Alphabet stock hits record high above $300 as Gemini 3.0 launch drives momentum — Alphabet surged past $300

Alphabet Inc. [GOOGL] stock rallied on Wednesday, November 19, to a new all-time high above the $300 milestone a day after the company launched its most advanced artificial intelligence model, Gemini 3.0. The surge, fueled by renewed optimism around Alphabet’s AI roadmap, marked the biggest single-day volume in November and reaffirmed the company’s leadership position in the tech sector.

- Alphabet surged past $300 after Gemini 3.0 launch reaffirmed its AI leadership position.

- Berkshire’s $4.9 billion stake added confidence to Alphabet’s long-term AI growth story.

- GOOGL RSI near 66 shows room for further upside before overbought conditions emerge.

The stock rose 3.3% during Wednesday’s trading session before profit-taking set in, trimming some gains into the close at $293. Despite the late-session pullback, the bullish sentiment around the Gemini 3.0 launch has carried into Thursday’s premarket, where GOOGL trades around $299, up another 2% from the previous day's close. This puts Alphabet’s week-to-date performance above 7%, setting the stage for its strongest weekly gain in nearly three months.

The latest Gemini 3.0 model is already being integrated into key revenue-generating platforms such as Google Search, underscoring Alphabet’s strategy to compete head-on against OpenAI’s ChatGPT and Microsoft’s AI ecosystem. Analysts suggest the rollout could expand Alphabet’s AI market share as users and enterprise clients seek alternatives offering deeper integration into Google’s ecosystem. The positive tone builds on this week’s earlier bullish sentiment following Berkshire Hathaway’s $4.9 billion disclosed stake in Alphabet, seen as a vote of confidence in the company’s long-term AI potential.

Alphabet insider sales spark mild concern amid strong bullish sentiment

However, some near-term headwinds have emerged following insider sales from senior executives. Filings show CEO Sundar Pichai and VP Amie Thuener O’Toole collectively sold tens of thousands of shares worth nearly $1 million, indicating partial profit-taking at record levels. Still, these transactions have done little to dent investor enthusiasm, as strong buying momentum and institutional accumulation continue to underpin market sentiment.

From a technical perspective, GOOGL’s 4-hour and daily RSI readings of 63 and 66 indicates that the stock is trending in bullish territory without yet entering overbought conditions. This suggests room for continued upside before a potential cooling phase. A sustained hold above $295 would strengthen the case for a breakout above $300, potentially opening the path toward $310. On the downside, immediate support lies at $285, a zone reinforced by the 20-day EMA that has guided the broader uptrend throughout November.

We discussed how Alphabet rose 1.33% to $288 after the Gemini 3.0 release boosted optimism. GOOGL doubled year-to-date, outperforming peers despite macro and legal challenges.
