Stocks rallied Tuesday as Wall Street mustered more strength from technology issues while benefiting from a buoyant bond market.

The climb in equities gained momentum when the bond market reversed course and headed higher following morning losses that followed reports of an unexpectedly large increase in home sales and a burst in consumer confidence.

An impressive performance by the Dow Jones industrial average eased fears that last week’s setback on Wall Street was the start of a serious slump. The popular gauge gained 45.78 to 4,714.45.

Gainers beat losers by about 13 to 9 on the NYSE where volume expanded to 373.16 million shares as of 4 p.m. On Monday, 315.13 million shares changed hands on the Big Board’s floor.

Market analysts said several things worked in Wall Street’s favor.

Hugh Johnson, chief investment officer at First Albany Corp., said one positive influence on equities was the Conference Board’s consumer confidence reading, which showed a recovery from a June slump.

The stock market also got a bonus in that bonds coped well with the strong data.
