On Wednesday, Investors pushed call option prices higher in the savings & loan industry and pushed put option prices higher in the electric utilities industry.

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.

Bullish Volatility Skews

- Hudson City Bancorp, Inc. (HCBK)---part of the Savings & Loans industry---came in at the top with a volatility skew of 1.13. This may come as a surprise as HCBK is down -6.89 percent for the past month.
