Bucking the trend was Mexican billionaire Carlos Slim, who added $4.4 billion to his fortune after he announced plans to carve up his telecommunications empire. The billionaire said this week that his America Movil SAB (AMXL), the Americas’ largest wireless operator with 272 million subscribers, is bowing to imminent antitrust legislation by selling assets in Mexico to reduce its dominant market share. The 74-year-old said he’s bullish on Mexico and the rest of Latin America, and plans to refocus his investments to take advantage of increasingly cheap borrowing costs.
