Warren Buffett has been a part of the investment community for decades and over his many years in the game he has stuck to set of principles to guide him.
Those principles have led him back to one stock in particular that he has continued to load up on in recent weeks.

Buffett's Investment Strategy
Berkshire released its annual letter to shareholders last month, and the Oracle of Omaha offered sage advice to the investment advice.
Buffett says that Berkshire's "satisfactory" results over its 58 years are from an advantage that favors long-term investments.
The billionaire mentions the fact that it was 1994 when Berkshire completed its purchase of 400 million shares of Coca-Cola (KO). He says the total cost was $1.3 billion.
"The cash dividend we received from Coke in 1994 was $75 million," Buffett wrote. "By 2022, the dividend had increased to $704 million. Growth occurred every year, just as certain as birthdays."
