NEW YORK (TheStreet) -- Shares of DSW (DSW) are up almost 10% following the footwear retailer's top- and bottom-line earnings beat. 

"This was a terrific quarter!" TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, said on CNBC's "Cramer's Mad Dash" segment. 

Earlier in the year, shares of DSW got "hammered" down to the low $20s, Cramer explained, making it a great buy and a potential buyout candidate at the time. 

Now the company is making a comeback as comparable-store sales results are improving. The stock provides a lot of value and is underrated, Cramer said, adding, "I think it goes higher." 

Turning to GT Advanced Technologies (GTAT) , Cramer called it a "speculative play," but added that if its sapphire technology is in Apple's (AAPL) new iPhone 6 screen, the stock could perform quite well.
