According to online reports, U.S. President Trump issued a message a few hours before he announced the suspension of tariffs on the 9th, 90 days ago: "Now is a good time to buy stocks!" The abbreviation "DJT" was left at the end, which was interpreted by the outside world as suspected of insider trading. In response, several senators called on Congress to investigate whether Trump was involved in insider trading or market manipulation. According to Time Magazine,"DJT" is the stock code of his media company. It is worth noting that Trump does not often use abbreviations and signatures, and the share price of Trump Media and Technology Group soared nearly 22% after announcing the suspension of tariffs on the 9th, and rose another 5% in early trading on the 10th. Previously, the tariff plan cost Trump $1 billion, with the biggest loss coming from his most valuable asset, Trump Media Technology Group.
