's 14% rise in the December quarter has outperformed the Magnificent 7 ETF (XLK), which has been range-bound since September. This surge reflects growing confidence in Alphabet's ability to monetize AI across Search, Cloud, and YouTube while maintaining disciplined operating leverage.

Software & Services Sector Mixed as Microsoft Trails Alphabet's Momentum
The Software & Services sector is showing divergent performance, with Alphabet's 6.12% rally contrasting against Microsoft's 0.2% intraday gain. While Microsoft's Azure remains a cloud leader, Alphabet's strategic focus on AI infrastructure—bolstered by Berkshire's investment—has created a valuation gap. Google Cloud's 34% YoY revenue growth and 660 bps margin expansion outpace Microsoft's Azure growth trajectory. The sector's top ETF, XLK, has underperformed the S&P 500 in recent months, highlighting Alphabet's unique positioning in the AI-driven growth narrative.
