This study compares the information on the implied volatility surface of a stock-index with the corresponding information on the implied volatility surface of the index dividend futures. We outline an optimisation technique for comparing implied volatility estimates based on the Black-Scholes model, Black model and a model-free approach, for stock-index versus dividend-index futures. The implied volatility term-structure of stock-index consistently exceeds that of the dividend index futures thereby confirming the equity volatility puzzle under novel financial data and instruments. However, the magnitude of excess implied volatility reduces as the time-to-maturity increases, suggesting that discrepancies between the two are influenced by inv...
