NEW YORK (TheStreet) -- TheStreet's Jim Cramer paused during a busy day at the NYSE to answer questions from his Twitter feed.
He told Debra Borchardt that he likes Yelp (YELP) at current levels, but admitted it's one of the few stocks that could be under pressure from profit taking since it's up 214% in 2013. So many investors have such massive gains that the downward price action is likely causing some to lock in profits, he said.
In fact, that's what caused Cramer to sell the Facebook (FB) position in the Action Alerts PLUS portfolio. He said Facebook stock was becoming "tepid" and his team didn't want to give up the big gains from buying this stock when it was in the $20s.
Cramer says U.S. Airways (LCC) is a buy, as are Delta Air Lines (DAL), Spirit Airlines (SAVE) and United Continental Holdings (UAL). He said the airline sector is one of his top picks to continue outperforming in 2014.
