Monster insider trading alert for this Warren Buffett stock

Coca-Cola (NYSE: KO), one of Warren Buffett’s largest and longest-held investments, has seen notable insider activity involving director Max Levchin.

Filings indicate that Levchin purchased 14,267 shares valued at approximately $998,676.36. The transaction, disclosed in a SEC Form 4 filing, took place on October 23 and was made public on October 27.

Levchin’s purchase, at an average price of around $70.06 per share.

Notably, Coca-Cola’s stock has shown resilience amid market volatility, supported by steady global demand and price increases across its beverage portfolio.

Coca-Cola earnings 

The insider trade disclosure comes as the beverage giant reported third-quarter 2025 revenue of $12.5 billion, a 5% increase from the same period last year, largely driven by price adjustments rather than a rise in sales volume. 

A 6% increase in price and product mix accounted for most of the gains, while global unit case volume rose by only 1%.

On the other hand, performance across beverage categories was mixed. The water, sports, coffee, and tea segment grew by 3%, offsetting a 3% drop in juice, dairy, and plant-based beverages. Meanwhile, Coca-Cola Zero Sugar continued to perform well, but overall sparkling soft drink sales were flat.

Looking ahead, Coca-Cola expects full-year revenue growth of 5% to 6%, signaling steady but unspectacular momentum.

Buffett’s KO stake 

The move also comes as Berkshire Hathaway, Warren Buffett’s conglomerate, maintains a massive position in Coca-Cola, currently valued at about $28 billion. 

Buffett’s stake of 400 million shares represents roughly 9.88% of Berkshire’s total portfolio, with an average acquisition price of $32.90 per share.

Meanwhile, the stock is seeing mixed sentiment. As of press time, KO was valued at $70.06, ending the last session up 0.5%. Over the past month, the stock has rallied nearly 7%.
