Mexico's leading retailer, Walmex, dropped 2.57 percent to 57.99 pesos while cell phone operator America Movil fell 1.31 percent to 28.62 pesos. On Thursday, an antitrust regulator classed the America Movil as dominant in the cell market and said it could face more scrutiny.
Baking firm Bimbo also contributed to the overall market decline. Its shares gave up 4.13 percent to finish at 82.25 pesos. "Investors in the United States doubt that the recent rally in markets is sustainable, so it affects emerging markets," said Emilio Diez de Sollano, an economic analyst with Mexico consultancy Prognosis.
The peso firmed 0.23 percent to 13.03 per dollar at the central bank's reference close and ahead of a long weekend. The yield on Mexico's 10-year government peso bond was off nearly 2 basis points at 7.79 percent. "The bond market has moved sideways. Investors have confidence in national debt despite any profit-taking in the stock markets," Prognosis said. Mexican markets will be closed on Monday in observance of a national holiday.
