SLIMMING DOWN AT SAKS: Mexican billionaire Carlos Slim Helú continues to cut his stake in Saks Inc. According to regulatory filings late Friday, Inmobiliaria Carso SA, a trust controlled by Slim’s family, sold off another 705,000 shares of the luxe retailer on Wednesday and Thursday, at prices ranging from $11.60 to $11.91. Those stock sales come on top of the 1.5 million shares the fund sold off earlier in the week. Slim continues to hold 24.3 million shares of Saks, keeping him ahead of Diego Della Valle, Tod’s SpA chairman and chief executive officer, who owns 22.7 million shares, or 15 percent of the retailer.
