Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Insurer Willis Group Holdings (NYSE: WSH) needs to put in a claim for losses today as high as 13%. The stock finally settled in at a mere 9% decline after the company reported third-quarter earnings this morning.

So what: Revenue for the quarter was $762 million and resulted in earnings per share of $0.41. It was a miss and a beat, as the Street was looking for $764.2 million in sales and $0.37 per share in earnings.

Now what: The company's forward-looking guidance is what's spooking investors, though, as the company sees full-year earnings per share in the range of $2.70 to $2.80 while analysts' consensus calls for $2.87. Despite the soft guidance, Barclays went ahead and upgraded the stock from equal weight to overweight while boosting its price target from $39 to $48. Barclays noted that property and casualty prices should improve, and the company sports a more attractive valuation than its peers.
