What the VIX Indicates About Stock Returns and Volatility

Summary

The post asks whether the VIX level predicts stock prices or volatility. It reports that average stock returns appear similar across the compared VIX conditions, while the return distribution is wider when spot VIX is high. It also notes more negative outcomes in the high-VIX period, suggesting negative skew. The author's interpretation is that implied volatility is informative about subsequent realized volatility, but not clearly about the direction of stock returns.

For volatility forecasting, the document lists recent realized volatility and current implied volatility as positive inputs, and recent volatility relative to its long-run average as a negative input. It also names the current VIX level relative to its long-run average, with intraday returns and option smile data as possible additions. The post excerpt provides no sample definitions, fitted model, forecast horizon, numerical results, or validation details, and the headings about volatility prediction are not accompanied by analysis. Its findings therefore serve as a brief outline, not a fully documented forecasting method.

Key ideas

• The post finds no apparent difference in average stock returns across the VIX conditions it compares.
• Higher spot VIX is associated with a wider distribution of subsequent returns and more negative outcomes.
• The author treats implied volatility as informative about realized volatility rather than return direction.
• Recent volatility and current implied volatility are listed as positive volatility forecasting inputs.
• The excerpt gives no detailed methodology or validation results for the proposed forecasting inputs.
