NEW YORK (Reuters) - World shares inched higher on Wednesday, with Wall Street advancing as technology shares rebounded from declines in the prior session, while commodity prices were muted for a second straight session.
In the U.S. equity market, tech shares led the advance, including IBM, which surged 2.3 percent to $167.62 after Barclays upgraded the stock two notches to "overweight" ahead of its quarterly results on Thursday. The S&P technology sector gained 0.61 percent.
Gains were capped however, by a dip in financial shares, off 0.23 percent. Goldman Sachs lost 2.96 percent and Bank of America fell 2.72 after their quarterly results included charges related to the new federal tax law.
"It's very confusing to look at earnings right now because of the tax change charges," said Rick Meckler, president of hedge fund LibertyView Capital Management LLC in Jersey City, New Jersey.
"Investors are trying to figure out what normalized earnings are in a sort of a new environment for them where interest rates are higher, under changing regulations and the new tax code."
