CNBC's Stock Pops & Drops From January 15

On CNBC's Stock Pops & Drops, Guy Adami highlighted how Yelp Inc YELP traded 3.98 percent lower on a day when it was upgraded by Evercore ISI. He added that the stock has to hold the $49 price level; otherwise it is going to the low 40s.

Steve Grasso doesn't like to buy stocks that move 9 percent in a single day, like Taiwan Semiconductor Mfg. Co. Ltd. (ADR) TSM did on Thursday. He added that it is important for the stock to hold $21.91, which was the low of the day.

Target Corporation TGT jumped 1.80 percent on the news that it is leaving Canada. Tim Seymour thinks that the stock is going higher.

Brian Kelly said that Pilgrim's Pride Corporation PPC jumped 9.64 percent on the announcement of a special dividend. He wouldn't buy it tomorrow because he wants to wait for a couple of days to see if the stock is going to hold $34.
