NEW YORK (TheStreet) -- It's Monday again, which means TheStreet's Jim Cramer is with Debra Borchardt, answering questions from his Twitter feed.
Asked for his opinion on 3D Systems (DDD), Cramer said: "Here's the problem with 3D Systems: It's very overvalued versus Twitter (TWTR).I would own it deep-in-the-money calls." Cramer called 3D "an anointed stock. Going into the end of the year, I think it probably finishes at the high of 2013."
Turning to the teen retail segment, Cramer was asked for his assessment of Aeropostale (ARO).
"This is way too hard," Cramer said. "I don't want to do any teen retail."
Instead, he said: "Just go own Macy's (M). Macy's is having a very good Christmastime."
Regarding Cisco (CSCO) and its recent troubles, Cramer said: "I think that Juniper's (JNPR) taking share from Cisco. I do not think that Cisco is a good stock to own. I prefer Ciena (CIEN), which reported a quarter where the future looks really fabulous. Ciena's the best in show."
