About this series
CBOE 9-Day Volatility Index. Same methodology as VIX but using 9-day S&P 500 options instead of 30-day. Measures the market's expectation of volatility over the next ~9 trading days.
Why it matters: The VIX9D/VIX ratio tells you the shape of the front of the volatility term structure. When VIX9D > VIX, the market expects near-term turbulence that fades over the month — typical right before an event like a CPI release or earnings. When VIX9D < VIX, the front is calmer than the back — typical in normal conditions.
How to read it: Watch the ratio, not the absolute number. VIX9D/VIX > 1 is the near-term "kink" that often accompanies known upcoming events or stress. Sudden jumps in VIX9D are more dramatic than VIX because it has less duration.
Caveats: Only goes back to 2011, so limited history for backtesting regime signals.
