Berkshire Hathaway's New Alphabet Stake: Market Analysis Report

On November 14, 2025 (EST), Berkshire Hathaway disclosed a new stake in Alphabet Inc. (GOOGL) via its Q3 2025 13F regulatory filing with the SEC [2][4]. The conglomerate acquired

, valued at $4.3 billion as of September 30, 2025—making Alphabet its 10th largest equity holding [2][4]. Concurrently, Berkshire reduced its Apple Inc. (AAPL) stake by ~15% (from 280 million to ~238 million shares), continuing a multi-quarter trend of paring its largest holding [2][4].

The move is notable as Berkshire’s traditional value-investing approach (led by Warren Buffett) has historically avoided high-growth tech stocks. However, the decision may reflect a strategic shift under incoming CEO Greg Abel or portfolio managers Ted Weschler/Todd Combs, as Buffett transitions leadership [1][3].

• Alphabet (GOOGL):
  The stock closed +1.84% at $276.41 on November 14 (filing day) with a trading volume of 31.1 million shares—above recent averages (e.g., 29.5 million on November 10) [0]. After-hours trading saw a further 1.4% gain, per CNBC [3].
• Tech Sector:
  The broader tech sector rose ~2.03% on November 15, aligning with positive sentiment from Berkshire’s endorsement of Alphabet [0].

• Institutional Interest:
  Berkshire’s stake (representing ~0.31% of Alphabet’s outstanding shares) may attract additional institutional investors to GOOGL [4].
• Leadership Transition Signal:
  The move hints at potential changes in Berkshire’s investment strategy post-Buffett, as Abel or the portfolio managers may be more open to tech investments [1].

• Positive for Alphabet: Berkshire’s stake is widely viewed as a “vote of confidence” in Alphabet’s AI (Gemini 2.0) and Google Cloud growth prospects [3].
• Neutral for Apple: The 15% reduction is moderate relative to Berkshire’s remaining $60.7 billion Apple holding, so sentiment impact is limited [4].

• Directly Impacted:
  • Alphabet Class A (GOOGL): Primary beneficiary of Berkshire’s stake.
  • Berkshire Hathaway (BRK.A/BRK.B): Investors may monitor for further tech investments as leadership transitions.
• Related Sectors:
  • Tech: Alphabet’s weight in the sector (~6% of S&P500 Tech) amplifies positive sentiment [0].
  • Consumer Tech: Apple’s reduction has minor spillover effects, offset by its $2.8 trillion market cap [0].

• Decision-Maker Clarity:
  Who exactly approved the Alphabet stake (Abel vs Combs/Weschler)? This will shape expectations for future tech investments [1].
• Stake Growth:
  Will Berkshire increase the stake further in Q4 2025? This requires monitoring the next 13F filing (due February 2026).

1. Alphabet’s AI progress: Adoption of Gemini 2.0 and Google Cloud revenue growth (Q3 2025: +22% YoY per Alphabet’s earnings) [3].
2. Berkshire’s leadership transition: Statements from Abel or Buffett on tech investment strategy.
3. Apple’s performance: Whether the reduction reflects concerns about Apple’s valuation (P/E ~30) or portfolio rebalancing [0].

• Valuation Risk:
  Alphabet’s P/E ratio (27.26) is above Berkshire’s typical value threshold (~15–20), indicating higher volatility in a tech downturn [0][1].
• Strategy Uncertainty:
  If the stake was a one-time move (not a long-term shift), investors may overreact to Berkshire’s endorsement [1].
• Leadership Risk:
  If the decision was made by Combs/Weschler, their future departures could lead to stake reductions [1].

Users should note that Alphabet’s high P/E ratio (27.26) is outside Berkshire’s traditional value framework, which may indicate higher volatility in the event of a tech sector downturn [0][1].
