OK, so I was wrong. I'm man enough to admit when I make a mistake. Last quarter, I wrote about the mixed results at California Pizza Kitchen (NASDAQ:CPKI). There was a bit of good and a bit of bad mixed into its results. Although I liked the company, I just felt it was too expensive based on its modest growth projections. Well, here we are three months later and the stock has increased an astounding 41.8%. Oops.

For its second quarter, the results seem a bit more clear-cut. Net income rose 14.8% over the same period last year, to $6.2 million, or $0.32 per share. Revenues jumped 16.5%, to $119.4 million. Perhaps most impressive, comp restaurant sales grew 8.6%, on top of last year's 6.6% increase.

Not willing to sit still, the company, best known for its innovative pizzas, continues to offer unique new creations, including a Chipotle Chicken Pizza. However, there's more to California Pizza Kitchen than a plethora of tasty pizzas. Its recently updated menu includes new salad offerings and appetizers, which are being well-received.

The company expects the good times to continue and projects third-quarter earnings of $0.32 to $0.33 per diluted share. It is also feeling more confident about its full-year results, raising estimates to a range of $1.16 to $1.18 per share. Unfortunately, analysts have even more faith in its ability and expect earnings of $1.20 per share for the year. That means that even if it meets its own expectations, its stock could suffer if it doesn't reach the level analysts anticipate.

I've already stated that I'm man enough to admit to my mistakes, but I can also be stubborn at times. This is one of those times. Once again, I think the company is progressing nicely and will continue to do so. However, I also think its stock remains rich (particularly after rising 41.8% in one quarter). Sorry, I just think a forward P/E in the mid-20s is too high for its expected growth.
