Art Technology Group (ARTG) shares are up nicely this morning after Roth Capital’s Nathan Schneiderman raised his rating on the stock to Buy from Hold. Schneiderman notes that the e-commerce software provider’s shares have fallen 25% from a recent peak, creating “a very attractive entry point.”

Schneiderman writes in a research note that the stock’s valuation has fallen to just over 10x free cash flow, “a bargain for a profitable growing company.”

“While we understand that macro conditions are a scary backdrop and that many software names have been pummeled, we point to premium valuations for growth names that are executing - e.g., Ariba (ARBA), Informatica (INFA), Salesforce.com (CRM) and Ultimate Software (ULTI) - to suggest that ARTG could indeed get an attractive valuation even in a tough environment.”

Schneiderman maintains a $4 price target on the stock. ARTG today is up 19 cents, or 6.4%, to $3.17.
