The VIX, often called the "fear index," reveals what professional traders expect for market volatility in the coming month. While most retail investors panic during VIX spikes, savvy traders use these moments to find opportunities. Historical data shows extreme VIX readings above 40 often signal market bottoms, creating potential buying opportunities. Understanding different VIX levels - from calm markets (15-20) to extreme crisis (50+) - gives you a powerful edge for timing entries and exits that most traders simply don't have.
