Grupo Televisa is trading at $2.56, up 8.47% in pre-market, with no confirmed overnight catalyst identified. - The price compares with the October 21 close of $2.36. No confirmed overnight company announcement or earnings release explains the rise; conflicting expected Q3 reporting dates mean an earnings catalyst cannot be confirmed. - The previously announced AT&T Mexico acquisition dates to October 13, not overnight. Broader markets are sharply lower, which does not explain the stock’s move in the same direction.
