NEW YORK (TheStreet) -- U.S. stocks surged Monday after retail sales for September exceeded expectations and Citigroup(C) - Get Report delivered above-consensus earnings.

An agreement by Japan's

Softbank

to acquire a majority stake in

Sprint Nextel

(S) - Get Report

for $20.1 billion aided sentiment as well, continuing the recent spate of deal-making in the wireless communications space.

Monday's other economic data was largely inconsequential to the trading action. A read on manufacturing activity in New York state in October showed less improvement than anticipated while business inventories ticked up nominally in August.

The

Dow Jones Industrial Average

rose more than 95 points, or 0.72%, to finish at 13,424, just below the session high of 13,438.

The blue-chip index lost 2.1% last week, its worst weekly performance since early June. It's now fallen in three of the past four weeks but is still sitting up 9.88% so far in 2012 as of Monday's close.

Winners were well ahead of losers within the Dow, 25 to 5. The biggest percentage gainers were

Bank of America

(BAC) - Get Report

,

Home Depot

(HD) - Get Report

,

JPMorgan Chase

(JPM) - Get Report

,

Merck

(MRK) - Get Report

,

Pfizer

(PFE) - Get Report

, and

Walt-Mart Stores

(WMT) - Get Report

.

Blue-chip decliners included

American Express

(AXP) - Get Report

,

AT&T

(T) - Get Report

,

Coca-Cola

(KO) - Get Report

, and

Verizon

(VZ) - Get Report

.

The

S&P 500

gained nearly 12 points, or 0.81%, to close at 1440, while the

Nasdaq

jumped more than 20 points, or 0.66%, to settle at 3064.

The strongest sectors in the broad markets were health care, financials, capital goods, consumer cyclicals, and technology; every sector finished in the green.

Volume totaled 3.47 billion on the New York Stock Exchange and 1.56 billion on the Nasdaq. Winners outnumbered losers by a roughly 2-to-1 ratio on both exchanges.

The biggest boost for stocks came after the Commerce Department said retail sales for September rose 1.1%; economists were expecting an increase of 0.8%, compared with a 0.9% increase in August, according to

Reuters

.

Capital Economics

said sales are likely enjoying a boost from the release of the iPhone 5 by

Apple

(AAPL) - Get Report

last month but still found good portent in the report.

"The strong rise in retail sales in September was probably flattered by a gain in food prices (triggered by the recent drought) and the release of Apple's iPhone 5," the firm said. "Nonetheless, it now seems likely that third-quarter annualized GDP growth was closer to 2.0% than our previous estimate of 1.5%."

The FTSE 100 in London tacked on 0.2% and the DAX in Germany rose 0.4%. Japan's Nikkei average tacked on 0.5% to snap a four-day losing streak. Hong Kong's Hang Seng added less than 0.1%.

November crude oil futures fell a penny to settle at $91.85 a barrel, while gold for October delivery was down sharply, losing $22.10 to settle at $1,737.60 an ounce.

The benchmark 10-year Treasury slumped 2/32, lifting the yield to 1.671%. The greenback gained 0.04%, according to the

dollar index.

In corporate news,

Softbank

reached a deal Monday to acquire a 70% stake in Sprint for $20.1 billion. The deal is expected to be completed by the middle of 2013. Sprint shares slipped 0.7%.

Sprint is the No. 3 wireless provider, behind

AT&T

(T) - Get Report

and

Verizon Wireless

. The deal will give Sprint more capital to use to compete against its much bigger rivals.

Shares of Citigroup, the third-largest U.S. bank, jumped 5.5% after the company posted third-quarter profit of 15 cents a share. Excluding items, operating profit was $1.06 a share, beating the consensus estimate of 96 cents. Net revenue came in at $19.4 billion, excluding CVA/DVA.

Charles Schwab

(SCHW) - Get Report

, the discount broker, said third-quarter earnings rose 12% to $247 million, or 19 cents a share; analysts forecast profit of 17 cents. The stock advanced 0.6%.

Shares of

Sonic Automotive

(SAH) - Get Report

dropped 8% after the Charlotte, N.C. automotive parts retailer said it expects adjusted earnings of 40 cents a share for the third quarter, below the current average estimate of analysts polled by

Thomson Reuters

for a profit of 43 cents a share in the September-ended period.
