Accordingly, option prices are expected to carry information about future stock price movements. This study adopts the difference between implied volatility of paired call and put options, volatility spreads, to investigate whether deviations from put-call parity predict the future price movements of the underlying asset. The empirical results indicate that the return predictability of volatility spreads is significantly related to investor sentiments. Moreover, we also find that high investor sentiments reduce the predictability of volatility spreads. Contrarily, the predictability is stable and significant during low investor sentiments.
