Retail Winners: RadioShack, Amazon

(Stock prices updated at the close.)

NEW YORK (TheStreet) -- Retailers gave up some of their earlier gains as the dollar turned higher against other currencies today. There remain, however, some standout winners in the sector.

The biggest gainer was RadioShack(RSH Quote), which is soared 15.9% to $18.15 after posting third-quarter revenue that topped Wall Street's expectations.

But the electronics retailer still saw a 24% drop in its profit to $37.4 million, or 30 cents a share, a penny shy of analysts' forecast.

Netflix(NFLX Quote) advanced 0.5% to $55.17, after it announced a partnership with Sony's(SNE Quote) PlayStation.

Amazon(AMZN Quote) is continuing its rally, up 5.2% to close at $124.63. Last week, the e-retailer reported a 69% surge in third-quarter earnings, receiving a boost from sales of Kindle.

Under Armour(UA Quote) is in the green after the athletic apparel company was upgraded to neutral from negative by Susquehanna.

The deal will let Netflix stream movies through PlayStation 3 consoles, which experts believe will help the DVD rental company pick up new customers.

Analyst Christopher Svezia said that sales of the company's ColdGear products, including fleece, outerwear and base layers, have been strong and that he expects to see apparel growth in 2010.

Shares of the company are climbed 5% to close at $33.09.

Yoga-inspired apparel retailer Lululemon Athletic(LULU Quote) grew 1.5% to end at $25.71, but is surging more than 8% in after-market trading after upping its guidance.

The company now expects to earn between 17 cents and 19 cents a share, from prior guidance in the range of 11 cents to 13 cents a share.

Limited Brands(LTD Quote) followed suit, also raising its third-quarter outlook. The specialty retailer expects to post breakeven or a loss of 4 cents a share, better than the loss of 7 cents to 12 cents a share it orginally forecast.

But Limited also predicts October sales will drop more than expected by "low-to-mid single digits, which sent shares tumbling nearly 6% to $18.33 in after-market trading. The company previously forecast flat sales for the month.

Limited wasn't the only retailer in the red. Wal-Mart Stores(WMT Quote) dropped 1.2% to $49.84, Saks(SKS Quote)sank 6.9% to $5.97, Office Depot (ODP Quote) tanked 5.4% to $6.62, GameStop(GME Quote) tumbled 2.8% to $24.08 and Barnes & Noble(BKS Quote) fell 3.4% to $17.49.

J. Crew(JCG Quote) is also giving up last week's gains after it was downgraded by Brean Murray, Carret. Analyst Eric Beder cut the specialty retailer to hold from buy, as the stock is now 1% from his prior price target.

"We believe the potential for further expansion in J. Crew, beyond market-driven movements, is limited in 2009," Beder wrote in a research note. "As such, we believe now is a good time for investors to take profits and wait for a better risk/reward in the name."

Shares of the specialty retailer are declined 2.1% to end the day at $42.72, as a result.
