Why did the market crash? A reasonable explanation is: The cause of this market plunge can almost entirely be attributed to one piece of news. At 11:20 AM Eastern Time, the U.S. Department of Labor announced that it would release the employment 'situation' for November and October on December 16. By this time, the S&P 500 index had already dropped 70 points from its high at 10:30 AM. Within 40 minutes of the announcement, the S&P 500 index plummeted another 120 points. Now we know that the Federal Reserve is actually making rate decisions in the absence of complete economic data. The market doesn’t like information asymmetry. But is this really enough to wipe out nearly $2 trillion in market value in just a few minutes? We believe this was merely the 'trigger' for a shift in market sentiment. In reality, investors are feeling anxious and uneasy in this market. When the market suddenly drops, investors rush to sell because they believe 'the bubble is about to burst.' The same goes for the opposite. When the stock market surges, the rally accelerates quickly as funds flow back into AI stocks, because people believe 'AI is the next big thing.' The reality is, we now live in a market where any headline can cause trillions of dollars in market value to fluctuate within minutes, and there’s only one reason: Market sentiment is more polarized than ever before.
