How to read this ▾
The VIX is the market's 30-day volatility estimate off S&P 500 options — it
rises when traders are afraid. Each day since 2016 is sorted by its VIX close; we show
what S&P 500 did over the next 1–3 months, % positive, and the gap vs the
all-days average.
The effect is one-sided: extreme fear (VIX 25+) has preceded strong returns; a mildly elevated
VIX (20–25) has been the weakest zone. Small overlapping samples — not a forecast.
End-of-day data, refreshed nightly. Forward returns use adjusted closes over 21 / 42 / 63 trading days;
overlapping windows, so samples aren't independent. Not a forecast, not investment advice.
