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 Friday.
Pops
Sprint (S Quote - Cramer on S - Stock Picks) popped 20% this week. Pete Najarian said that the WiMax buildout will be a big boon but it might not save Sprint.

Advanced Micro Devices (AMD Quote - Cramer on AMD - Stock Picks) was up 13%. Adami said oil's not a problem for this company, but he's still not a fan.
True Religion (TRLG Quote - Cramer on TRLG - Stock Picks) soared 16%. Jeff Macke said the stock is a sell here.
