According to online reports, according to analysis by The Kobeissi Letter, U.S. stocks experienced short-term sharp fluctuations due to fake news of "tariff postponement" last night. The reasons for the fluctuations can be attributed to technical indicator requirements and market sentiment still in the "buytedip" thinking pattern of a few years ago. Analysts said that in the past two years, investors have become accustomed to buying stocks on dips. This is true for both institutional and retail investors. Even in March, capital poured into stocks as markets fell. Now, if a trade deal is announced, no one wants to "miss" the bottom. However, the article reminds investors that if April 9 approaches and no trade agreement is reached between China and the United States, market sentiment may collapse again. Market sentiment is polarized, with panic reaching March 2020 levels, which means there will be more volatility in the future.
