Understanding Thị trường Volatility: VIX Index and Volatility Giao dịch
2026-03-20 · Market Psychology
What Is the VIX?
The VIX, often called the fear index, measures expected 30-day volatility in the S&P 500. High VIX readings indicate market fear and uncertainty, while low readings suggest complacency. Understanding the VIX is essential for any serious investor.
Interpreting Volatility
VIX readings below 15 indicate low volatility and potential complacency. Readings between 15-25 represent normal market conditions. Readings above 25 signal elevated fear, and above 35 indicates extreme panic — often marking market bottoms.
Strategic Applications
Volatility can be traded directly through VIX futures and ETFs, or used as a timing tool for stock entries. Buying quality stocks during volatility spikes has historically produced superior long-term returns.
