Spare a thought for Warren Buffett, who lost nearly $1 billion on IBM on Monday and another $1 billion on Coke on Tuesday.
On Monday Buffett lost nearly $1 billion on his third-largest investment, IBM , after the company posted disappointing earnings.
Coke is Buffett's second-largest investment and has been one of the stalwarts of his portfolio for decades. (He left Coke's board in 2006 and his son Howard took a board seat there in 2010).
With 400 million shares, Tuesday's decline of $2.48 cost the Oracle of Omaha $992 million.
"I love Coke. I love the management, I love the directors," Buffett said in a CNBC interview in April, while discussing the recent controversy over the company's executive pay plan.
The losses in IBM and Coke add to a recent rough patch for Buffett, who slashed Berkshire Hathaway's stake in British grocer Tesco earlier this month.
He has described buying into the stock as a "huge mistake."
