Option traders are pushing up call option prices in the mortgage investment industry as well as pushing up put option prices in the long-term care facilities industry on Monday.

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.

MOST NOTEWORTHY: CSG Systems, Bankrate and Intercontinental Exchange were today's noteworthy upgrades:

• Citigroup upgraded shares of CSG Systems (NASDAQ: CSGS) following the company's Comcast (NASDAQ: CMCSA) contract renewal to reflect increased visibility and an attractive cash flow yield. The firm raised their target price to $18.50 from $15.
  
• Roth Capital upgraded Bankrate (NASDAQ: RATE) to Buy from Hold citing valuation, the company's announced stock repurchase program, and expectations for some gross margin expansion in 2H08.
  
• BMO Capital upgraded Intercontinental Exchange (NYSE: ICE) to Outperform from Market Perform as they believes the threat of negative legislation to ICE's business has declined sharply in recent days and that current valuation is factoring a much worse outcome than is likely.
