California Pizza Kitchen shares fall

Shares slid 58 cents, or 6 percent, to $9.13 in afternoon trading.

After the market closed Thursday, the company said its profit more than tripled in the third quarter, which ended in September. Same-store sales, or sales at locations open at least a year, fell 2.4 percent at company-owned restaurants.

The company, though, said same-store sales dropped 7.3 percent in October as the nation's economy took a turn for the worse and consumers increasingly cut back on spending.

Buckingham Research Group analyst Mitchell J. Speiser said in a note to investors that the company's sales may have been hit harder than some of its competitors because many of its locations are in malls, where consumer traffic has taken a nosedive.

Speiser has a "Neutral" rating on the stock.

California Pizza Kitchen also cut its full-year earnings guidance to 60 cents to 63 cents per share. Analysts polled by Thomson Reuters expect profit of 68 cents per share.
