Women's specialty apparel retailer Ascena (Nasdaq: ASNA) has been doing very well lately. But apart from its strong quarterly results, there are other aspects that make it even more appealing from an investment standpoint.

Growth through expansion
Ascena performed well in Q4, posting 13.2% earnings growth on an adjusted basis over this quarter last year. The adjusted figure basically excludes one-time costs, such as those related to Ascena's merger with the Justice clothing-store brand, expansion of its operations in Canada, and debt reduction. Net sales also got a boost from favorable comps and an increase in e-commerce sales.

Ascena has been expanding through acquisitions recently. Its recent merger with Justice has worked out well, and management recently reported that the company has the resources to pursue additional acquisitions. Ascena is planning to open at least 125 new locations, which would push the total store count to 2,600 stores even after the planned closing of approximately 30 outlets.

Is Ascena cheap?
The trailing and forward P/E suggest that Ascena looks fairly cheap compared with its peers.

The PEG ratio divides the P/E by a company's estimated five-year growth rate. Lower is better, and at 0.8, Ascena has the lowest ratio among its industry peers. So Ascena might even be undervalued, particularly if its growth plans pan out.

The Foolish bottom line
Despite a recent share-price tumble, Ascena is worth keeping an eye on, especially given its growth prospects and the fact that the company seems somewhat undervalued. Its growth prospects may not really have been factored in to its share price.
