It is extremely useful to observe when the market exhibits counterintuitive movements relative to expectations

The proportion of stocks in the MEXBOL Index trading above their 50-day moving average has surged from below 30% to above 90%, reaching a new extreme level. This recovery in the medium-term trend of Mexico's bellwether stocks is particularly notable against a macro backdrop of implemented trade tariffs and tensions surrounding the United States-Mexico-Canada Agreement (USMCA) - factors that market participants typically view as negative. Typically, when a market or indicator rallies sharply amid adverse news, it signals that investors are looking past immediate risks and positioning for potential upside.
