Warren Buffett is the world's best investor, raking in billions for Berkshire Hathaway shareholders with simple, buy-and-hold investing. Naturally, many investors look to Berkshire Hathaway's filings for great stock picks, hoping to learn and tag along with Buffett's investing savvy.

Many of Buffett's biggest holdings aren't new. Two were purchased in the 1980s, and one even dates back to 1964.

In the presentation below, we'll explore why Buffett's such a big fan of leading companies like Procter & Gamble (PG 0.68%), American Express (AXP 0.07%), and International Business Machines (IBM 1.05%). We'll also seek to find out what they all have in common -- from Coca-Cola's (KO 1.50%) worldwide distribution to Wells Fargo's (WFC -0.56%) huge competitive advantage.
