In 1988, after the stock market crash, Buffett purchased Coca-Cola shares worth US$1.3 billion.

Today, Coca-Cola remains the backbone of Berkshire Hathaway''s largest dividend income.

Current value: Exceeding US$150 billion
Although previously sceptical of technology stocks, Buffett began buying Apple in 2016 with an investment of US$11.1 billion. Today, Apple is the single largest investment in Berkshire Hathaway''s portfolio.
