According to 4E monitoring, Trump's tariff policy on Canada has repeatedly reversed on Tuesday, driving the market to stage a "roller coaster" market. At the beginning of the session, the US stock market rose for a while, and then Trump announced an increase of 25% tariffs on Canadian steel and aluminum, and the three major indexes turned down. Soon, news came out that the policy was suspended and the two sides would renegotiate, but the downward trend of US stocks has not changed. After midday, the market changed again, and Ukraine agreed to a 30-day truce. Large technology stocks are emerging, helping U.S. stocks hit new highs, but U.S. stocks weakened again at the end of the trading session. As of the close, all three major stock indexes closed lower, with the Dow Jones Industrial Average falling 1.14%, the S&P 500 falling 0.76%, and the Nasdaq falling 0.18%. Most of the seven technology giants rose. The crypto market rebounded significantly, with Bitcoin rebounding above $83,000 from the low of $76,606, rebounding more than 8%, recouping yesterday's rapid decline. Ethereum rebounded from its low of $1,754 to $1,920, rebounding more than 9%. Some altcoins rebounded even more. The total market value of cryptocurrencies rebounded slightly to $2.77 trillion, a 24-hour increase of 2.5%, and market sentiment rebounded slightly. The recent uncertainty of Trump's tariff policy continues to impact the market, and the potential impact on consumers and the economy has suppressed sentiment on Wall Street. The CPI report at 8:30 tonight has attracted much attention, and investors are looking forward to judging whether the market's concerns about economic stagflation are reasonable. If the data is higher than expected, the market may experience a plunge again.
