NEW YORK (

TheStreet

) -- Retailers are rallying Monday afternoon after the G-20 pledge to keep economic stimulus in place until a recovery is certain.

The S&P Retail Index is rising 1.6% to 401.51, led up by big movers like

RadioShack

(RSH)

,

Zale

(ZLC)

,

Abercrombie & Fitch

(ANF) - Get Report

and

Office Depot

(ODP) - Get Report

.

RadioShack is soaring 13.6% to $20.15 after it was upgraded to outperform

by Credit Suisse.

Last week, the electronics retailer announced it will begin selling

Apple's

(AAPL) - Get Report

iPhone 3G in select stores this month, and nationwide by 2010.

Abercrombie & Fitch was also upgraded

by Credit Suisse to outperform from neutral, sending shares climbing 7% to $37.46.

Analyst Paul Lejuez said the teen retailer will most likely beat Wall Street's estimates when it reports third-quarter earnings on Friday.

Barnes & Noble is increasing 7.6% to $18.34, after announcing several new initiatives. The book store will host the first Sarah Palin book signing for her new autobiography and also unveiled its newly designed kids store on its Web site.

This comes as, last week, rival

Borders

(BGP)

said it would close 200 of its Waldenbooks stores.

Despite a shareholder investigation of

Zale

(ZLC)

, shares of the jeweler are soaring 15.8% to $5.42 this afternoon, regaining some of their massive 26% plunge last week.

Kendall Law Group, a Dallas based law firm that represents investors, said that the investigation is related to possible securities violations concerning admitted errors in Zale's public statements affecting stock purchased between Nov. 16, 2006 and Oct. 29, 2009.

Other notable gainers include

Saks

(SKS)

, which is growing 5.7% to $6.48,

Charming Shoppes

(CHRS) - Get Report

, which is gaining 6.6% to $5.18,

Talbots

(TLB)

, which is up 8.8% to $9.24 and

Office Depot

(ODP) - Get Report

, which is advancing 7.3% to $6.45.

One of the only retailers in the red is

The Gap

(GPS) - Get Report

, after it was downgraded by Barclays Capital to equal weight from overweight.

Analyst Jeff Black said that while the company could do well in 2010, this optimism is clouded by the potential for negative November same-store sales and expense deleverage from increased marketing spending in the fourth quarter.

Shares of the specialty retailer slipped 1% to $22.81 in afternoon trading.
