Warren Buffett, is one of America's most revered and successful investors. He is known to eschew companies that he doesn't understand and instead focus on arguably boring firms -- companies that form the bedrock of our consumer society.
His conglomerate invests in the likes of insurance giant Geico, retail behemoths Walmart (WMT) and Costco (COST), sauce and pickle maker Heinz, as well as Brooks, Coca Cola (KO) and a bevy of financial institutions and heavy industries.
