Here's what CNBC's "Fast Money" traders had to say about some of the market's biggest movers on their "Pops and Drops" segment Thursday.


Amgen ( AMGN - Get Report) popped 6%. Jon Najarian said a judge says Roche can't sell its anemia drug because of patent infringement. He said Amgen has been smart to play hardball with Roche.

Home Depot ( HD - Get Report) was up 3%. Jeff Macke said that companies are responding well to bad news. He also said he likes Costco ( COST).

Millennium Pharmaceuticals rocketed 49%. Najarian said Takeda Pharma paid a huge premium for Millennium. He said the news is bullish for Imclone ( IMCL), among others.

Westlake ( WLK) jumped 7%. Guy Adami said Morgan Stanley upgraded the stock. Chemical companies are huge energy users but are doing well, he said.

Siliconware Precision Industries ( SPIL) tacked on 5%. Tim Seymour said the stock is starting to break out.

Peabody Energy ( BTU - Get Report) rose 3%. Najarian said coal was running like crazy. He said that coal is a demand-driven story.

Western Digital ( WDC) climbed 5%. Adami said that the stock popped on no news today.

Dell ( DELL) moved up 1%. Macke said Michael Dell's return to the company as CEO has not been much of a comeback.


First Marblehead ( FMD) dropped 3%. Don't go near it, Seymour said.

Rite Aid ( RAD) lost 5%. Adami said he loves CEO Mary Sammons, but he's been wrong on the stock for a long time.

Focus Media went down 9%. It's still an interesting play, Seymour said.

TJX ( TJX) lost 4%. Macke said flat same-store sales caused a drop in the stock. That should tell you something, he said.
