1 Reason I'd Buy Buffett's Final Favorite Stock And Never Sell

The article highlights Berkshire Hathaway’s final major new portfolio purchase under Warren Buffett — a 17.8 million‑share stake in Alphabet — and makes a bullish case that Alphabet is the premier AI investment. The author argues Google’s full‑stack AI capabilities (TPUs, Gemini, cloud, and massive distribution via Search, YouTube, Android) let it monetize AI at scale, strengthening its advertising and cloud businesses. Market data cited: Berkshire bought the shares in Q3 2025 at an average ~$209.06, the stock now trades above $350, Alphabet’s market cap is roughly $4.2 trillion, and analysts forecast 2025–2028 revenue and EPS CAGRs of ~16% and ~13%. The piece concludes Alphabet remains a long‑term buy given growth, profitability, wide moat and a ~26x forward earnings valuation, despite macro and regulatory headwinds.
