Mexico’s stock exchange said it voided transactions involving Bulltick Capital Markets after errors sparked a late-day plunge in the nation’s benchmark index.
The IPC equities gauge sank 2 percent in about three minutes starting at 2:45 p.m. today, before ending the day down 2.3 percent at 38,444.01, according to unadjusted prices provided at the time. The bourse has canceled the trades, which it says affected 13 companies, and is readjusting its indexes to reflect the changes, it said in an e-mailed statement after markets were closed.
“It was a technological error very similar to the flash crash” in the U.S., Alejandro Creixell, a managing partner at Bulltick, said in a telephone interview from Mexico City.
The Dow Jones Industrial Average briefly lost almost 1,000 points in the so-called flash crash of May 2010, which spawned increased regulatory scrutiny for high-frequency traders that use complex computer programs to make trade orders sometimes within milliseconds.
Bulltick executed more sell orders by volume than any other Mexican brokerage today. In the past month, it’s been the 19th most active seller, according to data compiled by Bloomberg.
“Due to the problem that said member generated, and upon its own request, the erroneous offers were canceled,” the exchange said in the e-mail, referring to Bulltick.
Arca Continental SAB (AC*), Mexico’s second-largest Coke bottler, sank as much as 14 percent in intraday trading today. Grupo Aeroportuario del Pacifico SAB, the operator of airports in the Pacific and central regions of Mexico, fell as much as 10 percent.
Beer maker Grupo Modelo SAB (GMODELOC) and Grupo Televisa SAB (TLEVICPO), the world’s largest Spanish-language broadcaster, also retreated.
“All of a sudden the index started falling,” said Roberto Cavazos, who manages about 2 billion pesos ($152 million) in equities at Value Casa de Bolsa SA in Mexico City. “We started to look at different stocks and realized it was an error. There were very unusual trades from Bulltick -- big volumes and prices out of line with the market.”
