Wall Street opened the week positively, with the S&P 500 up 0.6% despite earlier volatility, as investors await the US administration's announcement on reciprocal tariffs. The outcome could significantly impact the global economy, with potential scenarios ranging from widespread double-digit tariffs to more limited measures. Technical analysis suggests a favorable risk/reward for buying above 5,500 points, targeting 5,800 and 6,100 points, while a drop below 5,400 could signal a bearish trend.
