Berkshire Hathaway Finds Support at Key Ascending TrendlineBerkshire Hathaway Inc. NewBATS:BRK.BDEXWireNewsWarren Buffett’s Berkshire Hathaway has made a notable shift in its investment portfolio by initiating a $4.9 billion position in Alphabet during Q3. The firm bought 17.9 million shares, giving Berkshire a 0.31% stake in the tech giant. This move stands out because Berkshire has historically avoided high-growth tech names outside of Apple, signaling a strong vote of confidence in Alphabet’s long-term fundamentals. Alphabet remains one of the most financially resilient companies in the world. Its core advertising engine is stabilizing, driven by stronger YouTube demand, improving brand ad spend and rising retail ad budgets. Google Cloud continues to expand margins, turning into a major profit contributor after years of investment. Meanwhile, Alphabet’s AI positioning, through Gemini, Google DeepMind and AI-integrated search, keeps the company at the center of the next major tech cycle. With over $100B in cash and minimal debt relative to its size, the balance sheet remains a fortress, aligning with Buffett's preference for durable, cash-rich businesses. Berkshire’s decision to simultaneously reduce positions in Apple and Bank of America suggests a strategic rebalance toward high-quality growth, especially sectors benefiting from AI and cloud expansion. Alphabet fits this thesis perfectly. Technical Outlook — BRK.B The BRK.B chart shows an exceptionally strong long-term uptrend supported by a clean ascending trendline stretching back to 2022. Each pullback to this trendline has produced a new high, showing persistent institutional accumulation. Price recently bounced strongly off the trendline again and is now pushing toward the $542 resistance zone, a key level last tested during previous peaks. Momentum remains constructive with rising volume confirming renewed demand. As long as BRK.B holds above the trendline, the bullish structure stays intact with upside targets at $542 recent high and potentially $570.
