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) popped 20% this week. Pete Najarian said that the WiMax buildout will be a big boon but it might not save Sprint.

Alcoa (AA Quote) jumped 8%. Guy Adami said he's liked the company for a while. With a buyback and a new CEO, he still likes it.

H&R Block (HRB Quote) climbed 5%. Najarian said the company was getting some relief from credit problems.

Advanced Micro Devices (AMD Quote) was up 13%. Adami said oil's not a problem for this company, but he's still not a fan.

True Religion (TRLG Quote) soared 16%. Jeff Macke said the stock is a sell here.

Drops

Clear Channel (CCU Quote) dropped 4%. Macke said it's a quagmire. Avoid it at all costs, he said.

Sotheby's (BID Quote) fell 13%. Karen Finerman said the company's expenses were "out of line."

The Knot (KNOT Quote) slipped 15%. Macke said to short the stock.

Tesoro (TSO Quote) tumbled 14%. Finerman said oil prices are high.
