Option traders are pushing up call option prices in the Processed & Packaged Goods industry and are pushing up put option prices in the Packaging & Containers 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.

I'm a big fan of LinkedIn, which is a social network for professionals. In fact, the service has helped me get sources for some of my stories.

But competition is starting to emerge, the latest comes from Hoover's, a part of Dun & Bradstreet (NYSE: DNB). Hoover's has acquired Visible Path, which develops an enetrprise-class social networking platform.

So what makes Hoover's Connect different? Essentially, it's a LinkedIn for individual companies and the system integrates with Microsoft (NASDAQ: MSFT)'s Outlook and other products.

Perhaps the biggest key, however, is privacy. After all, if you are a major executive (who has the power of the checkbook), do you want your contact information freely available?

Hoover's can also leverage its large base of business customers. For example, it is possible to use the system to develop referral paths for various companies, making it to make it easier to make a connection. Actually, according to a study from the University of Chicago and University of North Carolina business schools, it is 16 times more likely to get a response from a trusted source versus a cold call.
