Warren Buffett bought more than $1 billion in shares of the Coca-Cola Company (KO) in 1988, an amount that was then equivalent to 6.2% of the company. The purchase made it the single largest position in Buffett's Berkshire Hathaway Inc. (BRK.A, BRK.B) portfolio at the time.

Coca-Cola stock remains one of Berkshire Hathaway's biggest holdings today. According to the firm's June 30, 2023, 13F filing, the holding company owned a 9.2% stake worth more than $23 billion in the company. Its 400 million shares also make it Coca-Cola's largest single shareholder.

But why did the Berkshire Hathaway chair make the purchase at that time, when the stock was still reeling after the 1987 market crash? And why has he held onto shares of the soft drink company for so long?

Good Stocks Sunk by the Crash

The stock market crash of 1987 created some attractive opportunities for investors, as all stocks were sold off with little regard to their fundamentals.

Coca-Cola was an example. It was (and is) the dominant company in the beverage industry. As of 2023, it sells more than 200 brands of beverages, from Costa Coffee to vitaminwater, in over 200 countries.

In marketing parlance, Coca-Cola's iconic name and global reach created a "moat" around its core soft drink product. A successful brand builds the name recognition, the distributor network, and the retail relationships that protect it from encroachment by competitors.

Warren Buffett understood that no competitor was going to appear and take away Coca-Cola's market share. On the contrary, the company has steadily absorbed potential competitors over the years and expanded into new trends through purchase such as Ayataka green tea and Dasani water.

An Evolving Investing Philosophy

The Coca-Cola purchase suggested that Buffett's investing philosophy had evolved from Benjamin Graham and a focus on finding companies that had a value exceeding their market prices.

This adjustment was necessary to account for the growing size of Buffett's portfolio, which made it more difficult to take advantage of market inefficiencies. Its sheer size also hindered any attempts at active management and reduced the number of opportunities he could consider that would have a meaningful impact on the portfolio's performance.

Notably, the influence of Charlie Munger, the vice-chair of Berkshire Hathaway, and his philosophy of ethical investing also played a part.

Coca-Cola heralded a change in Buffett's value investing approach, which included "buying bad companies at great prices" to an emphasis on "buying great companies at good prices." By the end of 2020, Buffett's continuing investments in Coca-Cola had returned 1,550%, not including dividends.

Why Buffett Likes Coca-Cola

Although many people may have been skeptical when Buffett first began buying Coca-Cola stock in 1988, shortly after the stock market crash of 1987, Buffett himself defended the buy, saying his favorite holding period is "forever." Here's why he likes the stock:

• Strong brand: Coca-Cola was, and remains, one of the most recognizable global brands. Its products are sold in more than 200 countries around the world, and it's the No. 1 producer of non-alcoholic, ready-to-drink beverages.
• Consistent growth: Coca-Cola's market cap has reached $252 billion. In 1988, when Buffett first started buying shares, the company's market cap was $16 billion.
• Growing dividends: Coca-Cola pays regular quarterly dividends, shelling out $0.46 per share as of September 2023.

Berkshire Hathaway's Coca-Cola Transactions

Buffett first began buying more than 23 million shares of Coca-Cola in 1988 at $2.73 per share (split-adjusted price). The stock split 2-to-1 four times after that; he increased his 6.3% stake to 7.8% by 1994 and more than 9% today.

The investing giant has held on to Coca-Cola stock for decades, with more than 400 million shares on his books by 2023.

The Bottom Line

Warren Buffett's Berkshire Hathaway made a significant investment in shares of beverage giant Coca-Cola in 1988, when the stock's price was depressed following a market crash. Buffett and others at Berkshire recognized Coca-Cola's market advantages, believing that the company was poised to recover. The investment paid off, and Coca-Cola remains one of Berkshire's top holdings.
