U.S. stocks climbed on Wednesday, again lifting the Dow industrials into uncharted terrain, with investor sentiment lifted by corporate earnings and deals.

"The market bias is upwards until there is a reason for investors to lose enthusiasm. At some point, you'd think the laws of Newtonian physics would apply, but we think valuations are full, not stretched," said Mark Luschini, chief investment strategist at Janney Montgomery Scott, of the bull market, which has the Dow and S&P 500 either in, or near, record highs on a near daily basis.

The company's results and "stronger-than-expected PC sales are indicative of business spending," said Luschini.

Wednesday's bounce back in the technology sector is positive, as "you need those heavily weighted sectors like tech and financials, each of which represent 20 percent of the S&P 500," said Robert Pavlik, chief market strategist at Banyan Partners.

The financial sector on Wednesday was among those declining, hit by Bank of America, which fell after reporting a drop of 43 percent in second-quarter profit and a 10-cent miss on earnings per share.
