Most of the S&P 500 companies have already reported earnings results for the most recent quarter. But scheduled to release their results this week are Medtronic (MDT) and Novell (NOVL), which analysts surveyed by Thomson Reuters expect to post earnings per share (EPS) about same as last year, as well as JDS Uniphase (JDSU), Patterson Companies (PDCO) and Tiffany & Co. (TIF), for which analysts foresee year-over-year earnings growth. Of these, the expectations are highest for Tiffany.

During the three months that ended in July, Tiffany launched an iPhone app and increased its quarterly dividend. Analysts expect the New York-based specialty retailer to report that earnings per share came to 53 cents, a 26.4% increase from a year earlier. Second-quarter revenue is expected to have grown 12.8% to $690.8 million. So far, analysts predict full-year earnings of $2.61 per share (+22.9%) on $3.0 billion (+11.8%) in revenue. Earnings results topped consensus estimates in four of the past five quarters, by 11 cents per share in the first quarter.

Investors call services are pushing put option prices higher in the diversified utilities industry today.

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.

• Ann Taylor Stores Corp. (ANN) shares rallied on heavy volume after it posted better-than-expected Q1 earnings.
• AutoZone Inc. (AZO) Q3 earnings easily beat consensus expectations and same-store sales rose sharply.
• Borders Group Inc. (BGP) posted a wider operating loss, decreasing gross margin, and a same-store sales decline.
• Campbell Soup Co. (CPB) posted strong Q3 results and offered guidance, boosting shares on a down-market day.
• Costco Wholesale Corp. (COST) posted better-than-expected Q3 results, due in part to a surge in membership sales.

Thursday afternoon, Novell (NOVL) reported a fiscal second-quarter profit of 6 cents per share ($19.9 million) -- up from five cents per share ($15.6 million) a year earlier. Adjusted earnings checked in at seven cents per share, matching the consensus estimate. Quarterly revenue of $204 million also matched the Street's expectations. The firm's CFO Dana Russell noted that fiscal second-quarter revenues were in line with expectations and that profits were at the high end of the forecast range.

On March 2, hedge fund operator Elliott Associates made a $5.75 per share offer for Novell (NOVL). The valuation of the deal was roughly $2 billion.

Well, after much consideration, Novell has finally responded. And as should be no surprise, the company says the bid is "inadequate."
