At the close of Tuesday's regular session, U.S. stock indices ended in negative territory. The S&P 500 dropped 1.12%, while the Nasdaq 100 fell by 2.24%. The Dow Jones Industrial Average declined by 0.31%.

Asian indices also fell after President Donald Trump imposed a 25% tariff on U.S. auto exports, prompting investors to reduce exposure to riskier assets due to concerns about the growth outlook for the world's largest economy. Auto stocks declined globally. U.S. stock index futures edged higher in early morning trading, while futures on European indices retreated. The Mexican peso dropped following the tariff announcement, along with shares of automakers such as Toyota Motor Corp., General Motors Co., and Ford Motor Co.

Trump's rapidly shifting stance on trade tariffs toward both allies and rivals is exacerbating already elevated market concerns, as investors scramble to assess the impact on global trade and economic growth. Two months into Trump's presidency, market sentiment hasn't improved, with investors tempering their previously optimistic outlook.

Uncertainty surrounding U.S. trade policy is fueling market anxiety, forcing analysts to revise forecasts and factor in potential risks. Companies reliant on international trade are becoming more cautious with their investment plans, fearing the fallout from new tariffs and restrictions.

Central banks are also closely monitoring developments, evaluating the potential impact of trade disputes on inflation and economic growth. The Federal Reserve has already indicated that it will not rush to adjust interest rate policy, which is also weighing on risk assets, including the U.S. stock market.

The reciprocal tariffs expected to be announced next week are likely to be more severe than initially anticipated earlier this week. However, yesterday Trump hinted that he may reduce tariffs for China and other countries, though without offering any specifics. The U.S. President stated that if the European Union collaborates with Canada to harm the U.S. economy, then large-scale tariffs—much higher than currently planned—will be imposed on both countries.

Concerns over the economic fallout of a global trade war are undermining liquidity in U.S. equities, creating headaches for institutional investors and potentially increasing volatility across other markets. Liquidity in S&P 500 index futures has now fallen to a two-year low.

In the commodities market, oil extended its gains after U.S. crude stockpiles posted their largest decline since December of last year. Gold remains near its all-time high.

Technical Outlook for the S&P 500:

Recovery continues. The main task for buyers today will be to break above the nearest resistance at $5740. This would allow the upward momentum to continue and potentially trigger a surge toward the next level at $5766. Equally important for the bulls will be securing control above $5790, which would further solidify their position.

In the event of a downward move due to weakening risk appetite, buyers must step in near the $5715 level. A break below this support would quickly push the index back to $5692 and could pave the way for a deeper decline toward $5642.
