How To Read It
- Volatility spikes show stress, but what matters most is whether volatility stays high or quickly mean-reverts.
- Rising volatility with flat prices usually signals a more fragile tape than the index headline suggests.
- Compare current levels with prior stress zones rather than treating every jump as equally important.
