The VIX, or Volatility Index, quantifies investor uncertainty about the direction of the S&P 500 in the next 30 days. It is also known as the "fear index" since it rises when investors are apprehensive about the market. A low VIX score suggests that investors do not anticipate significant volatility, whereas a high VIX reading implies that investors do. A VIX rating of 10 or less is considered low, while one of 20 or more is considered high. For retail investors tracking market emotion, the VIX can be a useful tool. If the VIX rises, it may imply that investors are growing increasingly anxious and that the market is becoming more volatile. The VIX has been declining in recent weeks. As of August 12, 2023, the VIX is trading at 15.96, which is down from a high of 21.77 in July 2023.
