The Mexican Stock Exchange (BMV) saw a minor decrease as it remained near its historic peaks, reflecting a volatile market focusing on the upcoming corporate earnings reports for the fourth quarter. The leading index, S&P/BMV, fell by 0.27 percent, settling at 71,283.63 points during a trading session anticipated to have low volumes due to the U.S. Presidents' Day holiday.

The decline was primarily led by shares from billionaire Carlos Slim's companies, particularly Grupo Carso, which dropped by 2.72 percent to 126.11 pesos. Additionally, Grupo Financiero Inbursa also witnessed a decrease of 2.32 percent, reaching 45.80 pesos. These movements indicate a cautious sentiment among investors as they await significant financial disclosures from major corporations.

Overall, the slight retreat in the stock indices suggests investor hesitance in a backdrop of anticipated earnings reports and external factors, such as the holiday impacting trading volumes. This scenario highlights the interconnectedness of local markets with broader economic events, with traders keenly watching for updates that could influence market trajectories in the coming weeks.
