Institutional flows shift as Berkshire builds stake, Ackman exits, antitrust risks mount

Berkshire Hathaway increased its stake in Alphabet by 83%, making it the investment firm's third-largest position, a move that previously signaled strong institutional allocation, according to 247wallst. Meanwhile, Bill Ackman's Pershing Square exited its Alphabet position in favor of Meta, as reported by Thestreet, potentially affecting past liquidity and sell-side activity. In addition, Alphabet was named as a defendant in an antitrust lawsuit related to its AI business on September 18, 2026, introducing regulatory and legal risks, according to Financefeeds.

Mixed momentum and resistance intensify as technical signals diverge

On the 4-hour chart, GOOGL is trading below the MA-20 at $344.28 and MA-50 at $342.91, with both acting as resistance in the near term. Price remains above the MA-200 on the daily timeframe, which is at $337.82, providing a crucial support zone. The Ichimoku Kijun sits at $345.96 and serves as immediate resistance. Momentum signals are mixed: MACD indicates a buy, ADX is neutral, and the RSI reads 58.36, suggesting moderate buying activity. CCI is in buy territory, Stoch RSI is neutral, Bull/Bear Power signals intraday overbought conditions, and the Awesome Oscillator remains neutral, reflecting divergence among short-term indicators.

Range-bound trade likely as volatility shapes breakout and downside risk

In the near term, GOOGL's price is expected to fluctuate within a range of $332.44 to $352.69 over the next two to three trading days, corresponding to typical volatility for the stock. The base case suggests continued trading inside this corridor, with a 68% probability of an upward move and a 32% chance of renewed decline. A bullish breakout would require a decisive move above the Kijun resistance at $345.96, while a drop below $332.44 would signal increased downside momentum.

Anton Kharitonov, senior analyst at Traders Union, sees Alphabet facing competing institutional signals and rising legal risk. He notes price action remains technically vulnerable below key short-term levels, despite longer-term support. Sentiment is cautious as headline flows turn mixed. "Unless Alphabet reclaims the $345.96 resistance, I remain defensive and see no clear bullish setup in the short term."

Earlier, analysts noted that Alphabet was facing persistent near-term selling pressure despite increasing institutional accumulation and a generally constructive longer-term outlook. The current situation introduces additional regulatory and liquidity considerations, and traders should closely monitor the $345.96 resistance for signs of a breakout that could change the prevailing range-bound setup.
