Any time the volatility skews above 1.00, it is an indication that calls are more expensive than puts. Typically, when calls are more expensive than puts, it means the demand for calls is greater than the demand for puts because investors believe the stock is going to rise in the future and they want to take advantage of that movement by buying calls.

The opposite is also true. Any time a volatility skews below 1.00, it is an indication that puts are more expensive than calls.
