The stock of women's retailer Coldwater Creek (NASDAQ:CWTR) has been on a tear since March 2003. The stock has risen 11.9 times from its split-adjusted closing low and set a new all-time high Wednesday, after announcing third-quarter results Tuesday night.

Revenue increased 26% from the comparable quarter last year, while net income soared 37%. It was an outstanding quarter, and the peak holiday season is yet to come. Let's peek into what's working and what's expected to happen.

Retail sales (60.6% of total sales) increased by 44%. That doesn't look impressive if you consider that the number of full-line retail stores increased 52.3% to 163 locations, compared with 107 locations at the end of the prior year period's third quarter. Ah, but the rapid store-growth number is misleading. Operating margins for the entire company, which is what really counts, rose from 10.1% last year to 10.3% this year.

The company's other operations, which includes Internet and catalog segments, realized a 7% sales increase. That may look weak, but consider this: The company's Internet operation still managed a 21% sales increase (yet is just 24.7% of total sales). That's strong. And although catalog sales fell 11%, it is important to realize the company's expanding retail base allows customers to pre-shop in the catalog before heading for the store -- or even the Internet.

Coldwater Creek is rolling in the green, too, with $104.7 million in cash and no debt.

So what's the catch? Well, this company, with its rock-solid balance sheet, booming sales, and improving operating margins, does come at a price. Although analysts expect the company to grow earnings by 27.5% annually for the next five years, the stock is selling for somewhere around 48 times this year's expected earnings.

So, is Coldwater Creek reasonably priced? It's a little on the rich side if compared with fast-growing peer Chico's FAS (NYSE:CHS), which trades for 42.8 times this year's forecasted earnings and a 25% annual growth rate. The same is not true of J. Jill Group (NASDAQ:JILL), which will lose money this year and, with 24% annual growth, is priced at a very high 55.2 times projected 2006 earnings. The same goes for Ann Taylor Stores (NYSE:ANN), which is expected to grow more slowly at 15% annually but commands a 26.2 earnings multiple.

Coldwater Creek has momentum in its favor. Although it won't even come close to its multibagger performance over the past two and a half years, as long as margins don't falter, this fast-growing retailer looks poised to deliver excellent results for investors.
